The 4 Countries Where the Work Week Officially Starts on Sunday

Most of the working world treats Monday as the starting gun for another five days of emails, meetings, and coffee runs. Yet in a handful of countries, that starting gun goes off a full day earlier, on a morning that much of the planet still considers part of the weekend. The reasons behind this quirk are rooted in religion, geography, and economics, and they still shape how millions of people plan their weeks.

Israel: A Sabbath-Driven Calendar

In Israel, the working week has long run from Sunday through Thursday, a schedule tied directly to the Jewish Sabbath. The standard work week in Israel is five days, running from Sunday to Thursday, which is linked to the personal day of rest designated for the majority of the workforce. Friday functions as a short transitional day, since Shabbat begins at sundown and requires preparation time well before evening arrives.

The Israeli workweek runs Sunday through Thursday, with Friday a short day that wraps up in the early afternoon as people prepare for Shabbat, the traditional day of rest that begins Friday at sunset and ends Saturday night. This rhythm has real consequences for productivity culture. Israelis are known for putting in long hours, and one OECD-based comparison found Israelis worked an average of 40.6 hours per week in 2022, ranking them among the top five hardest-working countries among OECD nations.

Saudi Arabia: Sunday Anchors the Kingdom's Work Rhythm

Saudi Arabia represents the largest economy operating on a Sunday start, and the arrangement is anything but recent. In 2013, Saudi Arabia changed the start of its two-day weekend from Thursday-Friday to Friday-Saturday to help coordinate business and banking days with the rest of the world. That single shift effectively locked Sunday in as the first official working day across the kingdom.

The pattern now touches nearly every corner of Saudi life. Saudi Arabia uses a five-day work week from Sunday through Thursday, with Sunday as the first working day and Thursday as the last, and this pattern is standard across government ministries, private companies, financial services, schools, and most retail. Even Ramadan doesn't disrupt the underlying weekly structure, since only the daily hours shrink rather than the days themselves.

Qatar: Sunday to Thursday Across a Booming Economy

Qatar follows the same Sunday-to-Thursday rhythm found elsewhere in the Gulf, and it has become one of the clearer examples of the pattern holding steady even as global business ties expand. Qatar's work week runs Sunday to Thursday with a Friday-Saturday weekend, covering government, private sector, banks, schools, and Ramadan hours. The consistency matters given how much international trade, sports diplomacy, and finance now flows through Doha.

What stands out about Qatar is how uniformly the schedule applies across sectors that might otherwise operate on their own timetables. Friday is the first day of the weekend as the day of Jummah congregational prayer, Saturday is the second weekend day, and this pattern is standard across government ministries, private companies, financial services, schools, and most retail, though a small number of consumer-facing businesses stay open on weekends with staff rotating through the Sunday-Thursday schedule. That leaves Qatari professionals doing business with Monday-Friday countries with roughly four overlapping workdays instead of five.

Nepal: A Himalayan Nation on a Different Schedule

Nepal sits far outside the Middle East, yet it has followed its own Sunday-first tradition for decades, rooted less in a single faith and more in older astronomical reckoning of the week. The standard workweek in Nepal typically runs from Sunday to Friday, with Saturday being the designated weekly rest day. Government offices, banks, and much of the private sector have organized around this pattern for as long as most Nepalis can remember.

Business hours reflect the same structure on the ground. All government offices and banks operate a six-day work week from Sunday to Friday. Notably, in early 2026 the government temporarily adjusted course for its own offices, as citing ongoing disruptions in petroleum supplies due to the conflict in West Asia, the Nepali government decided to implement a two-day weekend for government offices and educational institutions, with public holidays now observed on Saturdays and Sundays. Even so, Sunday remains the traditional and widely recognized start of the working week for the broader business community.

Why These Countries Break from the Global Norm

The Sunday start isn't an isolated oddity confined to four nations; it reflects a wider regional logic built around Friday's religious significance. In many Gulf Cooperation Council countries, the traditional work week runs from Sunday to Thursday, with the weekend falling on Friday and Saturday, reflecting the importance of Friday as the primary day of worship, which means Sunday becomes the first official working day of the week. Israel arrived at a similar structure through its own religious calendar, even though its weekend lands on Friday and Saturday rather than the Gulf's exact mirror image.

Zoomed out across the globe, the split is closer than many people assume. Roughly half the world's population begins the week on Sunday, with 67 countries and over 4 billion people starting the week on Sunday compared with 160 countries and roughly 3.3 billion people starting on Monday. That statistic mostly reflects calendar conventions rather than work schedules, but it helps explain why the Sunday habit doesn't feel foreign to as many people as it might first seem.

What the Sunday Start Means for Global Business

For companies operating across time zones and traditions, the mismatch creates a genuine scheduling puzzle rather than a minor curiosity. For a business in a Monday-Friday country, a Sunday-Thursday partner is working on your Sunday and resting on your Friday, so a US company and a Saudi counterpart overlap on only three days, Monday, Tuesday, and Wednesday. That narrower overlap forces teams to plan calls, contracts, and deadlines with an extra layer of care.

The UAE's experience offers a useful contrast, since it shows the overlap problem can be solved through policy change. The United Arab Emirates abandoned the Friday-Saturday weekend entirely and adopted Saturday-Sunday in 2022, becoming the first Gulf state to fully align with Western markets, while introducing a 4.5-day work week for federal employees running Monday through Friday at noon. That single move restored a full five-day overlap with Western partners, something the four Sunday-starting countries in this article have so far chosen not to replicate on a national scale.

A Different Rhythm, Still Ticking

Sunday mornings in Tel Aviv, Riyadh, Doha, and Kathmandu look nothing like Sunday mornings in London or New York, and that gap isn't closing anytime soon. Each of these four countries has its own reasons for keeping the pattern, whether religious observance, decades of institutional habit, or simple regional alignment with neighbors. For anyone doing business across these borders, the smartest move is simply checking the local calendar before assuming Monday means the same thing everywhere.
