The Ruet-e-Hilal Committee Network
On the 29th of each lunar month, major committees in Delhi, Lucknow, Hyderabad, and Mumbai convene. Imams coordinate by phone and digital channels to evaluate sightings reported from Kashmir to Kanyakumari.
The Kerala Exception
While the vast majority of India follows subcontinental local sighting (falling one day after Saudi Arabia), the coastal state of Kerala occasionally follows its own early maritime sightings or Gulf announcements due to deep historical trade ties.
Day Transition Dynamics
The civil calendar updates at 12:00 AM midnight Indian Standard Time (IST / Asia/Kolkata, UTC+5:30), while the spiritual day begins with the Maghrib Adhan.
