How to use
Open the live clock
The page shows current date and time for Asia/Bangkok from your browser.
Refresh if needed
Use Refresh to re-read the clock; the display also updates about once per second.
Plan with a fixed offset
Bangkok stays on ICT (UTC+7) all year — only the other city’s DST (if any) can change the difference.

Bangkok / Thailand Time specification
Version 1.0.1 · Engine tested
- Engine tested 3 published cases
- Named expert review Not performed
- Calculation version 1.0.1
- Definition
- Bangkok and all of Thailand use Indochina Time (ICT) on the IANA zone Asia/Bangkok. The offset is UTC+07:00 year-round — Thailand does not observe Daylight Saving Time, so clocks never spring forward or fall back.
- What it calculates
- Current local date and time in the Asia/Bangkok time zone (Bangkok / Thailand / Indochina Time).
- Inputs
- None — uses the device clock and the IANA zone Asia/Bangkok
- Outputs
- Local time (24-hour style from the browser formatter)
- Local calendar date
- Formula
Display = Intl.DateTimeFormat with timeZone Asia/Bangkok- Assumptions
- Device clock and OS timezone database are reasonably correct.
- Covers all of Thailand; ICT is also used elsewhere in the region under other IANA ids.
- Runs locally in the browser; no server round-trip for the clock.
- Units
- Civil local time (hours, minutes, seconds)
- UTC offset ICT +7 (fixed)
- Boundary conditions
- No DST transitions — every civil hour occurs once per day
- Difference to DST-observing cities changes when those cities change clocks
- Example
- 12:00 UTC → 19:00 Asia/Bangkok
- Validation cases
3 published on this page
- UTC 12:00 → 19:00 Asia/Bangkok
- Same instant as Asia/Singapore → Bangkok is 1 hour earlier
- Same instant as Asia/Kolkata → Bangkok is 1 hour 30 minutes later
- Specification basis

Background
Interpretation and common distinctions.
Current time in Bangkok, Thailand
This page shows a live local clock for Bangkok and all of Thailand, using the IANA zone Asia/Bangkok. Time is read from your browser with that zone applied — the same civil time used nationwide.
Thailand has one time zone. Scheduling a call with Chiang Mai or Phuket uses the same clock as Bangkok.
Indochina Time (ICT)
| Name | Abbreviation | UTC offset | DST |
|---|---|---|---|
| Indochina Time | ICT | UTC+7 | None |
Bangkok stays on UTC+7 year-round. Prefer UTC+7 or Asia/Bangkok when precision matters: abbreviations like “CST” are reused in unrelated regions.
ICT is also the everyday name for UTC+7 in Vietnam, Cambodia, Laos, and Western Indonesia (WIB). This tool specifically follows Asia/Bangkok.
No Daylight Saving Time
Thailand does not observe DST and historically has not switched clocks for summer time. There is no spring-forward or fall-back date to remember for Bangkok itself.
When you compare Bangkok to London, New York, or Los Angeles, only their seasonal changes move the difference — Bangkok’s offset stays fixed.
How Bangkok time compares
Fixed neighbors (no DST on either side):
- Singapore, Hong Kong, Beijing / China (UTC+8): Bangkok is 1 hour behind.
- Tokyo / Seoul (UTC+9): Bangkok is 2 hours behind.
- India (IST) (UTC+5:30): Bangkok is 1 hour 30 minutes ahead.
- UTC: Bangkok is always 7 hours ahead.
Against DST-observing zones (approximate):
- London: 7 hours ahead of GMT; 6 hours ahead of BST.
- New York: about 12 hours ahead of EST; 11 hours ahead of EDT.
- Los Angeles: about 15 hours ahead of PST; 14 hours ahead of PDT.
UTC vs GMT
For everyday scheduling, UTC and GMT both mean offset +0. UTC is the modern atomic-clock standard; this clock is defined as UTC+7. Example: noon UTC is 19:00 in Bangkok.

Frequently asked questions
Key distinctions behind the calculation.
What time zone is Bangkok in?
Bangkok uses Indochina Time (ICT). The IANA identifier is Asia/Bangkok. The offset is UTC+7 all year.
Does Thailand observe Daylight Saving Time?
No. Thailand has never used DST. Clocks in Bangkok stay on ICT (UTC+7) with no spring-forward or fall-back.
Is all of Thailand on the same time?
Yes. Thailand has a single national time zone. Bangkok, Chiang Mai, Phuket, and the rest of the country share Asia/Bangkok / ICT.
What is Indochina Time (ICT)?
ICT is the common name for UTC+7 used in Thailand and neighboring countries such as Vietnam, Cambodia, and Laos, as well as Western Indonesia (WIB). This clock uses Asia/Bangkok specifically.
How does Bangkok time compare to Singapore or Hong Kong?
Singapore, Hong Kong, and Beijing/China stay on UTC+8 year-round, so Bangkok is always one hour behind those cities.
How does Bangkok compare to London or New York?
Against UTC+0 (GMT), Bangkok is 7 hours ahead. When the UK is on BST (UTC+1), the lead is 6 hours. Against U.S. Eastern Time, Bangkok is typically 12 hours ahead in winter (EST) and 11 hours ahead in summer (EDT).
Why use Asia/Bangkok instead of “ICT”?
IANA zone IDs encode the correct offset for computers. Abbreviations can be reused or misread. This clock uses Asia/Bangkok so the browser applies the official fixed UTC+7 rule.
What is UTC?
Coordinated Universal Time (UTC) is the global time standard. Zone offsets are written as hours ahead of (+) or behind (−) UTC. Bangkok is always UTC+7.
