About these time zones
Japan Standard Time (JST)
Japan Standard Time (JST) is UTC+9 all year across the whole of Japan. Japan has not observed daylight saving time since 1951. JST shares its offset with Korea Standard Time.
Eastern Standard Time (EST)
Eastern Standard Time (EST) is UTC-5. Most places on Eastern Time use EST only in winter; from the second Sunday in March to the first Sunday in November they observe Eastern Daylight Time (EDT, UTC-4). People often write “EST” all year when they mean Eastern Time, so check which one is in effect.
JST to EST FAQs
What time is it in EST when it is 9 AM JST?
On Sunday, September 20, 2026, 9:00 AM JST is 8:00 PM EDT (previous day) in Eastern Time.
How many hours ahead is JST from EST?
It depends on the time of year because of daylight saving time. Now until Nov 1, 2026: Japan Standard Time is 13 hours ahead of Eastern Time (JST → EDT). Nov 1, 2026 – Mar 14, 2027: Japan Standard Time is 14 hours ahead of Eastern Time (JST → EST).
Should I use EST or EDT?
Eastern Time is on EDT (UTC-4) on Saturday, September 19, 2026. Many people write “EST” all year, but strictly EST means Eastern Standard Time (always UTC-5). This converter follows the real local time in Eastern Time, including daylight saving time.
What is the best time for a call between JST and EST?
On Saturday, September 19, 2026, good options are 9:00 AM JST (8:00 PM EDT), 10:00 AM JST (9:00 PM EDT). There is no overlap of 9 AM–5 PM working hours, so these fall early or late for one side.
Does JST change for daylight saving time?
No. JST stays at UTC+9 all year.
Does EST change for daylight saving time?
The region changes: Eastern Time switches between EST and EDT, so conversions depend on the date. EST itself always means UTC-5.
