The Sunday-Thursday Work Week in the Middle East

Across much of the Middle East the working week runs Sunday to Thursday, with the weekend falling on Friday and Saturday. For anyone used to a Monday-Friday calendar this inverts the familiar rhythm: Sunday is a normal working day, and Friday, not Saturday, is the start of the weekend. Before going further, one correction that catches out most references: the United Arab Emirates no longer uses this pattern. Since January 2022 the UAE has run a Monday-Friday week, so it is the exception in a region that is otherwise largely Sunday-Thursday.

This guide covers the Sunday-Thursday region country by country, explains the recent UAE change in full, and works through the practical problems it creates: how a deadline behaves when it lands on a Friday, how few working days a US-Gulf relationship actually shares, and how regional banking cutoffs follow the local week. For the wider global picture, this guide sits under the broader working week around the world overview.

The UAE is the exception: Monday-Friday since 2022

Lead with this because it is the single most common error in any write-up of the region. Effective January 2022, the United Arab Emirates moved from a Sunday-Thursday week to a Monday-Friday week, with a Saturday-Sunday weekend for the federal public sector and schools and a shortened Friday for government workers. The UAE was the first Gulf state to align its weekend fully with Europe and the Americas, and it remains the outlier among its neighbours.

The reason this matters so much is that a large amount of online material, and a lot of institutional memory, still treats the UAE as a Sunday-Thursday country. If you schedule a Dubai or Abu Dhabi counterpart as though Friday were a working day there, you will be wrong: Friday is now part of the weekend. Treat the UAE as a Monday-Friday market, and use the UAE business day calculator, which applies the post-2022 Saturday-Sunday weekend.

Country by country

The genuinely Sunday-Thursday markets, with a Friday-Saturday weekend, include the following.

Saudi Arabia. The largest economy on the Sunday-Thursday pattern. Saudi Arabia moved its weekend from Thursday-Friday to Friday-Saturday in 2013, keeping Friday as a rest day while gaining Saturday to align better with global markets. The working week is Sunday through Thursday. See the Saudi Arabia business day calculator for the Friday-Saturday weekend applied to working-day counts.

Egypt. Runs a Sunday-Thursday week with a Friday-Saturday weekend, the standard pattern for government, banking, and most private business. The Egypt business day calculator reflects this.

Qatar. Sunday-Thursday with a Friday-Saturday weekend, in line with most of the Gulf Cooperation Council. The Qatar business day calculator applies the regional weekend.

Israel. Also Sunday-Thursday, but on a different basis. The Israeli week centres on Saturday, the Jewish Sabbath, with Friday operating as a short day in many workplaces ahead of the Sabbath that begins Friday evening. Sunday is a full working day. The Israel business day calculator uses the Friday-Saturday weekend for counting.

Kuwait, Bahrain, Oman, Jordan, and Iraq. All run Sunday-Thursday working weeks with a Friday-Saturday weekend. These do not have dedicated calculators on this site, but the working-day logic is the same as Saudi Arabia or Qatar: count Sunday through Thursday and exclude the local public holidays.

Why Friday and Saturday

The rest days sit where they do for reasons of religious observance, which is the answer to why the region differs from the Monday-Friday world. Friday is the day of congregational Jumu'ah prayer in Islam, which is why the weekend across Muslim-majority Gulf and Arab states is built around Friday. Saturday is the Jewish Sabbath, observed from Friday evening to Saturday evening, which is why Israel's week ends on Thursday and treats Friday as a short day. In both cases the working week runs Sunday to Thursday, but the anchor day differs: Friday prayer in the Arab states, the Saturday Sabbath in Israel.

When a deadline lands on a Friday

The most common practical question is what happens to a deadline that falls on a weekend day in the region. If a contract gives a Saudi counterparty until a date that turns out to be a Friday, that day is part of the weekend, so the obligation does not fall due on a working day; under most conventions it rolls forward to the next working day, which in Saudi Arabia is the following Sunday. The same applies to a Saturday deadline. The mechanics are identical to a Monday-Friday country rolling a Saturday or Sunday due date to Monday, but the days involved are different, and assuming the wrong weekend produces a due date that is off by the whole weekend. The Saudi Arabia business day calculator handles this automatically: enter the dates and it counts Sunday-Thursday and skips the Friday-Saturday weekend, so a deadline that lands on a rest day resolves to the correct next working day.

Cross-border scheduling: the three-day overlap

The hardest practical consequence of the Sunday-Thursday week is how little it overlaps with a Monday-Friday partner. A US company working with a Saudi, Egyptian, or Qatari counterpart shares only three working days a week. Monday, Tuesday, and Wednesday are working days on both sides. Thursday is the Gulf week's last day but precedes the US working week's Thursday-Friday tail, so it overlaps in calendar terms, yet Sunday, a normal working day in Riyadh, is a US rest day, and Friday, a US working day, is a Gulf rest day. The reliably shared, both-sides-live window is Monday through Wednesday.

