Dongguan lies at 113.8°E. Its time zone, UTC+8, is built around the 120°E meridian. The 6.3° gap between them means the clock runs roughly 25 minutes ahead of the sun: solar noon arrives at about 12:25 rather than 12:00. The zone holds UTC+8 all year — there is no daylight saving here.
The longest day of 2026 is 22 June, with 13h 33m of daylight. The shortest is 22 December, with 10h 43m. The swing between them is 2h 50m. 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 Dongguan the sun comes up earliest on 9 June at 05:38, while the latest sunset waits until 5 July at 19:15.
