Yes — a full 10-year public holiday calendar is included for Saudi Arabia, with national / federal-level holidays plus religious / movable holidays derived from official sources.

Open HR → Time Off → Saudi Arabia Holidays and click the "Apply to Calendars" button. All active resource.calendar records receive the holidays as resource.calendar.leaves entries, which are then honored by hr.leave.allocation calculations.

Yes. Religious holidays (Easter-based, Eid al-Fitr / Eid al-Adha lunar dates, Diwali, Buddha Purnima, etc. depending on Saudi Arabia) are included alongside national holidays. Lunar holidays carry standard-source estimates with ±1 day precision.

Yes. Each leave entry is stored in UTC but generated relative to the resource.calendar's own timezone, so multi-tenant deployments and employees in different time zones see correct boundaries.

Yes — a built-in ir.cron job runs every January 2nd and re-applies all holidays for the current year to all active calendars. No manual upkeep needed once installed.
