Time Difference: Tokyo to Karachi

Summary

See the current time in Tokyo (JST, UTC+9) and Karachi (PKT, UTC+5) side by side, with the fixed 4-hour offset, updated live 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 Asia/Karachi time (PKT, UTC+5).
4. The UTC offsets of both cities are compared to calculate the exact hour difference.
5. All three values — Tokyo time, Karachi time, and the offset — refresh every second.
6. Because neither city observes DST, the offset stays at a fixed 4 hours year-round.
