China October deadlines

National Day is three statutory days, 1 to 3 October, under article 2 of the Public Holiday Measures. A longer closure comes from the year's notice. The principle the notice for 2025 stated is seven days from 1 October, special cases aside, and eight when Mid-Autumn falls within them. The VAT return and the Enterprise Income Tax prepayment for a period that ended in September, the month or the third quarter, are due within 15 days of the period ending, which is 15 October. Statutory rest days can move that date: in its notice for 2026 the State Taxation Administration applied article 109 of the implementing rules of the Tax Collection Administration Law, under which a last day that is a statutory rest day gives way to the day after the rest and three or more consecutive rest days inside the period extend it by those days. Rule 5.2.2 of the Shanghai Stock Exchange's stock listing rules gives a listed company one month from the end of the first nine months of its financial year for the third-quarter report; for a financial year that ends on 31 December that month ends on 31 October. 31 October 2027 is a Sunday. The rule names no other day for a period that ends on a day the exchange is closed.

China reporting cycles and business-day rules

Chinese tax filing periods are not all monthly. Article 30 of the VAT Law (增值税法, in force since 1 January 2026) sets tax periods of ten days, fifteen days, one month or one quarter, fixed for each taxpayer by its tax authority; a taxpayer on a monthly or quarterly period files and pays within 15 days of the period ending. Article 43 of the Law's implementing regulations opens the quarterly period to small-scale taxpayers, to banks, finance companies, trust companies and credit cooperatives among general taxpayers, and to other taxpayers determined by the State Council's tax and finance authorities. Enterprise Income Tax (企业所得税) is prepaid monthly or quarterly as the tax authority determines (article 127 of the implementing regulations as revised in 2024), with the prepayment return due within 15 days of the month or quarter ending and the annual return and final settlement within five months of the year ending (article 54 of the Enterprise Income Tax Law). The annual settlement of individual income tax on comprehensive income is done between 1 March and 30 June of the following year (article 5 of State Taxation Administration Order No. 57 of 2025). A rest day can move these dates: under article 109 of the implementing rules of the Tax Collection Administration Law, a period whose last day is a statutory rest day ends on the day after the rest, and a period containing three or more consecutive statutory rest days is extended by those days. For 2026 the General Office of the State Taxation Administration applied that article to the year's holiday notice and fixed each month's filing deadline in its notice of 10 December 2025 (税总办征科函〔2025〕64号). Payment systems keep their own calendars: the People's Bank of China sets the hours of the High Value Payment System (大额支付系统), with separate arrangements for weekends and statutory holidays, and the operator of CIPS, the cross-border renminbi payment system, publishes that system's working calendar (article 15 of its Business Rules, in force since 1 February 2026). Holidays come in two layers. Article 2 of the State Council's holiday Measures (全国年节及纪念日放假办法) gives all citizens thirteen days off across the year, and for each of the years 2024 to 2026 the General Office of the State Council issued a notice with that year's arrangement: the days taken off and the Saturdays and Sundays worked in exchange. Where a year of this site's China data names no notice, its dates are this site's own projections, to be checked against that year's notice once it is issued.

How October 2027 compares year over year

October 2026 had 17 working days, so October 2027 has 1 fewer working day year over year. On the surrounding months, September 2027 has 19 working days and November 2027 has 22. Looking forward, October 2028 has 17 working days under the same Chinese national holiday calendar.

Using this calculator in China

The 16-day count for October 2027 is this calculator's count of business days in the month: use it to see how many of them fall inside a filing period. A VAT taxpayer whose tax period is a month or a quarter files and pays within 15 days of the period ending (article 30 of the VAT Law, 增值税法, in force since 1 January 2026), and an enterprise files its monthly or quarterly prepayment return for Enterprise Income Tax (企业所得税) within 15 days of the month or quarter ending (article 54 of the Enterprise Income Tax Law). A company listed on the Shanghai Stock Exchange discloses its annual report within four months of the financial year ending, its half-year report within two months of the half-year ending, and its quarterly reports within one month of the first three and the first nine months ending (rule 5.2.2 of the exchange's Stock Listing Rules, April 2026 revision).

