It is 4:16 pm in Asia/Colombo
Asia/Colombo is the IANA identifier for the time zone of Colombo in Sri Lanka. It is running at UTC+5:30 right now, with no letter abbreviation in common use, and the local date is Friday, September 25, 2026. The zone never moves its clocks.
What time is it in Asia/Colombo right now
4:16 pm on Friday, September 25, 2026, as this page was served, which in 24 hour form is 16:16. The clock above ticks on from there in your own browser. The offset is 5 hours and 30 minutes ahead of UTC. Half hour offsets catch out code that stores a zone as an integer number of hours, and they are the reason a UTC timestamp converted here lands on :30 or :00 depending on where it started.
1 other zone reads UTC+5:30 at this instant: Asia/Kolkata. They agree on the clock now and need not agree in six months, because each one carries its own daylight saving rule.
The UTC offset of Asia/Colombo
An offset of UTC+5:30 names the meridian 82.5 degrees east. Colombo, Sri Lanka actually sits at 79.86 degrees east, which is 2.6 degrees west of it, so the sun there runs about 11 minutes behind the clock before daylight saving is even considered. Zone boundaries are drawn by borders and by convenience, not by longitude, and this is the size of the gap that produces.
Because this zone never moves its clocks, UTC+5:30 is the answer on every day of the year. That makes it an easy zone to schedule against, with the caveat that the other end of the call may still be moving its own clocks, so the gap between the two changes even though nothing changed here.
Daylight saving in Asia/Colombo
Asia/Colombo does not observe daylight saving. It sits at UTC+5:30 in January and reads UTC+5:30 again in July, so a gap worked out against it today is still right in six months. It did move them once: the sampling below shows a summer offset as late as 2006, and the practice has since been dropped.
The database holds no clock change for Asia/Colombo in 2025, 2026 or 2027, so there is no transition table to print. The offset shown at the top of this page is the offset on every date in those three years.
How the offset of Asia/Colombo has changed since 1970
Read on 1 January and 1 July of each year, which is the cheapest pair of samples that shows both the winter offset and whether the clocks moved that summer. The zone has passed through 5 distinct eras in that time and has used 3 different offsets: UTC+5:30, UTC+6, UTC+6:30. Its current behaviour has held since 2007. A rule change that began and ended between July and the following January is invisible to this sampling, so the table is a shape rather than a complete edit history.
| Years | 1 January | 1 July | Behaviour |
|---|---|---|---|
| 1970 to 1995 | UTC+5:30 | UTC+5:30 | one offset all year |
| 1996 | UTC+5:30 | UTC+6:30 | clocks moved, 1 hour apart |
| 1997 to 2005 | UTC+6 | UTC+6 | one offset all year |
| 2006 | UTC+6 | UTC+5:30 | clocks moved, 30 minutes apart |
| 2007 to 2026 | UTC+5:30 | UTC+5:30 | one offset all year |
The last summer in which Asia/Colombo read a different offset from its own January was 2006. Software that still carries a hand-written summer rule for this zone has been wrong every year since.

Cities in the Asia/Colombo time zone
The 11 cities this site covers inside Asia/Colombo, each with a live clock and today's sunrise and sunset worked out from its own coordinate. They share an identifier, so they share a clock reading to the minute, and they do not share a sunrise: that is set by latitude and longitude.

The sun against the clock in Asia/Colombo
Worked out for Colombo, Sri Lanka, the city this site covers inside the zone, at 6.93 degrees north, 79.86 degrees east. The sun rises at 5:59 am and sets at 6:05 pm, giving 12 hours 6 minutes of daylight. Solar noon, the moment the sun is highest, falls at 12:02 pm, which is 2 minutes after clock noon.
That gap is the whole argument about where zone lines belong, in one number. It is made of three things: Colombo, Sri Lanka sitting 2.6 degrees west of the UTC+5:30 meridian, the equation of time, which today runs 8.2 minutes ahead of mean time, and no daylight saving at all, because this zone does not use it. Full sunrise and sunset times for Colombo.
Convert Asia/Colombo to another time zone
The converter is keyed on the abbreviations people type rather than on identifiers. Asia/Colombo is at UTC+5:30 right now, the same reading as IST, so these pages answer the same question for it today. They will diverge if the two zones ever adopt different daylight saving rules, which is exactly why the identifier is the thing worth storing.

- No. It stays at UTC+5:30 all year, and has done since 2007.
- What is the abbreviation for Asia/Colombo?
- There is no English letter abbreviation in common use for this zone, so it is written as its offset, UTC+5:30. That is what every other clock shows for it too.

- Why store Asia/Colombo instead of UTC+5:30?
- Because the offset is an output and the identifier is the input. This zone has one offset today and no guarantee of keeping it, and 1 other zone shares its current reading while carrying different rules. A record storing UTC+5:30 cannot tell them apart; a record storing
Asia/Colombokeeps working through every future rule change.
