The Colombian Moonsighting Network
On the 29th of each lunar month, sighting teams in Maicao, Barranquilla, Bogotá, and Medellín assemble at sunset to observe the western horizon and coordinate with Islamic councils across the northern Andes.
Equatorial Caribbean Observation Conditions
Located between 4°S and 12°N near the equator, twilight is brief, and the crescent moon descends vertically toward the western ocean horizon, providing clean optical separation from the sun.
Day Transition Dynamics & Bogotá Midnight Synchronization
The civil calendar updates at 12:00 AM midnight Colombia Time (COT, America/Bogota, UTC-5), while religious observance begins at sunset with the Maghrib prayer.
