About Tokyo's time zone

Tokyo operates on Japan Standard Time (JST, UTC+9) year-round. Japan abolished daylight saving time in 1952 and has not observed it since, making Tokyo's offset constant throughout the year. JST is one of the few major time zones with no DST, which simplifies scheduling across time zones. Tokyo is 14 hours ahead of New York (EST) and 9 hours ahead of London (GMT) in winter.

Did you know? Japan's refusal to adopt daylight saving time is partly cultural — the concept of changing clocks twice a year was introduced during the US occupation after WWII but was so unpopular it was abolished. The country values consistency and the idea of 'wasting' daylight by sleeping in goes against Japan's work ethic.
