Reading your clock…
Colombo never changes its clocks
Colombo stays on UTC+05:30 all year round. This is worth being careful about rather than relaxed about: the gap between Colombo and a city that does observe daylight saving still moves twice a year, because the other end moved. A recurring call can drift by an hour without anything changing here at all.
Time difference from Colombo
Where a range is shown, the gap genuinely changes during the year. That is not rounding or hedging — it is two governments moving their clocks on different weekends.

|---|---|---|
| London | 4 hours 30 minutes behind | −5h30 / −4h30 |
| New York | 9 hours 30 minutes behind | −10h30 / −9h30 |

Daylight in Colombo through the year
From about 11.7 hours in December to 12.5 hours in June. This is the part a plain clock leaves out: 17:00 is a bright evening in one month and long dark in another.
| Month | Sunrise | Sunset | Daylight |
|---|---|---|---|
| January | 06:18 | 18:05 | 11h 47m |
| February | 06:16 | 18:13 | 11h 57m |
| March | 06:05 | 18:12 | 12h 7m |
| April | 05:50 | 18:08 | 12h 18m |
| May | 05:43 | 18:11 | 12h 28m |
| June | 05:46 | 18:18 | 12h 32m |
| July | 05:53 | 18:21 | 12h 28m |
| August | 05:55 | 18:14 | 12h 19m |
| September | 05:50 | 17:57 | 12h 7m |
| October | 05:47 | 17:43 | 11h 56m |
| November | 05:53 | 17:40 | 11h 47m |
| December | 06:07 | 17:50 | 11h 43m |
Daylight length is accurate. The clock times of sunrise and sunset assume each city sits at the centre of its time zone, which can put them up to about an hour and a quarter out for places near a zone's edge — Madrid being the standard example. Day length is unaffected.
Questions
About time in Colombo
What time zone is Colombo in?
Colombo uses the IANA time zone Asia/Colombo, a fixed UTC+05:30 with no daylight saving.
Does Colombo observe daylight saving time?
No. Colombo stays on UTC+05:30 all year. That does not mean the gap between Colombo and other cities is fixed, though: when a city that does observe daylight saving changes its clocks, the difference between you and them moves even though nothing changed here.
Why does the time difference to Colombo keep changing?
Because the two places do not change their clocks on the same weekend, and in opposite hemispheres they change in opposite directions. London is a clear example: it sits 5 hours 30 minutes behind, then 4 hours 30 minutes behind across the year rather than one fixed distance.
How much daylight does Colombo get?
Around 12.5 hours at the longest, in June, and about 11.7 hours at the shortest, in December. The table on this page lists sunrise and sunset through the year. Times are calculated from Colombo's latitude of 6.93° and are approximate to within about an hour for cities that sit well away from the centre of their time zone.
