The timezone ICT in Cambodia

Only 1 nationwide time zone

Daylight saving time:	none

Cambodia has an east-west extension of 4.6 degrees of longitude. Given the country's location in Southeast Asia, this corresponds to about 500 kilometers. With such a small extent the course of the sun at different positions in the country hardly matters. The position of the sun in the west of the country deviates from that in the east only about 19 minutes. This means the sun rises and sets 19 minutes later in the west than in the east.


The Indochina Time also applies in Thailand, Vietnam and in Laos.

No daylight saving time in Cambodia

Due to the sun's orbit around the equator, the days are longer in summer (June to September in the northern hemisphere). Countries that switch to daylight saving time in the summer months align the daylight phase with the human rhythm. Unused bright morning hours are thus shifted into the evening (more information on daylight saving time here).

Due to its proximity to the equator, the impact in Cambodia would not be particularly large. Phnom Penh is located just 1,300 km from the equator. A day in midsummer would then not last from 05:37 to 18:27, but from 06:37 to 19:27. The effect would be quite noticeable in the evening, but the sun rising later in the morning falls at a time when many people are already awake. Thus, daylight saving time was never introduced in Cambodia.
