Convert UTC to Bangkok time: when it is 12:00 UTC it is 19:00 in Bangkok in January and 19:00 in July. Bangkok is on UTC+07:00 in standard time, all year. The full 24-hour conversion table is below, and the UTC converter does the conversion live for any date and time.
Try the tool: UTC Converter — convert any UTC time to Bangkok time, or Bangkok time back to UTC, with the offset shown.
Current UTC time and the time in Bangkok
UTC is the world's reference time — it never observes daylight saving, and every other time zone is defined as an offset from it. The table shows four reference instants and what time they are in Bangkok, in January and in July.
| UTC | Bangkok in January | Bangkok in July |
|---|---|---|
| 00:00 | 07:00 | 07:00 |
| 06:00 | 13:00 | 13:00 |
| 12:00 | 19:00 | 19:00 |
| 18:00 | 01:00 | 01:00 |
If the January and July columns are the same, Bangkok's offset does not change — it does not observe daylight saving. If they differ by an hour, that hour is daylight saving, and the Bangkok DST 2026 page gives the exact dates. The world clock shows the current time in Bangkok live, and the time in Bangkok page explains the city's time zone in full.
Bangkok's offset from UTC
Bangkok stays on UTC+07:00 all year — it does not observe daylight saving, so its offset from UTC never changes.
| Period | Offset | In effect |
|---|---|---|
| All year | UTC+07:00 | The offset never changes |
| Right now (11 November 2026) | UTC+07:00 | The offset never changes |
The offset is the only number you need. To convert UTC to Bangkok time, add the offset. To convert Bangkok time to UTC, subtract it. The offset to use is the one in effect on the date you are converting — not today's offset, and not the offset you remember from last summer. The converter on this page's tool does that for you: enter the UTC time and the date, and it looks up the offset from the IANA database for that date.
UTC to Bangkok — full conversion table
Every hour of the day, converted from UTC to Bangkok local time. The January column uses the winter offset (UTC+07:00); the July column uses the summer offset (UTC+07:00). The two columns are identical, because Bangkok does not observe daylight saving.
| UTC | Bangkok (January) | Bangkok (July) |
|---|---|---|
| 00:00 | 07:00 | 07:00 |
| 01:00 | 08:00 | 08:00 |
| 02:00 | 09:00 | 09:00 |
| 03:00 | 10:00 | 10:00 |
| 04:00 | 11:00 | 11:00 |
| 05:00 | 12:00 | 12:00 |
| 06:00 | 13:00 | 13:00 |
| 07:00 | 14:00 | 14:00 |
| 08:00 | 15:00 | 15:00 |
| 09:00 | 16:00 | 16:00 |
| 10:00 | 17:00 | 17:00 |
| 11:00 | 18:00 | 18:00 |
| 12:00 | 19:00 | 19:00 |
| 13:00 | 20:00 | 20:00 |
| 14:00 | 21:00 | 21:00 |
| 15:00 | 22:00 | 22:00 |
| 16:00 | 23:00 | 23:00 |
| 17:00 | 00:00 | 00:00 |
| 18:00 | 01:00 | 01:00 |
| 19:00 | 02:00 | 02:00 |
| 20:00 | 03:00 | 03:00 |
| 21:00 | 04:00 | 04:00 |
| 22:00 | 05:00 | 05:00 |
| 23:00 | 06:00 | 06:00 |
Use the table by finding the UTC hour in the first column and reading across. Note the date change: a UTC time late in the evening is the next day in Bangkok when the offset is positive and large — 22:00 UTC is 05:00 the next day in Bangkok in January — and a UTC time early in the morning is the previous day in Bangkok when the offset is negative. The date matters as much as the time: a meeting at 02:00 UTC on Tuesday is a Monday evening meeting in the Americas.
When the offset changes
The offset never changes. Bangkok does not observe daylight saving, so the table above is right on every day of the year. Thailand sits in the tropics, where day length is nearly constant all year, so daylight saving would bring no benefit. It has not observed it in the modern era. The only thing that changes is the time in the place you are converting from — if that place observes daylight saving, its offset from UTC will move, and the difference between it and Bangkok will move with it.
Bangkok time to UTC
The reverse conversion — Bangkok local time back to UTC — is the same table read backwards. Six examples, for January:
| Bangkok local | UTC (January) | UTC (July) |
|---|---|---|
| 00:00 | 17:00 | 17:00 |
| 06:00 | 23:00 | 23:00 |
| 09:00 | 02:00 | 02:00 |
| 12:00 | 05:00 | 05:00 |
| 15:00 | 08:00 | 08:00 |
| 21:00 | 14:00 | 14:00 |
The reverse table is the one to use when you are telling someone in another time zone when something happens in Bangkok. A flight that departs Bangkok at 09:00 local time departs at 02:00 UTC in January — and that UTC time is what the airline's systems, the air traffic controllers and the arrival airport all use. The flight time calculator works out the arrival time as well, including the date change.
Scheduling with UTC-based teams
Teams that work in UTC — software teams, aviation, shipping, scientific collaborations — schedule in UTC precisely because it never changes. If your team works in UTC, the time in Bangkok is UTC plus UTC+07:00 in January and UTC plus UTC+07:00 in July, and the only question is which of those applies on the meeting date. Put the UTC time in the invitation as well as the local time, and nobody has to convert.
The practical working hours for a UTC-based team and Bangkok are: 09:00–17:00 in Bangkok is 02:00–10:00 UTC in January and 02:00–10:00 UTC in July. A meeting at 14:00 UTC is 21:00 in Bangkok in January — inside the working day — and 21:00 in July. A meeting at 08:00 UTC is 15:00 in Bangkok in January, which is before the working day starts. The meeting planner finds the overlap for any two cities, and the meeting time finder finds it for a whole team.
Frequently asked questions
What time is it in Bangkok when it is 12:00 UTC?
It is 19:00 in January and 19:00 in July. The answer is the same all year, because Bangkok does not observe daylight saving.
What is Bangkok's offset from UTC?
Bangkok is on UTC+07:00 in standard time, all year.
How do I convert UTC to Bangkok time?
Add Bangkok's offset to the UTC time: UTC+07:00 in January, UTC+07:00 in July. The UTC converter does it for any date, and the table above covers every hour.
Does Bangkok observe daylight saving time?
No. Bangkok does not observe daylight saving, so its offset of UTC+07:00 never changes.
What date is it in Bangkok when it is 22:00 UTC?
It is the next day: 22:00 UTC is 05:00 the following day in Bangkok in January (and 05:00 in July). The date change is the part of UTC conversion people most often forget.
What time zone is Bangkok in?
Bangkok is in the IANA time zone Asia/Bangkok, in Thailand. See the time in Bangkok page for the full explanation.
