Frequently Asked Questions

How many business days are in September 2028 for Saudi public?
September 2028 has 21 working days under the Saudi public holiday calendar. The month spans 30 calendar days, of which 9 fall on a weekend and 0 are Saudi public holidays that lands on a weekday. The remaining 21 weekdays are countable as working days for invoicing, deadline tracking, and contract math.
Which Saudi Arabia holidays affect September 2028?
September 2028 contains no Saudi public holidays that fall on a weekday. Banks, the central clearing system, and Saudi Arabia financial markets keep their normal schedule throughout the month under this calculator's national-only holiday set.
Why does Saudi Arabia have a Sunday-Thursday workweek?
Saudi Arabia's workweek is Sunday through Thursday with a Friday-Saturday weekend, established by royal decree to align with the Islamic Friday congregational prayer (Jumu'ah). This calculator uses a Friday-Saturday weekend pattern. Saudi banks, government offices, Tadawul (Saudi Stock Exchange), and most private-sector employers observe this schedule. The Sunday-Thursday workweek aligns Saudi business days with GCC counterparties (UAE pre-2022, Qatar, Kuwait, Bahrain, Oman) for regional commerce.
What is the difference between Zakat and Saudi corporate income tax?
Saudi nationals and Saudi/GCC-owned entities pay Zakat at 2.5% on the higher of the Zakat base or adjusted net income, under the Zakat regime administered by ZATCA (Zakat, Tax and Customs Authority). Non-Saudi and non-GCC-owned entities pay corporate income tax at 20% under the Income Tax Law. Mixed-ownership entities apportion. Both regimes follow the same filing calendar: quarterly declarations and annual returns due 120 days after fiscal year-end. This calculator's working-day counts apply equally to both regimes for deadline tracking.
Why does the business-day count vary year to year?
Two things shift the monthly count for Saudi Arabia. First, the day of the week the first of the month lands on changes the count of each weekday. Second, Saudi 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 also had 21 working days, so the working capacity is unchanged year over year.
