About This Time Conversion

This page converts the local time between Tokyo, Japan (timezone Asia/Tokyo, currently ++9, GMT+9) and Islamabad, Pakistan (timezone Asia/Karachi, currently ++5, GMT+5). TZSync uses the IANA timezone database so conversions always account for Daylight Saving Time, half-hour offsets such as India (UTC+5:30), and quarter-hour offsets such as Nepal (UTC+5:45).

When it is daytime in Tokyo, the clock in Islamabad reads a different hour, and possibly a different calendar day. Drag the time slider on this page to find an overlap where both cities are inside typical working hours (9 AM – 5 PM local time) — that overlap is your best window for meetings, calls, and collaboration between Tokyo and Islamabad.
