Did You Know?
In April 1975 the Khmer Rouge ordered Phnom Penh evacuated, and within days a city of roughly two million people was almost entirely empty. It stayed that way for nearly four years. Repopulation began in 1979 and the city did not regain its wartime peak of about two million until the late 2010s.
The clock: Phnom Penh keeps UTC+7. The Khmer Rouge declared 1975 to be Year Zero, which is the most literal attempt anyone has made to restart a calendar.
Phnom Penh lies at 104.9°E. Its time zone, UTC+7, is built around the 105°E meridian. The two very nearly coincide: solar noon — the moment the sun is highest — falls at about 12:00, which is as close to true solar time as a zone this wide can get. The zone holds UTC+7 all year — there is no daylight saving here.
The longest day of 2026 is 22 June, with 12h 48m of daylight. The shortest is 22 December, with 11h 27m. The swing between them is 1h 21m. Inside the tropics the day length stays within a narrow band all year.
The earliest sunrise and the latest sunset do not land on the longest day. In Phnom Penh the sun comes up earliest on 31 May at 05:35, while the latest sunset waits until 13 July at 18:28. The equation of time is what separates them: the Earth's elliptical orbit and axial tilt move solar noon back and forth by several minutes over the year.
The sky stays usably light for a while after the sun goes down. In Phnom Penh that civil twilight runs about 21 minutes at the equinox.
Every figure in this section is computed from the city's own latitude, longitude and IANA time zone using NOAA solar algorithms (Spencer, 1971), accurate to about ±2 arcminutes below 65° latitude.
