Hanoi is located at 21.03°N, 105.85°E. Its latitude determines how dramatically daylight hours change through the year.
The city uses the Asia/Ho_Chi_Minh timezone (GMT+7). It does not observe Daylight Saving Time, so solar times shift gradually through the year without abrupt clock changes.
Solar noon — the moment the sun reaches its highest point in the sky — occurs when the sun crosses the local meridian. In Hanoi this falls around 11:55 in mid-summer and 11:46 in December, reflecting UTC offset and any DST adjustments.
