Busan lies at 129.1°E. Its time zone, UTC+9, is built around the 135°E meridian. The 5.9° gap between them means the clock runs roughly 24 minutes ahead of the sun: solar noon arrives at about 12:24 rather than 12:00. The zone holds UTC+9 all year — there is no daylight saving here.
The longest day of 2026 is 22 June, with 14h 32m of daylight. The shortest is 22 December, with 9h 47m. The swing between them is 4h 45m. This is the latitude band where the difference between summer and winter evenings is most obvious.
The earliest sunrise and the latest sunset do not land on the longest day. In Busan the sun comes up earliest on 13 June at 05:08, while the latest sunset waits until 30 June at 19:42. The equation of time is what separates them: the Earth's elliptical orbit and axial tilt move solar noon back and forth by several minutes over the year.
The sky stays usably light for a while after the sun goes down. In Busan that civil twilight runs about 25 minutes at the equinox, stretching to 30 minutes at the solstice.
