The MERA Moon Sighting Apparatus

Chaired by the Minister of Endowments and Religious Affairs alongside the Grand Mufti of the Sultanate, the Main Moon Sighting Committee convenes in Muscat on the 29th evening of each lunar month, reviewing live data feeds from field stations.

The Dual Criteria of Vision & Science

Oman pioneered the integration of Islamic jurisprudence with astronomical physics. If astronomical calculations prove the moon is below the horizon at sunset, the committee does not accept sighting claims, ensuring zero scientific contradiction in national declarations.

Day Transition Dynamics

The Islamic day commences at Maghrib sunset across the Sultanate, while civil digital calendars advance at 12:00 AM midnight Gulf Standard Time (GST / Asia/Muscat, UTC+4).
