Meeting Planner
Plan a UTC to JST meeting
Coordinated Universal Time is the global reference time standard with a fixed UTC+00:00 offset. 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 UTC as UTC+00:00 and JST as UTC+09:00. Use the city-based converter when you need automatic seasonal IANA timezone rules for a future date.
