Time in Colombo Now — Current Local Time. Colombo is on UTC+05:30 right now — Colombo stays on UTC+05:30 all year — it does not observe daylight saving, so its offset from UTC never changes. The current local time, date and daylight saving status are shown live by the world clock, which is worked out from the IANA time zone database (Asia/Colombo), not from a printed table.

What time is it in Colombo now?
The world clock shows the current time in Colombo live — the time, the date and the day of the week — updated every second from your device's clock and the IANA time zone database. It is the time in the Asia/Colombo zone, which covers Colombo and the surrounding region. The clock does not use a fixed offset: it asks the database what the offset is on today's date, so it is right whether daylight saving is in effect or not. That matters more than it sounds, because Colombo's offset never changes, which is one reason the time in Colombo is easy to remember.
If you need the time in Colombo for a meeting or a flight, use the live clock rather than a remembered offset. The remembered offset is right most of the year and wrong for a few weeks — the weeks when Colombo is on the same time it is always on, while the place you are calling from has just changed its clocks. The time zone converter handles the date as well as the cities, so it is right on the awkward dates too.
Colombo's UTC offset
Colombo stays on UTC+05:30 all year — it does not observe daylight saving, so its offset from UTC never changes.
| Period | Offset | In effect |
|---|---|---|
| All year | UTC+05:30 | The offset never changes |
| Right now (11 November 2026) | UTC+05:30 | The offset never changes |
The offset is the whole story for conversions. To get the time in Colombo from UTC, add the offset: when it is 12:00 UTC, it is 17:30 in Colombo in January and 17:30 in July. To go the other way, subtract it. The UTC converter does the arithmetic for any hour, and the UTC to Colombo page has the full 24-hour conversion table for this city.
Daylight saving in Colombo
Colombo does not observe daylight saving time, and its offset never changes. Sri Lanka sits close to the equator, where day length is nearly constant all year, so daylight saving has never been used. That makes Colombo one of the easiest cities in the world to schedule with: the time difference between Colombo and anywhere else only changes when the other place changes its clocks. The Colombo DST 2026 page explains the history, and the daylight saving checker confirms the status for any zone.
Colombo working hours in other cities
The table below converts Colombo's working day — 09:00 to 17:00 local time — into the time in four reference points: UTC, New York, London and Tokyo. It is the table to use when you are working out whether someone in Colombo is at their desk.
January (northern winter) — when it is the time in the first column in Colombo, it is the time shown in each other city.
| Time in Colombo | UTC | New York | London | Tokyo |
|---|---|---|---|---|
| 09:00 | 03:30 | 22:30 | 03:30 | 12:30 |
| 12:00 | 06:30 | 01:30 | 06:30 | 15:30 |
| 15:00 | 09:30 | 04:30 | 09:30 | 18:30 |
| 17:00 | 11:30 | 06:30 | 11:30 | 20:30 |
July (northern summer) — when it is the time in the first column in Colombo, it is the time shown in each other city.
| Time in Colombo | UTC | New York | London | Tokyo |
|---|---|---|---|---|
| 09:00 | 03:30 | 23:30 | 04:30 | 12:30 |
| 12:00 | 06:30 | 02:30 | 07:30 | 15:30 |
| 15:00 | 09:30 | 05:30 | 10:30 | 18:30 |
| 17:00 | 11:30 | 07:30 | 12:30 | 20:30 |
Read the table from left to right: find the time in Colombo, then read across to see what time it is in each other city. If the January and July tables differ, the difference is daylight saving — one or more of the cities has changed its clocks between the two dates. The meeting planner does the same conversion for any two cities and any date, and the meeting time finder finds the hours when everyone is available.
Best time to call Colombo
The best windows to call Colombo — the hours when Colombo is in its working day and New York, London and Tokyo are most likely to be awake — are 13:00–24:00 Colombo time, 00:00–04:00 Colombo time (January, when the offsets are as shown in the table above). These are the hours when at least two of the three hubs are between 07:00 and 22:00 local time, so the call is inside the working day in Colombo and at a reasonable hour for the other side. Outside these windows, the call is either before the working day in Colombo or in the middle of the night somewhere else.
As a rule of thumb, the kindest time to call Colombo from the United States is late morning in New York, which is the afternoon or evening in Colombo for most of the world east of the Atlantic — and the kindest time from Europe is mid-morning in London, which is late morning or afternoon in Colombo for most of Asia. The worst time to call is the hour that is 03:00 somewhere: check the tables above before you dial.
About Colombo and its time zone
Colombo is on Sri Lanka Standard Time, UTC+05:30, all year — the same time as India. Sri Lanka sits close to the equator, so daylight saving has never been used.
Colombo is in the Asia region, and its IANA time zone is Asia/Colombo. That name is the identifier computers use: when your phone, your calendar or this website works out the time in Colombo, it looks up Asia/Colombo in the IANA Time Zone Database and applies the rules for that zone on the date you asked about. The rules include the standard offset, the daylight saving dates and the whole history of changes — which is why the answer is right even for dates in the past, when the rules were different.
The practical consequence is that the time in Colombo is not a fixed number. It is a single number, all year, which is the simplest case in time-zone work. The time in Colombo is UTC+05:30 on every day of the year, and the only thing that changes is the time in the place you are calling from. The time zone list shows every zone in the database with its current offset, and the guides explain how the system works.
Colombo compared with the world's major cities
When it is 12:00 in Colombo, it is:
| City | January | July |
|---|---|---|
| New York | 01:30 | 02:30 |
| London | 06:30 | 07:30 |
| Paris | 07:30 | 08:30 |
| Dubai | 10:30 | 10:30 |
| Mumbai | 12:00 | 12:00 |
| Singapore | 14:30 | 14:30 |
| Tokyo | 15:30 | 15:30 |
| Sydney | 17:30 | 16:30 |
The January and July columns differ wherever one of the cities observes daylight saving and the other does not, or where they change their clocks on different dates.
How to convert Colombo time
Three worked examples, all for January, when Colombo is on UTC+05:30: 09:00 in Colombo is 03:30 UTC, 03:30 in London and 22:30 in New York. 12:00 in Colombo is 06:30 UTC and 15:30 in Tokyo. 17:00 in Colombo — the end of the working day — is 11:30 UTC and 06:30 in New York. In July, when Colombo is on UTC+05:30, add or subtract the difference between the two offsets — there is none, because the offset does not change — from each of those answers.
