via Khmer Times, 22 September 2022: The equinox of Angkor Wat happens twice a year – yesterday was one instance.
Im Sokrithy, an archaeologist and director of the Department of Research, Training, and Communication said that at 6:30 am on Sept. 22, the sun will rise at the top of Angkor Wat, but with unfavourable weather this week, we may not be able to see this event like every year.
He continued that this September’s Equinox event coincides with the time when the Khmer people are throwing Bai Ben, and following the inscription on the K279 inscription at the end of the 9th century, it is allowed to throw Bai Ben on Equinox night.
The equinox is the time when day and night are approximately equal in length, unlike some normal months, the night is longer than the day or the day is longer than the night that always happens in the world.
