Israel reporting cycles and business-day rules

Israeli business-day cycles align with Mas Hachnasa (Israel Tax Authority) monthly VAT deadlines on the 15th of the following month, Bituach Leumi (National Insurance Institute) monthly contributions, and quarterly corporate income tax instalments. The Bank of Israel operates ZAHAV as the wholesale RTGS system on bank business days. The workweek is Sunday through Thursday; Friday is a half-day in many sectors and Saturday (Shabbat) is a full closure under the Hours of Work and Rest Law. TASE (Tel Aviv Stock Exchange) trades Sunday through Thursday. ISA (Israel Securities Authority) regulates listed-entity disclosures with quarterly cycles.

A Jerusalem law firm uses business-day math to track Hofesh Shavua workweek (Sunday-Thursday) and Bank of Israel financial-services regulatory windows.

Frequently Asked Questions

How many business days are in September 2028 for Israeli public?
September 2028 has 19 working days under the Israeli public holiday calendar. The month spans 30 calendar days, of which 9 fall on a weekend and 2 are Israeli public holidays that lands on a weekday. The remaining 19 weekdays are countable as working days for invoicing, deadline tracking, and contract math.
Which Israel holidays affect September 2028?
September 2028 contains 2 Israeli public holidays: Rosh Hashanah (day 1) on Thursday, September 21; Rosh Hashanah (day 2) on Friday, September 22. Banks and Israel financial markets close on each of these days. 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 is Friday treated as a weekend day in this calculator?
Israel's workweek is Sunday through Thursday under the Hours of Work and Rest Law. Friday is a partial-day working day for many sectors (typically morning hours only, with banks and the Tel Aviv Stock Exchange closed at 14:00 or earlier), and Saturday (Shabbat) is a full closure for banks, public transit, and most retail. This calculator uses Friday-Saturday as the conservative weekend pair, treating Friday as a non-business day for B2B settlement purposes. Tech sector and multinational employers in Israel sometimes operate Monday-Friday by individual agreement, but the conservative count is what this calculator emits.
How are the Jewish high holidays handled in working-day math?
The Israeli national holidays follow the Hebrew (lunisolar) calendar and shift by 10-13 days year over year against the Gregorian calendar. The major closures include Rosh Hashanah (2 days), Yom Kippur, the first day of Sukkot, Shemini Atzeret/Simchat Torah, the first and seventh days of Passover, and Shavuot. Yom Ha'atzmaut (Independence Day) on 5 Iyar typically shifts to an adjacent weekday if it would fall on a Friday or Saturday. Tisha B'Av (fast day) is a partial bank closure but not gazetted as a public holiday. This calculator includes the nine major bank-closing dates.
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. September 2027 had 22 working days, so September 2028 has 3 fewer working days year over year.
