JST to EST
JST and EST explained
Japan Standard Time (JST) is UTC+9 all year: the whole of Japan has no daylight saving time.
Eastern Time uses EST (UTC−5) as standard time and EDT (UTC−4) during daylight saving time, from the second Sunday in March to the first Sunday in November; the clocks change at 2am local time. It covers the eastern US and Canada, including New York, Washington DC, Miami, Atlanta and Toronto. People often say "EST" all year, but EST is strictly the winter name: during daylight saving time the eastern US is on EDT.
The difference across the year
ET compared with JST:
- 13 hours behind (JST and EDT) from the second Sunday in March to the first Sunday in November
- 14 hours behind (JST and EST) from the first Sunday in November to the second Sunday in March
ET changes its clocks and JST doesn't, so the gap changes during the year. The converter above uses the rules for the date you pick.
