Saudi Arabia Working Day

Checks a date against the Friday-Saturday weekend baseline and exact 2026-2029 authority events.

When to use

You need a deterministic Saudi Arabia Saudi Central Bank financial institutions result.

Do not use when: Financial-institution scope only. MHRSD business-sector leave, RTGS-specific intervals, government offices, private-employer rosters, Hajj-season branch exceptions and Umm al-Qura forecasts are not inferred.

Example user requests

Saudi Arabia: SAMA Eid Al-Fitr interval.
Saudi Arabia: Friday/Saturday weekly baseline.
Saudi Arabia: National Day Saturday substitution.

Formula

is_working_day = not an official Friday/Saturday weekend date and no exact authority event

FAQ

Does this answer every Saudi employer?

No. It is the SAMA financial-institution calendar. MHRSD business-sector rules, RTGS dates and employer schedules are separate scopes.
