Time difference between Philadelphia and Singapore
Philadelphia

Singapore
—
Singapore is 12 hours ahead of Philadelphia right now.
Does the gap change?
The gap isn't fixed. Philadelphia changes its clocks for daylight saving time and Singapore doesn't, so the difference moves during the year:
- From around November 2, 2026: Singapore ahead by 13 hours
- From around March 15, 2027: Singapore ahead by 12 hours
Best time to meet
Normal office hours in Singapore and Philadelphia don't overlap. The most workable window is 7 AM to 10 AM in Philadelphia, which is 7 PM to 10 PM in Singapore, with one side starting early or finishing late.
For a recurring meeting, it's fairest to rotate which city takes the inconvenient slot.
