Meeting Planner

Plan a EDT to JST meeting

Eastern Daylight Time is the UTC-04:00 daylight-saving offset used in parts of eastern North America. Japan Standard Time is the fixed UTC+09:00 time used throughout Japan and does not observe daylight saving time.

For meetings, begin with the shared business-hours window above. Confirm the date with every participant because abbreviations such as EST, EDT, BST, and CEST describe specific standard or daylight offsets rather than an automatically changing regional clock.

This converter treats EDT as UTC-04:00 and JST as UTC+09:00. Use the city-based converter when you need automatic seasonal IANA timezone rules for a future date.
