Time difference between San Francisco and Singapore
Singapore is 15 hours ahead of San Francisco from March to October, and 16 hours from November to March, because San Francisco changes its clocks and Singapore does not.
The two offsets
| City | Zone | 15 January | 15 July |
|---|---|---|---|
| San Francisco · United States | America/Los_Angeles | UTC-8 | UTC-7(DST) |
| Singapore · Singapore | Asia/Singapore | UTC+8 | UTC+8 |
When both are at work
Working hours taken as 9:00–18:00 in each city. The grid below uses the winter offsets. In summer the gap widens and no hour suits both.