How October 2027 is shaped

The headline count answers how many working days October 2027 contains. It does not answer where they sit, and for anything measured in consecutive days rather than cumulative days that second question is the binding one. What follows is derived entirely from the Chinese national holiday calendar and a working week that treats Saturday and Sunday as the weekend, with no assumption about how any particular obligation behaves.

A 31-day month opening the final quarter

October runs 31 days and opens Q4, the last quarter of the calendar year, so everything deferred earlier arrives inside a period that begins here. It shares its weekday alignment with January in a common year. As a 31-day month it carries three weekdays five times, and which three is decided entirely by the day it opens on.

In October 2027 that comes to 16 working days across 31 calendar days, against 19 in September 2027 and 22 in November 2027.

The month opens on a closure

October 2027 begins on a public holiday. National Day (day 1) falls on the 1st, which is a Friday this year, so the calendar month and the working month start on different dates. Any obligation written as "the first of the month" and any obligation written as "the first working day" point at different days in October 2027, and a schedule that treats them as interchangeable is wrong by at least one day here.

The month's first working day is Friday, October 8, and October 2027 carries 16 working days in total.

One working day stands alone

One working day in October 2027 is walled in on both sides. Friday, October 8 sits between National Day (day 7) and the Saturday and Sunday weekend, with no adjacent working day on either side. That single day still counts toward the month's total, but it cannot carry work that needs a second consecutive day, and anything that slips on it slips across a full closure rather than overnight.

The working days of October 2027 arrive in stretches of 1, 5, 5, and 5 days. The longest unbroken stretch runs five days, from October 11 to October 15. A task needing more consecutive working days than that cannot be completed inside a single stretch, whatever the month's total looks like.

The month is back-loaded. It opens with one consecutive day and closes with five, so the room is at the end rather than the start. That is the safer of the two imbalances, because a slip has somewhere to go, but it also makes the opening week a poor sample of the month.

Three weekdays occur five times

A 31-day month contains four full seven-day cycles and three days over, so exactly three weekdays occur five times and the other four occur four times. In October 2027 the three are Sunday, Friday, and Saturday. Which three it is follows entirely from the weekday the month opens on, which is why the working-day count of a 31-day month moves year to year even when its holidays do not.

Only Friday among them is a working day, so part of the surplus is absorbed by the Saturday and Sunday weekend and never reaches the working total. That split is why two months of the same length can carry different working-day counts without any holiday being involved.

A month with several closures

October 2027 carries five Chinese national closures on working days: National Day (day 1) on October 1, National Day (day 4) on October 4, National Day (day 5) on October 5, National Day (day 6) on October 6, and National Day (day 7) on October 7. At this density the month's working-day total stops being a useful planning number on its own, because the days that remain are cut into short stretches rather than distributed evenly.

The run structure above is the figure to plan against. Where several closures cluster, a month can hold a respectable total and still offer no stretch long enough for a multi-day deliverable, and only the run lengths show that.

The closure arrives before any working day has passed, so October is interrupted before it has started and the whole of its 16 remaining working days sit after the break.

The closures around this month

October 2027 carries five Chinese national closures of its own, and the months on either side add their own. Where a deadline sits close to a month boundary, the closure that moves it is as likely to be outside the month as inside it.

Looking outside the month, the last was Mid-Autumn Festival (day 3) (approximate) on September 17, 2027, 14 calendar days before October began and the next is Spring Festival (day 1) (approximate) on January 26, 2028, 87 calendar days after it ends.

Across the whole of 2027 the Chinese national calendar puts 22 closures on working days, of which five fall in October. That ratio, rather than the raw count, is what tells you whether a month is carrying more than its share of the year's downtime.

The month ends over a weekend

October 2027 ends on a Sunday, which this calendar treats as weekend. Month-end processing cannot happen on the last calendar day, so it happens earlier and the last few dates of the month carry no settlement at all. The distance between the final working day and the final calendar day is where month-end reconciliations go missing.

The last working day of October 2027 is Friday, October 29. Counting back from there, the third-to-last is Wednesday, October 27, four calendar days before the month closes.

