Time difference between Philadelphia and Tokyo
Philadelphia

Tokyo
—
Tokyo is 13 hours ahead of Philadelphia right now.
Does the gap change?
The gap isn't fixed. Philadelphia changes its clocks for daylight saving time and Tokyo doesn't, so the difference moves during the year:
- From around November 2, 2026: Tokyo ahead by 14 hours
- From around March 15, 2027: Tokyo ahead by 13 hours
Best time to meet
Normal office hours in Tokyo and Philadelphia don't overlap. The most workable window is 6 PM to 10 PM in Philadelphia, which is 7 AM to 11 AM in Tokyo, with one side starting early or finishing late.
For a recurring meeting, it's fairest to rotate which city takes the inconvenient slot.
