Business Days in August 2027 for Israel

August 2027 has 26 working days under the Israeli public holiday calendar. August 2027 contains one Israeli public holiday on a weekday. The month covers 31 calendar days, of which 4 are Saturday (Shabbat). That count drives invoice cycles, payroll runs, and any contract that defines deadlines as a number of working days in Israel.

public holidays in August 2027

Thu, Aug 12Fast of the Ninth of Av

Israel August deadlines

Employers report and pay national insurance contributions for July to Bituach Leumi on the 15th. On Fridays the Bank of Israel's Markets Department works until 13:15 and, in the 2026 and 2027 calendars, ZAHAV's banking business day ends at 14:00, so a Friday is a short business day at the Bank rather than a day off, and this calculator counts it as a full business day. The Fast of the Ninth of Av falls on Thursday 12 August 2027, a non-business day in the Bank's ZAHAV calendar for 2027, and this calculator counts it as a holiday.

Israel reporting cycles and business-day rules

For Israel the calculator counts the operating days of ZAHAV, the Bank of Israel's RTGS payment system: Sunday to Friday are business days and Saturday is the only weekly rest day. It excludes the days in its data: for 2024 to 2027, every day the Bank of Israel's ZAHAV calendar for the year marks as a non-business day. In the 2026 and 2027 calendars ZAHAV's banking business day ends at 18:30, or at 14:00 on Fridays and holiday eves; those short business days count as full business days here. Government ministries on the five-day week work Sunday to Thursday (Civil Service Regulations, paragraph 31.111, in the National Insurance Institute's copy dated 29 May 2022) and the Tel Aviv Stock Exchange trades Monday to Friday, so a deadline that runs on either of those weeks is not this count. Employers report and pay national insurance contributions to Bituach Leumi on the 15th of each month for the previous month.

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 Israel's own count.

How August 2027 compares year over year

August 2026 also had 26 working days, so the working capacity is unchanged year over year. On the surrounding months, July 2027 has 22 working days and September 2027 has 22. Looking forward, August 2028 has 23 working days under the same Israeli public holiday calendar.

Using this calculator in Israel

The 26 business days of August 2027 are counted on the Sunday-to-Friday week of ZAHAV, the Bank of Israel's RTGS payment system, so every Friday that is not a holiday is in the total. A counterparty on another week needs a different count: a government ministry on the five-day week works Sunday to Thursday (Civil Service Regulations, paragraph 31.111, in the National Insurance Institute's copy dated 29 May 2022), and the Tel Aviv Stock Exchange trades Monday to Friday. For the ministries' week, choose Sunday to Thursday (government ministries) under Working week on the calculator, which then leaves out the Fridays as well as the Saturdays; no setting counts the exchange's week. An employer counting toward Bituach Leumi's payment date should check where the 15th of the month falls.

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 Israeli public holiday calendar and a working week that treats Saturday (Shabbat) 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 26 working days across 31 calendar days, against 26 in July 2027 and 26 in September 2027.

A clean start to the working week

August 2027 opens on the first working day of the week. That is the alignment where the month's own numbering and the working week agree: week one of the month is a whole working week that belongs entirely to August, with nothing borrowed from the month before. Of the 6 possible starts this is the only one where "the first week" and "the first 6 working days" describe the same span.

The opening stretch runs from Sunday, August 1 to August 6, six working days before the first break. August 2027 carries 26 working days in total, so that opening block is 23% of the month's working capacity.

One working day stands alone

One working day in August 2027 is walled in on both sides. Friday, August 13 sits between Fast of the Ninth of Av and the Saturday (Shabbat) 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 August 2027 arrive in stretches of 6, 4, 1, 6, 6, and 3 days. The longest unbroken stretch runs six days, from August 1 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 six consecutive days and closes with three, 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.

All of them are working days here, so the surplus lands entirely on the working week: Sunday, Monday, and Tuesday each occur 5 times. A weekend of one day can take at most one of them, and had it done so the same month would carry 25 working days rather than 26.

One closure, and where it lands

August 2027 carries a single Israeli public closure on a working day: Fast of the Ninth of Av on Thursday, August 12. 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.

Placed where it is, the closure also strands a working day: the run structure above shows a stretch of exactly one. That is the expensive shape for a single holiday, because it removes a day and devalues another.

ten working days pass before the closure and 16 follow it, which puts the break just short of the month's midpoint. A closure near the middle divides the month into two usable halves rather than trimming one end of it.

The closures around this month

August 2027 carries one Israeli public 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 Shavuot on June 11, 2027, 51 calendar days before August began and the next is Rosh Hashanah (day 2) on October 3, 2027, 33 calendar days after it ends.

Across the whole of 2027 the Israeli public calendar puts nine 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.

A midweek close

The month ends in the middle of a working week. Two working days of the final calendar week fall in August and the remainder in the month after, which makes the closing week a partial period on both sides. A midweek close is the pattern most likely to push month-end tasks into the following month by default, simply because the week continues past the boundary.

The last working day of August 2027 is Tuesday, August 31. Counting back from there, the third-to-last is Sunday, August 29, two 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 78 working days, of which 26 fall in August. The other two months carry July 2027 with 26 and September 2027 with 26. All three months of the quarter carry the same working-day count, which happens when their weekday alignments and closures cancel out exactly.