The working month ends on the last working day of a week, so the final stretch is a complete one and nothing is left hanging mid-week. Two calendar days of October follow it with nothing settling on them.

The quarter opens here

October is the first month of Q4. An opening month sets the baseline the rest of the quarter is measured against, and it is the one month where a slip has two further months to be absorbed in. Quarterly targets divided evenly by three ignore the fact that the three months rarely carry equal working-day counts.

Across the whole quarter there are 61 working days, of which 16 fall in October. The other two months carry November 2027 with 22 and December 2027 with 23. It is the smallest of the three, so the quarter's capacity sits mostly in the other two months and a plan that spreads work evenly across the quarter will over-commit October.

The week's first working day is the scarcest

The first working day of the week is the one October gives least often. Anything anchored to the start of the working week (a weekly kickoff, a Monday-morning cutoff, a start-of-week batch) fires fewer times this month than the calendar count suggests, because a closure has taken one of them out.

Counted as worked rather than as occurring, October 2027 gives Monday 3, Tuesday 3, Wednesday 3, Thursday 3, and Friday 4. A weekly commitment pinned to a particular weekday fires that many times in the month, which is the number a rota needs and not the one the calendar shows.

Toward the short end of the year

October sits among the shorter working months of 2027 under the Chinese national calendar. A month reaches this end of the ranking either by being short or by absorbing closures, and the two produce the same headline number while behaving differently: a closure fragments the month, a shorter calendar does not.

2027 carries 239 working days in total under the Chinese national calendar. The longest month of the year is March 2027 with 23 and the shortest is February 2027 with 15, a spread of 8. October ranks 11th of the twelve with 16.

Inside one of the year's denser months

October 2027 carries more than one Chinese national closure, which puts it among the year's denser months. Closures are never spread evenly across a year, so a month's own count says as much about the country's calendar as about the month.

Across 2027 the Chinese national closures fall 6 in Q1, 8 in Q2, 3 in Q3, and 5 in Q4. A further seven holidays land on the Saturday and Sunday weekend and cost no working day at all, which is why a country's holiday count and its working-day loss are different numbers.

The longest uninterrupted run in the 2027 calendar sits between June 11, 2027 and September 15, 2027, 96 calendar days with no Chinese national closure in between. Stretches like that are where multi-week work belongs, and they move from year to year whenever a movable holiday does.

Where the month sits in the year's closure pattern

Closures are not spread evenly across a calendar year. They cluster around fixed anniversaries and around whichever lunar or movable feasts a jurisdiction observes, so two adjacent months can carry very different loads, and the Chinese national calendar is no exception.

2027 opens its Chinese national closures with New Year's Day on January 1, 2027 and ends them with National Day (day 7) on October 7, 2027. The densest month of the year is February 2027 with five closures on working days.

One working day fewer than last year

October 2027 has one working day fewer than October 2026: 16 against 17. On a monthly target that is roughly 6% less working time for the same calendar period, which is the size of gap that shows up as an unexplained miss rather than as a known constraint.

October opens 2026 on a Thursday, 2027 on a Friday, and 2028 on a Sunday. That movement, one weekday in a common year and two after a leap day, is what makes the three counts differ. The number of closures on working days is the same in both years, so the whole of any difference comes from weekday alignment. Looking ahead, October 2028 carries 17 working days.

Anchor dates that do not fall on working days

Four of the common monthly anchor dates in October 2027 land on a day this calendar does not work. A month with this many blocked anchors pushes several cycles onto the same few dates, because each of them resolves forward to the next available working day and those tend to be shared.

The final column is arithmetic, not a legal conclusion. Whether an obligation actually moves when its date is not a working day depends on the instrument that sets it, and this site does not assume a shift rule for any jurisdiction. Where a rule is known it is stated in the holiday data methodology and on the country page it applies to.

Net terms dated in October 2027

An invoice dated the 1st of October on calendar-day Net 30 terms comes due on October 31, 2027, which is not a working day under the Chinese national calendar. A term counted in calendar days can land anywhere in the week, and roughly two days in seven it lands somewhere nothing settles, which is the ordinary reason a payment shows as late by a day or two without anyone being late.

