Did You Know?
Sri Lanka moved its legislature to Sri Jayawardenepura Kotte in 1982, making Colombo the commercial capital but not the administrative one. Almost everyone still treats Colombo as the capital, because almost everything else is there.
The clock: Sri Lanka has changed its offset three times since 1996, moving to UTC+6:30, then UTC+6, then back to UTC+5:30 in 2006 to match India.
Colombo lies at 79.9°E. Its time zone, UTC+5:30, is built around the 82.5°E meridian. The 2.6° gap between them means the clock runs roughly 11 minutes ahead of the sun: solar noon arrives at about 12:11 rather than 12:00. The zone holds UTC+5:30 all year — there is no daylight saving here.
The longest day of 2026 is 22 June, with 12h 32m of daylight. The shortest is 22 December, with 11h 43m. The swing between them is 48 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 Colombo the sun comes up earliest on 26 May at 05:53, while the latest sunset waits until 18 July at 18:31. 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 Colombo that civil twilight runs about 21 minutes at the equinox.
Every figure in this section is computed from the city's own latitude, longitude and IANA time zone using NOAA solar algorithms (Spencer, 1971), accurate to about ±2 arcminutes below 65° latitude.
