Reading your clock…
Bangkok never changes its clocks
Bangkok stays on UTC+07:00 all year round. This is worth being careful about rather than relaxed about: the gap between Bangkok 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.
Same clock, different sky: Chiang Mai share Asia/Bangkok. Sunrise and sunset differ between them because latitude does, even though the clock does not.
Time difference from Bangkok
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.

| New York | 11 hours behind | −12h / −11h |

Daylight in Bangkok through the year
From about 11.3 hours in December to 12.9 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 | 06:28 | 17:54 | 11h 26m |
| February | 06:22 | 18:07 | 11h 45m |
| March | 06:05 | 18:12 | 12h 7m |
| April | 05:44 | 18:14 | 12h 30m |
| May | 05:33 | 18:21 | 12h 48m |
| June | 05:34 | 18:30 | 12h 56m |
| July | 05:42 | 18:32 | 12h 50m |
| August | 05:48 | 18:20 | 12h 32m |
| September | 05:49 | 17:58 | 12h 9m |
| October | 05:52 | 17:38 | 11h 46m |
| November | 06:03 | 17:30 | 11h 27m |
| December | 06:19 | 17:38 | 11h 19m |
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 Bangkok
What time zone is Bangkok in?
Bangkok uses the IANA time zone Asia/Bangkok, a fixed UTC+07:00 with no daylight saving. The same zone covers Chiang Mai.
Does Bangkok observe daylight saving time?
No. Bangkok stays on UTC+07:00 all year. That does not mean the gap between Bangkok 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 Bangkok 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 7 hours behind, then 6 hours behind across the year rather than one fixed distance.
How much daylight does Bangkok get?
Around 12.9 hours at the longest, in June, and about 11.3 hours at the shortest, in December. The table on this page lists sunrise and sunset through the year. Times are calculated from Bangkok's latitude of 13.76° and are approximate to within about an hour for cities that sit well away from the centre of their time zone.
