What is the time difference between Tokyo and Karachi?

Tokyo (JST, UTC+9) is always 4 hours ahead of Karachi (PKT, UTC+5). Neither Japan nor Pakistan observes Daylight Saving Time, so this offset never changes throughout the year.

Does Tokyo observe Daylight Saving Time?

No. Japan abolished DST in 1952 and has not used it since. Tokyo stays on JST (UTC+9) all year.

Does Karachi observe Daylight Saving Time?

No. Pakistan discontinued DST in 2009. Karachi stays on PKT (UTC+5) all year. This means the Tokyo-Karachi gap is a fixed 4 hours with no seasonal change.

What are the best meeting times when calling from Tokyo to Karachi?

Standard business hours (09:00–18:00) overlap well: when it is 13:00–18:00 in Tokyo, it is 09:00–14:00 in Karachi. This gives a solid 5-hour overlap window for joint calls.

Is this tool accurate for scheduling?

Yes. It uses the IANA timezone database embedded in your browser — the same source used by operating systems and calendar apps worldwide. Accuracy depends on your device clock being synchronized via NTP, which most devices do automatically.

PKT stands for Pakistan Standard Time. It is UTC+5, used across all of Pakistan year-round with no Daylight Saving Time.

Summary

This tool displays the live current time in both Tokyo (Asia/Tokyo — JST, UTC+9 year-round, no DST) and Karachi (Asia/Karachi — PKT, UTC+5 year-round, no DST) side by side. Neither city observes Daylight Saving Time, so the offset between them is a constant 4 hours — Tokyo is always 4 hours ahead of Karachi. Use this tool to schedule calls between Japan and Pakistan, coordinate remote teams, or convert meeting times across the two cities.

How it works

Your browser reads the current moment from your device clock.
It converts that moment to Asia/Tokyo time (JST, UTC+9) using the IANA timezone database built into modern browsers.
The same moment is converted to Asia/Karachi time (PKT, UTC+5).
The UTC offsets of both cities are compared to calculate the exact hour difference.
All three values — Tokyo time, Karachi time, and the offset — refresh every second.
Because neither city observes DST, the offset stays at a fixed 4 hours year-round.
