Daylight saving time note
Singapore and Los Angeles do not change their clocks on the same date. Between November 1, 2026 and March 14, 2027 the difference is 16 hours ahead of Los Angeles — because Los Angeles changes its clocks for daylight saving time while Singapore keeps the same time all year.
For the rest of the year the difference holds steady at 15 hours. Every time on this page is computed from the IANA database at the moment you load it, so the tables above already account for whichever side has switched.
Why the time difference exists
The clock in Singapore is anchored to UTC+8 standard time; Los Angeles works from UTC-8 standard time. Only Los Angeles shifts for daylight saving; Singapore stays put, which nudges the difference by an hour twice a year. Los Angeles sits roughly 14,100 km to the northeast of Singapore.
Expect roughly a 8 hours forward adjustment travelling from Singapore to Los Angeles. The direct distance works out to roughly 17½ hours in the air. Line up a shared window before you call and the rest is easy.