That three-day overlap shapes how cross-border work should be planned. Anything that needs both parties active, a live call, a same-day approval, a back-and-forth negotiation, should be scheduled into Monday-Wednesday wherever possible. Work that can be handed off asynchronously can use the wider span, but a project that depends on daily synchronous contact effectively has a three-day week, not a five-day one, and timelines should be built on that basis rather than on an assumed five-day overlap.

It also helps to use the edges of the overlap deliberately. A Monday-Friday team can treat its own Sunday evening as the moment to send anything the Gulf side needs first thing in their Sunday morning, and the Gulf side can use its Thursday to clear items the Western partner will pick up on the following Monday. Naming who owns each handoff, and on which day, turns the narrow overlap from a constraint into a predictable rhythm rather than a weekly scramble to find a shared hour.

Banking and payment cutoffs

Payment systems in the region settle on the local Sunday-Thursday week, which creates a predictable trap for partners on a Monday-Friday calendar. A payment initiated from a Monday-Friday country late on a Thursday will arrive as the Gulf weekend begins, so it may not settle until the receiving banks reopen on Sunday. In the other direction, a payment sent from the Gulf on a Thursday into a Monday-Friday market can stall over that market's Saturday-Sunday weekend. The two weekends only partially overlap, on Saturday, so there is no single day that is reliably a settlement day in both, and a transfer can lose two to four days simply by being timed across the mismatched rest days. For anything time-sensitive, count the cutoff against the destination's banking week and allow for the weekend gap on whichever side it falls.

Ramadan and the regional calendar

Two regional features compound the work-week effect and are worth planning around. The first is Ramadan, the Islamic holy month, during which several Gulf states reduce the legal working day by around two hours for the whole month. Offices open late, close early, and run at a slower pace, so a project scheduled across Ramadan should assume reduced throughput even on working days, not just the usual Friday-Saturday weekend. Because Ramadan follows the Islamic lunar calendar, it moves roughly eleven days earlier each year on the Gregorian calendar, so its dates are not fixed and need checking for the specific year you are planning.

The second is the set of public holidays themselves. The major Islamic holidays, Eid al-Fitr at the end of Ramadan and Eid al-Adha during the pilgrimage season, are multi-day closures that also move on the Gregorian calendar from year to year, and their exact dates are often confirmed only days in advance by moon sighting. National days and other fixed-date holidays layer on top of these. The practical consequence is that the Sunday-Thursday weekend is only the baseline; for an accurate working-day count in any of these countries you also need the year's holiday calendar, which the country calculators on this site maintain. Combine the right weekend with the right holiday set, and a regional deadline becomes reliable rather than a source of avoidable surprises. When in doubt on a high-stakes date, confirm directly with your counterpart, because a locally observed closure can extend a multi-day holiday in practice beyond the dates on a printed calendar.

FAQ

Which Middle Eastern countries use a Sunday-Thursday work week?

Saudi Arabia, Egypt, Qatar, Kuwait, Bahrain, Oman, Jordan, and Iraq run a Sunday-Thursday working week with a Friday-Saturday weekend, and Israel runs the same Sunday-Thursday calendar around the Saturday Sabbath. The United Arab Emirates used this pattern until January 2022 but now runs Monday-Friday.

Does the UAE still use a Sunday-Thursday week?

No. Since January 2022 the United Arab Emirates has used a Monday-Friday week with a Saturday-Sunday weekend for the public sector and schools, and a shortened Friday for government staff. It is the exception in an otherwise largely Sunday-Thursday region, and references that still call it Sunday-Thursday are out of date.

If a deadline falls on a Friday in Saudi Arabia, when is it actually due?

Friday is part of the Saudi weekend, so a deadline landing on a Friday does not fall due on a working day. Under most conventions it rolls forward to the next working day, which in Saudi Arabia is the following Sunday. The same applies to a Saturday deadline. A business day calculator set to Saudi Arabia handles the roll-forward automatically.

How many working days do a US and a Gulf business share each week?

Three: Monday, Tuesday, and Wednesday. Sunday is a working day in the Gulf but a US rest day, and Friday is a US working day but a Gulf rest day, so the reliably shared window for live, both-sides-active work is Monday through Wednesday. Plan synchronous coordination into those three days.

Why is the Middle Eastern weekend on Friday and Saturday?

Friday is the day of congregational Jumu'ah prayer in Islam, so the weekend across the Muslim-majority Gulf and Arab states is built around it. Israel's weekend centres on Saturday, the Jewish Sabbath. Both produce a Sunday-Thursday working week, differing only in whether the anchor rest day is the Friday prayer day or the Saturday Sabbath.
