The Tarawa Atoll Sighting Session
Observers on South Tarawa gather at the ocean reef edge on the 29th of each lunar month to search the western horizon across the open Pacific.
Equatorial Horizon Geometry
Because Kiribati straddles the equator, twilight is brief, and the new crescent moon appears directly overhead before descending straight down to the western horizon.
Day Transition Dynamics
The civil calendar updates at 12:00 AM midnight Gilbert Island Time (GILT, Pacific/Tarawa, UTC+12), while religious observance begins at sunset with the Maghrib prayer.
