How many hours is Tokyo ahead of Bangkok?

Tokyo (JST, UTC+9) is always exactly 2 hours ahead of Bangkok (ICT, UTC+7). Neither Japan nor Thailand observes Daylight Saving Time, so this offset never changes throughout the year.

Does Thailand observe Daylight Saving Time?

No. Thailand abolished Daylight Saving Time in 1985. ICT (Indochina Time) is always UTC+7 year-round with no seasonal clock changes.

Does Japan observe Daylight Saving Time?

No. Japan abolished Daylight Saving Time in 1952. JST (Japan Standard Time) is always UTC+9 year-round.

What are the business hours overlap between Tokyo and Bangkok?

Tokyo business hours are roughly 09:00–18:00 JST, which corresponds to 07:00–16:00 ICT in Bangkok. This gives a solid 7-hour overlap during normal working hours, making Tokyo-Bangkok one of the easier Asia-Pacific pairs to coordinate.

Is the clock accurate?

Yes, as long as your device clock is synchronized (most modern devices sync automatically via NTP). The timezone conversions use the IANA database built into your browser.

What is the time in Bangkok when Tokyo is at noon?

When it is 12:00 noon JST in Tokyo, it is 10:00 ICT in Bangkok — always 2 hours earlier, every day of the year.
