Seoul is located at 37.57°N, 126.98°E. Its latitude determines how dramatically daylight hours change through the year.
The city uses the Asia/Seoul timezone (GMT+9). 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 Seoul this falls around 12:31 in mid-summer and 12:22 in December, reflecting UTC offset and any DST adjustments.
