Philippines August deadlines
Form 1701Q for the second quarter is filed on or before August 15, and a corporation's Form 1702Q within 60 days of the close of the quarter, 29 August for a quarter ended 30 June. Form 1601-C and Form 0619-E for July are filed on or before August 10. The yearly proclamation lists Ninoy Aquino Day, 21 August, as a special (non-working) day and National Heroes Day, the last Monday of August, as a regular holiday. PhilHealth premiums for July are remitted on the 11th to 15th of August by employers whose PhilHealth Employer Number ends in 0 to 4, and on the 16th to 20th by those whose number ends in 5 to 9. Proclamation No. 1427 lists Ninoy Aquino Day on Saturday 21 August 2027 and National Heroes Day on Monday 30 August. August 10 is a Tuesday, and August 15 and August 29 are Sundays. Under Revenue Memorandum Circular No. 65-2016 a due date on a Saturday, Sunday or holiday moves to the next business day: Monday 16 August for the 15th and, for the 29th, Tuesday 31 August, because National Heroes Day falls on the Monday.

Those dates in 2027
Two of the dates named above do not fall on a working day in 2027 under the Philippine calendar. A fixed calendar date advances through the week year by year, so this resolution holds for 2027 only.
| Date | Weekday | Status under the Philippine calendar | First working day on or after |
|---|---|---|---|
| August 10 | Tuesday | Working day | |
| August 15 | Sunday | Weekend | August 16, 2027 |
| August 29 | Sunday | Weekend | August 31, 2027 |
This table resolves weekdays and nothing else. Whether an obligation actually moves when its date is not a working day is set by the instrument that creates it, and no shift rule is assumed here for any jurisdiction. The sources behind each calendar are listed in the source register.

Philippines reporting cycles and business-day rules
Philippine business days in this calculator run Monday to Friday, less every regular holiday and special (non-working) day in the year's proclamations. The Bangko Sentral ng Pilipinas suspends its essential operations, PhilPaSS settlement among them, on nationwide regular and special non-working holidays. PESONet, the batch transfer system, settles in three cycles within each business day, at 10:00 a.m., 1:00 p.m. and 4:00 p.m. since 8 July 2024, while InstaPay transfers arrive almost instantly, 24x7, all year round. The quarterly VAT return, BIR Form 2550Q, is filed within twenty-five days following the close of each taxable quarter.

August 2027 working days compared by country
Working-day counts vary across countries because each country observes its own public holidays. The table below shows August 2027 under 11 of the site's 25 holiday calendars; the summary above gives Philippines's own count.
| Country | Business Days | Holidays this month |

| 🇺🇸United States | 22 | None |
| 🇬🇧United Kingdom | 21 | Summer Bank Holiday |
| 🇨🇦Canada | 22 | None |
| 🇦🇺Australia | 22 | None |
| 🇮🇳India | 22 | None |
| 🇵🇭Philippines (this page) | 21 | National Heroes Day |
| 🇫🇷France | 22 | None |

How August 2027 compares year over year
August 2026 had 19 working days, so August 2027 has 2 more working days year over year. On the surrounding months, July 2027 has 22 working days and September 2027 has 22. Looking forward, August 2028 has 21 working days under the same Philippine holiday calendar.
Using this calculator in Philippines
A Makati payroll team uses the 21-day August 2027 count to time its PESONet salary files, because PESONet settles only in its three cycles within a business day; an InstaPay transfer, which runs 24x7, needs no such allowance. A Cebu treasury desk checks the same count against central bank closures, since the Bangko Sentral ng Pilipinas suspends PhilPaSS settlement on nationwide regular and special non-working holidays. A Davao accountant works back from the twenty-five days the BIR allows after each quarter for the quarterly VAT return, Form 2550Q.

