India has three national holidays on which the whole country closes. Everything else is either a central-government gazetted holiday that individual employers choose to observe, or a state holiday. Festival dates follow lunisolar calendars and move every year, so they are listed explicitly rather than derived.
Holiday dates for Riyadh and elsewhere come from a dataset last refreshed on 2026-09-12 (date.nager.at plus curated national calendars). Lunar dates — Eid, Chinese New Year, the Jewish holidays — are predicted and can move by a day once officially announced. Regional, state and employer-specific holidays are not included. Confirm anything you are booking a flight around.

Does Riyadh observe daylight saving time?
No. Riyadh stays on AST (UTC+3:00) for the whole year, with no daylight saving changeover.
Do Riyadh and IST share the same working week?
Riyadh works Sunday to Thursday while IST works Monday to Friday, so you share 4 working days a week — Monday to Thursday. Sunday is a normal working day in Riyadh but a weekend in IST. Friday is worked in IST while Riyadh is off. Most Indian offices run Monday to Friday, though some firms still work alternate Saturdays. Saturday availability is worth confirming rather than assuming.

The next holiday in IST is Gandhi Jayanti on 2026-10-02. Indian, Gulf and Western holiday calendars are built on different systems, so the days each side loses rarely coincide.
