Islamic authorities in Pakistan and Saudi Arabia observed the Dhul Hijjah crescent moon on Sunday, May 17, to determine the start of Eid al-Adha [1].

The sighting is critical because it establishes the official dates for the Hajj pilgrimage and the subsequent holiday celebrations for millions of Muslims worldwide [3, 4].

In Pakistan, the Zonal Ruet-Hilal Committee convened to coordinate the sighting efforts [1]. The committee's findings are essential for the national government to announce the official lunar calendar for the region [1].

Simultaneously, the Supreme Court of Saudi Arabia managed the announcement process in the Kingdom [1]. As the custodian of the Two Holy Mosques, Saudi Arabia's determination often serves as a primary reference point for the global Muslim community [1, 2].

The scheduled observation on May 17 corresponds to Dhul Hijjah 1, 1447 AH [2]. This date marks the beginning of the final month of the Islamic lunar calendar, which leads directly into the days of Tashreeq, and the celebration of the sacrifice [3].

Coordination between these regional bodies ensures that the transition into the Hajj season is synchronized. The timing of the moon sighting affects travel arrangements for pilgrims and the scheduling of public holidays across various nations [4].

The sighting is critical because it establishes the official dates for the Hajj pilgrimage.

The synchronization of moon sightings between Saudi Arabia and Pakistan minimizes discrepancies in the start of the Hajj season. Because the Hajj involves massive logistical movements of people into Mecca, a definitive date provided by the Supreme Court of Saudi Arabia and verified by regional committees like the Ruet-Hilal ensures orderly transit and religious adherence across different time zones.
