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

Open HR → Time Off → Sudan 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 Sudan) 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.
