## Limitations

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. Apply the pinned authority event table over the declared weekday baseline; do not infer uncovered employer or regional schedules. All values are computed from the formula above; no measurement or live data is involved.

## 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.