An uneven working week

The working weekdays of August 2027 are unevenly distributed once closures are removed: two occurrences separate the most frequent from the least. A spread that wide means a weekly commitment can cost noticeably more or less depending only on which weekday it sits on, which is not visible in the month's headline total.

Counted as worked rather than as occurring, August 2027 gives Sunday 5, Monday 5, Tuesday 5, Wednesday 4, 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.

Where the month sits in the year

August sits in the middle of 2027 by working-day count under the Israeli public 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 304 working days in total under the Israeli public calendar. The longest month of the year is December 2027 with 27 and the shortest is October 2027 with 23, a spread of 4. August ranks 5th of the twelve with 26.

Israel closures across the year

A month's working-day count only means something against the country's whole calendar. Two countries that share a weekend and happen to have the same closure-free month can still run very different years, and Israel is placed as follows.

Across 2027 the Israeli public closures fall 1 in Q1, 4 in Q2, 1 in Q3, and 3 in Q4. A further three holidays land on the Saturday (Shabbat) 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 August 12, 2027, 62 calendar days with no Israeli public 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 Israeli public calendar is no exception.

2027 opens its Israeli public closures with Purim (Tel Aviv) on March 23, 2027 and ends them with Yom Kippur on October 11, 2027. The densest month of the year is October 2027 with three closures on working days.

The same count as last year

August 2027 and August 2026 carry the same number of working days, 26 in each. An unchanged total does not mean an unchanged month: the working days sit on different dates and break into different stretches, so a schedule copied forward date by date will not line up even though the capacity has not moved.

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 27 working days.

Common anchor dates in August 2027

Monthly cycles are usually written against a date rather than against an ordinal working day, so where those dates fall decides whether the cycle runs on time. In August 2027 every one of the common anchor dates below is a working day under the Israeli public calendar, which is the least disruptive alignment a month can have and is not the usual case.

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 Israeli public 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 dateNet 30, calendar daysNet 60, calendar days
Dated August 1August 31, 2027September 30, 2027

Dated August 31September 30, 2027October 30, 2027 (rolls to October 31, 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 Israel calendar selected, because the two produce different dates whenever a closure falls inside the term.

Frequently Asked Questions

How many business days are in August 2027 under the Israeli public holiday calendar?
August 2027 has 26 working days under the Israeli public holiday calendar. The month spans 31 calendar days, of which 4 fall on a weekend and 1 is an Israeli public holiday that lands on a weekday. The remaining 26 weekdays are countable as working days for invoicing, deadline tracking, and contract math.
Which Israel holidays affect August 2027?
August 2027 contains one Israeli public holiday: Fast of the Ninth of Av on Thursday, August 12. The calculator skips it. 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 does this calculator count Fridays for Israel?
Because it counts the operating days of ZAHAV, the Bank of Israel's RTGS payment system, which run Sunday to Friday; Saturday is the only weekly rest day. Fridays and holiday eves are short business days there (in the 2026 and 2027 calendars the banking business day ends at 14:00 on them) and count as full business days here. Not every Israeli institution keeps that week. Government ministries on the five-day week work Sunday to Thursday (Civil Service Regulations, paragraph 31.111, in the National Insurance Institute's copy dated 29 May 2022), and the Tel Aviv Stock Exchange trades Monday to Friday, so a deadline that runs on either week is not the default count. For the ministries' week the calculator has a Working week setting: Sunday to Thursday (government ministries) leaves the Fridays out as well and keeps the same holidays.
How are the Jewish high holidays handled in working-day math?
The holidays follow the Hebrew calendar, so their Gregorian dates change from year to year. This calculator's data carries the same nine every year: Passover day 1 and day 7, Yom Ha'atzmaut, Shavuot, Rosh Hashanah day 1 and day 2, Yom Kippur, Sukkot day 1 and Shemini Atzeret/Simchat Torah. For 2024 to 2027 it also carries the other days the Bank of Israel's ZAHAV payment system closes: Purim on its Tel Aviv date, the Fast of the Ninth of Av, the eve of Yom Kippur and the election days of 27 February 2024 and 27 October 2026. One that falls on a Saturday costs no business day here, because Saturday is already off, while one that falls on a Friday does cost one: in 2026, Rosh Hashanah day 1, Sukkot day 1 and Shemini Atzeret fall on Saturdays, and Shavuot falls on Friday 22 May.
Why does the business-day count vary year to year?
Two things shift the monthly count for Israel. First, the day of the week the first of the month lands on changes the count of each weekday. Second, Israeli public 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. August 2026 also had 26 working days, so the working capacity is unchanged year over year.
When is the last working day of August 2027?
The last working day of August 2027 under the Israeli public calendar is Tuesday, August 31. The month's last calendar day is Tuesday, August 31, so the two are the same date this year. Counting back, the third-to-last working day is Sunday, August 29.
How many working days in a row does August 2027 offer?
August 2027 has 26 working days in total, but they do not run consecutively. They arrive in six stretches of 6, 4, 1, 6, 6, and 3 days, so the longest unbroken run is six days, from August 1 to August 6. One working day in the month stands alone with a closure on either side.
