Best Meeting Times: EST and JST
Standard 09:00–17:00 business hours do not overlap between Eastern Time and Japan Standard Time.
With a 14-hour difference, real-time overlap during standard business hours is not possible. The most common approach is for one team to hold a standing early-morning call (07:00–09:00 local) while the other stays late (17:00–19:00 local). Rotate the sacrifice quarterly to distribute meeting burden fairly.
For zero-overlap corridors, we recommend the Meeting Planner's rotation-fairness feature to distribute meeting burden equitably.
Working Across EST and JST
Daylight Saving Time: EST and JST
The US observes Daylight Saving Time. Clocks spring forward 1 hour on the second Sunday in March and fall back on the first Sunday in November. During EDT (UTC−4), the gap to IST narrows by 1 hour.
Japan abolished DST in 1951. JST (UTC+9) has been fixed for over 70 years, making it one of the most stable time zones in the world.
