Frequently Asked Questions

Which holidays are included for Saudi Arabia?

The calculator preselects public holidays for Saudi Arabia sourced from Saudi Labour Law and Royal Decrees. The list and 2024-2029 dates are summarised on this page. Use the Advanced options to layer any regional or industry-specific dates that apply to a particular contract.

What is the Saudi Arabia workweek?

Saudi Arabia's working week runs with a Friday and Saturday (Sunday-Thursday workweek) weekend. The calculator excludes both weekend days and the listed public holidays from the working-day count.

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.
