JST to EST

About JST to EST

This page converts Japan Standard Time (JST) to Eastern Time (ET). Pick a date and time, and the answer appears at once. Below it, a table shows every hour of that day.

ET is 14 hours behind JST in winter, and 13 hours behind in summer, while the US is on daylight saving time. For example, 9:00 AM JST is 7:00 PM EST (previous day) in winter and 8:00 PM EDT (previous day) in summer.

JST is the time in Tokyo, Osaka, Kyoto, Nagoya and Sapporo — all of Japan. ET is the time in New York, Washington DC, Miami, Atlanta, Boston and Toronto.

The converter uses your browser's own time zone data, so daylight saving is handled for you — always right for the date you pick, in the past or the future.

Eastern Time uses EST (UTC−5) in winter and EDT (UTC−4) in summer. The US clocks go forward on the second Sunday of March and back on the first Sunday of November: March 8, 2026 to November 1, 2026, and March 14, 2027 to November 7, 2027.

Good to know

• EST or ET? Strictly, EST is only the winter time of the US East Coast; in summer it is EDT. Many people say "EST" all year when they mean "East Coast time". This page uses the real clock time for the date you pick, so the answer is right either way.
• Japan is ahead. Tokyo's morning is the US East Coast's evening of the day before — check the day, not only the hour.
• Planning a meeting? Pick the date and time, then add the other cities of the people you meet with. Everyone's time shows in one list.
• The answer comes from your device's time zone data. Nothing is sent anywhere.
