Jordan is the only Muslim-majority-country calendar in this codebase's MENA module that includes Christmas Day as a gazetted national public holiday and confirmed ASE closure day, per this project's own documentation, citing official ASE holiday schedules for 2025 and 2026. This reflects Jordan's officially-recognized Christian minority population and is a genuine national statutory holiday, not a market convention borrowed from a Western calendar (contrast with NYSE's or Euronext Paris's Good Friday, both explicitly not national holidays in their respective countries — see XNYS.md, XPAR.md).
Both Eids run a full 4 days each (1–4 Shawwal, 10–13 Dhu al-Hijjah) — the longest observance for either Eid among all MENA calendars in this codebase; most neighbors use 2–3 days per Eid (see the comparison note in SA.md).
Jordan's own religious authority (Ministry of Awqaf / Higher Judiciary Council) determines Islamic dates by moon sighting, and per this project's own documentation, may differ from Saudi Arabia's Umm al-Qura-based dates by ±1 day — the same general MENA-wide caveat found in Bahrain's and Morocco's documentation.
- Islamic holiday sourcing (CBJ/ASE 2024–2026 announcements, Umm al-Qura projection for 2027–2055, data ceiling 2055), the Christmas Day ASE-closure confirmation (2025/2026 schedules), and the 4-day Eid durations (confirmed by official ASE and CBJ holiday announcements for 2024–2026) are documented directly in this project's own source comments (
JordanHolidays.java); no official CBJ/ASE primary-source page was independently captured with a stable citation URL in this pass
