Angkor Wat covers roughly 162 hectares within its moat, making it the largest religious structure in the world. The wider Angkor complex supported a population that may have reached three quarters of a million — plausibly the largest pre-industrial city on Earth.
The clock: the temple is oriented west, and at the spring equinox the sun rises directly over its central tower — the single most crowded sunrise in Cambodia.
Siem Reap lies at 103.9°E. Its time zone, UTC+7, is built around the 105°E meridian. The 1.1° gap between them means the clock runs roughly 5 minutes ahead of the sun: solar noon arrives at about 12:05 rather than 12:00. The zone holds UTC+7 all year — there is no daylight saving here.
The longest day of 2026 is 22 June, with 12h 55m of daylight. The shortest is 22 December, with 11h 20m. The swing between them is 1h 35m. 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 Siem Reap the sun comes up earliest on 2 June at 05:36, while the latest sunset waits until 11 July at 18:36. 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 Siem Reap that civil twilight runs about 21 minutes at the equinox.
