Moon-sighting authorities in Pakistan, Saudi Arabia, and the United Arab Emirates are observing the crescent of Dhul-Hijjah on May 17, 2026 [1].

The determination of the new moon is critical because it establishes the official start of the Islamic month and sets the date for Eid al-Adha celebrations across the Muslim world.

In Pakistan, the Zonal Ruet-Hilal Committee is convening to sight the crescent [2]. The committee's decision will dictate the national calendar for the upcoming religious holiday. Similar observation efforts are being conducted by authorities in Saudi Arabia and the UAE to ensure regional coordination [2].

Astronomical calculations in the UAE have suggested that Eid al-Adha 2026 is likely to begin on July 20, 2026 [4]. However, these calculations serve as a guide and do not replace the traditional sighting of the moon. The official announcement will follow the results of the observations conducted this Sunday [1].

Observation teams in Sharjah and other regions are utilizing both traditional methods and modern technology to confirm the crescent's visibility [4]. The process involves coordinating reports from various zones to reach a consensus on the moon's appearance [2].

Once the Zonal Ruet-Hilal Committee and its counterparts in Saudi Arabia and the UAE confirm the sighting, the date for the start of Dhul-Hijjah will be announced. This timeline governs the period of fasting and preparation leading up to the sacrifice and festivities of the holiday [2].

The determination of the new moon is critical because it establishes the official start of the Islamic month.

The reliance on both astronomical calculations and physical sightings often leads to slight variations in the start date of Islamic holidays between different countries. By coordinating efforts across Pakistan, Saudi Arabia, and the UAE, these authorities aim to minimize discrepancies and provide clarity for millions of worshippers preparing for the pilgrimage and festivities.
