The sun and the clock in Bali (2026)
Bali lies at 115.2°E. Its time zone, UTC+8, is built around the 120°E meridian. The 4.8° gap between them means the clock runs roughly 19 minutes ahead of the sun: solar noon arrives at about 12:19 rather than 12:00. The zone holds UTC+8 all year — there is no daylight saving here.
The longest day of 2026 is 22 December, with 12h 37m of daylight. The shortest is 22 June, with 11h 38m. The swing between them is 59 minutes. Within a few degrees of the equator the length of the day barely moves all year.
The earliest sunrise and the latest sunset do not land on the longest day. In Bali the sun comes up earliest on 15 November at 05:49, while the latest sunset waits until 31 January at 18:47. 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 Bali that civil twilight runs about 21 minutes at the equinox.
