JST to EST converter

Japan Standard Time is UTC+9 all year, so the only thing that changes on this pair is New York. Tokyo is 13 hours ahead of the east coast during EDT and 14 hours ahead during EST.

Japan has no daylight saving, so JST is UTC+9 all year. Most people who search "EST" mean the local clock time on the US east coast. That clock is on EST (UTC-5) in winter and EDT (UTC-4) in summer; in 2026 EDT runs from March 8 until clocks go back on November 1. The converter above follows the real clock for the date you pick, so you do not have to remember which half of the year it is. The live line and the table use the same rules.

A 9:00 AM morning in Tokyo is 8:00 PM the previous evening in New York during EDT. Japanese business hours and US business hours do not overlap on a working day, so cross-ocean calls are either very early or very late for one side.

When scheduling a livestream or a game event in JST for a US audience, remember the Japan date is a day ahead of the US date through the Japanese morning and early afternoon.
