Daejeon is located at 36.35°N, 127.38°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 Daejeon this falls around 12:29 in mid-summer and 12:20 in December, reflecting UTC offset and any DST adjustments.