How August 2027 is shaped
The headline count answers how many working days August 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 Philippine holiday calendar and a working week that treats Saturday and Sunday as the weekend, with no assumption about how any particular obligation behaves.
The middle month of the third quarter
August runs 31 days and sits in the middle of Q3, so it opens and closes nothing: no quarter, no half, no year. That makes it the month whose working-day count is least likely to be checked and most likely to be assumed. In a common year August shares its weekday alignment with February and March, which is the widest such group in the calendar.
In August 2027 that comes to 21 working days across 31 calendar days, against 22 in July 2027 and 22 in September 2027.
The month opens across a weekend
The 1st of August is a Sunday, a weekend day under the Philippine calendar, whose week runs against a Saturday and Sunday weekend. Nothing that settles on working days moves on it. A month that opens this way loses its first working day to the calendar before any holiday is counted, and monthly cycles keyed to the 1st all resolve forward to the same date, which concentrates them.
The month's first working day is Monday, August 2, and August 2027 carries 21 working days in total.
Five working stretches
August splits into five working stretches. That is the ordinary shape of a month whose only interruptions are its weekends, and it means the month's internal boundaries are all predictable a year in advance: nothing here depends on a holiday date moving.
The working days of August 2027 arrive in stretches of 5, 5, 5, 5, and 1 day. The longest unbroken stretch runs five days, from August 2 to August 6. 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 front-loaded. It opens with five consecutive days and closes with one, so capacity thins toward the end. Work deferred out of the first stretch arrives in a shorter one, which is how a schedule that looked comfortable in week one stops fitting.
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 August 2027 the three are Sunday, Monday, and Tuesday. 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 Monday and Tuesday among them are working days, 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.
One closure, and where it lands
August 2027 carries a single Philippine closure on a working day: National Heroes Day on Monday, August 30. A holiday's cost to a month is not only the day it removes; it is also where the removal falls, because the same closure can extend an existing break or cut a working stretch in half.
It sits directly beside a weekend rather than inside a working week, so it extends an existing break instead of creating a new one. That is the cheapest position a holiday can occupy: the month loses a day but keeps its shape.
20 working days pass before the closure and only 1 follow it. With the break past the midpoint, most of the month's capacity has already been spent when it arrives, so anything the closure displaces competes for a shrinking remainder.
The closures around this month
August 2027 carries one Philippine closure 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 Eid'l Adha (approximate) on May 17, 2027, 76 calendar days before August began and the next is All Saints' Day on November 1, 2027, 62 calendar days after it ends.
Across the whole of 2027 the Philippine calendar puts 14 closures on working days, of which one falls in August. 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.
An early-week close
August runs out after the second working day of its last week. Most of that week belongs to the next month, so the tail of August 2027 is unusually thin: two working days carry whatever the month-end process needs, and the week's remaining capacity is not available to this period.
The last working day of August 2027 is Tuesday, August 31. Counting back from there, the third-to-last is Thursday, August 26, five calendar days before the month closes.
The middle month of the quarter
August is the middle month of Q3. Middle months carry the least visibility in a quarterly cycle: the opening month sets expectations and the closing month is where they are settled, so a shortfall here is the one most likely to be noticed late.
Across the whole quarter there are 65 working days, of which 21 fall in August. The other two months carry July 2027 with 22 and September 2027 with 22. 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 August.
The week's first working day is the scarcest
The first working day of the week is the one August 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, August 2027 gives Monday 4, Tuesday 5, Wednesday 4, Thursday 4, 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.
Where the month sits in the year
August sits in the middle of 2027 by working-day count under the Philippine calendar. The middle of that ranking is where a month's total is least informative on its own, because a mid-ranked month can be a long month carrying closures or a short one carrying none, and the two need different plans.
2027 carries 247 working days in total under the Philippine calendar. The longest month of the year is June 2027 with 22 and the shortest is December 2027 with 19, a spread of 3. August ranks 5th of the twelve with 21.
Inside the year's longest clear run
August 2027 sits inside the longest stretch of 2027 with no Philippine closure in it. Where a month falls relative to its country's closure clusters changes what the same working-day count is worth: an uninterrupted month inside a long clear run behaves differently from one of equal length wedged between two closures.
Across 2027 the Philippine closures fall 4 in Q1, 2 in Q2, 1 in Q3, and 7 in Q4. A further six 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 May 17, 2027 and August 30, 2027, 105 calendar days with no Philippine 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 Philippine calendar is no exception.
2027 opens its Philippine closures with New Year's Day on January 1, 2027 and ends them with Last Day of the Year on December 31, 2027. The densest month of the year is December 2027 with four closures on working days.
A materially longer month than last year
August 2027 carries 2 more working days than August 2026 did (21 against 19). A swing of two or more days in the same month between adjacent years is large: it means the weekday alignment moved and a closure changed position, not just one of the two. Any run-rate carried forward from last year understates this month.
August opens 2026 on a Saturday, 2027 on a Sunday, and 2028 on a Tuesday. That movement, one weekday in a common year and two after a leap day, is what makes the three counts differ. The count of closures on working days differs between the two years as well, so alignment is not the only thing moving. Looking ahead, August 2028 carries 21 working days.
Where the month's anchor dates fall
Two of the common monthly anchor dates in August 2027 land outside the working week or on a closure. The table below resolves each one against the Philippine calendar, together with the first working day on or after it.
| Date | Weekday | Status under the Philippine calendar | First working day on or after |
|---|---|---|---|
| August 1 | Sunday | Weekend | August 2, 2027 |
| August 5 | Thursday | Working day | August 5 |
| August 10 | Tuesday | Working day | August 10 |
| August 15 | Sunday | Weekend | August 16, 2027 |
| August 20 | Friday | Working day | August 20 |
| August 25 | Wednesday | Working day | August 25 |
| August 31 | Tuesday | Working day | August 31 |
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 August 2027
An invoice dated the 1st of August on calendar-day Net 30 terms comes due on August 31, 2027, a working day under the Philippine calendar. Terms counted in calendar days move independently of the working week, so the same term written on two consecutive months can settle cleanly in one and roll across a closure in the other.
| Invoice date | Net 30, calendar days | Net 60, calendar days |
|---|---|---|
| Dated August 1 | August 31, 2027 | September 30, 2027 |
| Dated August 15 | September 14, 2027 | October 14, 2027 |
| Dated August 31 | September 30, 2027 | October 30, 2027 (rolls to November 3, 2027) |
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 Philippines calendar selected, because the two produce different dates whenever a closure falls inside the term.
