Time Difference: Tokyo to Miami

Summary

See the current time in Tokyo and Miami side by side, with the live UTC offset between JST (UTC+9) and EST/EDT, updated every second.

How it works

1. Your browser reads the current moment from your device clock.
2. It converts that moment to Asia/Tokyo time (JST, UTC+9) using the IANA timezone database built into modern browsers.
3. The same moment is converted to America/New_York time (EST or EDT depending on the season).
4. The UTC offsets of both cities are compared to calculate the exact hour difference.
5. All three values — Tokyo time, Miami time, and the offset — refresh every second.
6. When Miami switches between EST and EDT, the displayed offset adjusts automatically from 14 to 13 hours.
