Time difference between Houston and Singapore
Houston

Singapore
—
Singapore is 13 hours ahead of Houston right now.
Does the gap change?
The gap isn't fixed. Houston 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 14 hours
- From around March 15, 2027: Singapore ahead by 13 hours
Best time to meet
Normal office hours in Singapore and Houston don't overlap. The most workable window is 6 PM to 10 PM in Houston, which is 7 AM to 11 AM 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.
