Ayutthaya lies at 100.6°E. Its time zone, UTC+7, is built around the 105°E meridian. The 4.4° gap between them means the clock runs roughly 18 minutes ahead of the sun: solar noon arrives at about 12:18 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 59m of daylight. The shortest is 22 December, with 11h 17m. The swing between them is 1h 42m. 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 Ayutthaya the sun comes up earliest on 3 June at 05:48, while the latest sunset waits until 10 July at 18:51.

The sky stays usably light for a while after the sun goes down. In Ayutthaya that civil twilight runs about 21 minutes at the equinox.