Net 30 and Net 60 are commercial conventions rather than statutory periods, and both are counted here in calendar days, which is how they are almost always written. Where a contract counts in working days instead, use the between-dates calculator with the China calendar selected, because the two produce different dates whenever a closure falls inside the term.

Frequently Asked Questions

How many business days are in October 2027 under the Chinese national holiday calendar?
October 2027 has 16 working days under the Chinese national holiday calendar. The month spans 31 calendar days, of which 10 fall on a weekend and 5 are Chinese national holidays that land on a weekday. The remaining 16 weekdays are countable as working days for invoicing, deadline tracking, and contract math.
Which China holidays affect October 2027?
October 2027 contains 5 Chinese national holidays: National Day (day 1) on Friday, October 1; National Day (day 4) on Monday, October 4; National Day (day 5) on Tuesday, October 5; National Day (day 6) on Wednesday, October 6; National Day (day 7) on Thursday, October 7. The calculator skips each of them. Regional or industry-specific closures may add further non-working days for narrower contract definitions; layer them into the calculator's Advanced options if needed.
Why do Chinese Golden Week closures shift adjacent weekends?
The statutory days off and each year's closure are set by two different instruments, and the weekend working days come from the second. Article 2 of the State Council's holiday Measures (全国年节及纪念日放假办法), as revised by State Council Order No. 795 with effect from 1 January 2025, gives all citizens thirteen days off across the year: one for New Year's Day, four for Spring Festival, one for the Qingming Festival, two for Labour Day, one for the Dragon Boat Festival, one for the Mid-Autumn Festival and three for National Day. Article 7 allows those days to be arranged into longer breaks by moving rest days. For each of the years 2024 to 2026 the General Office of the State Council issued a notice with that year's arrangement: the days taken off and the Saturdays and Sundays worked in exchange (上班). This calculator counts Monday to Friday and leaves out the closure dates in its data. It never counts a Saturday or Sunday, so it does not count the weekend days a notice turns into working days, and a span that contains one of them comes out one business day short of a calendar that follows the notice. For 2026 the Shanghai Stock Exchange's closing schedule lists each make-up day of that year's notice as a weekend closure (周末休市).
Are Hong Kong and Macau covered by this Chinese calendar?
No. The China data covers the days off arranged under the State Council's holiday Measures (全国年节及纪念日放假办法); Hong Kong and Macau publish holiday lists of their own, and this calculator has no calendar for either. Hong Kong has two lists. The Government's gazetted list of general holidays has 17 dated days for 2026 and 17 for 2027, in addition to every Sunday. The Employment Ordinance (Cap. 57) entitles an employee to statutory holidays: 15 since Easter Monday was added on 1 January 2026, 16 from 2028 with Good Friday and 17 from 2030 with the day following Good Friday. The Government of Macau lists 20 public holidays under Decree Law No. 60/2000 for 2026 and 20 for 2027, ten of them in each year marked as obligatory holidays under article 44 of Law No. 7/2008. For a count in Hong Kong or Macau, add the dates under Advanced options as custom dates to exclude.
Why does the business-day count vary year to year?
Two things shift the monthly count for China. First, the day of the week the first of the month lands on changes the count of each weekday. Second, Chinese national holidays anchored to a fixed date shift their weekday across years. Some years a fixed-date holiday lands on a weekend; some countries shift the observance to an adjacent weekday and some absorb it into the weekend. October 2026 had 17 working days, so October 2027 has 1 fewer working day year over year.
When is the last working day of October 2027?
The last working day of October 2027 under the Chinese national calendar is Friday, October 29. The month's last calendar day is Sunday, October 31, which is not a working day, so month-end processing has to happen two calendar days earlier than the calendar suggests. Counting back, the third-to-last working day is Wednesday, October 27.
How many working days in a row does October 2027 offer?
October 2027 has 16 working days in total, but they do not run consecutively. They arrive in four stretches of 1, 5, 5, and 5 days, so the longest unbroken run is five days, from October 11 to October 15. One working day in the month stands alone with a closure on either side.
