Shared working hours
They do not overlap at all. A 09:00–17:00 working day in Indochina Time ends 2 hours before the Pacific Time one begins, so any live call sits outside somebody's working hours.
The shortest reach is the edges: early morning in ICT against late evening in PST, or the other way round.
When the difference changes
The two zones move their clocks on different dates, so the gap takes more than one value. These are the stretches of 2026:
| Dates | PST is | Why |
|---|---|---|
| 1 January – 8 March | 15 hours behind | — |
| 8 March – 1 November | 14 hours behind | Pacific Time clocks go forward one hour |
| 1 November – 1 January | 15 hours behind | Pacific Time clocks go back one hour |
Dates are Indochina Time local dates for 2026. Transition dates move by a few days from year to year; the rule each country follows does not.
About Indochina Time
Indochina Time is a fixed UTC+7 shared by Thailand, Vietnam, Cambodia and Laos. Nothing in the zone changes its clock, so every gap on this page holds for the whole year.
Cities on this clock: Jakarta, Bangkok, Ho Chi Minh City, Hanoi, Phnom Penh.
About Pacific Time
Pacific Time runs the length of the west coast, from British Columbia to the Mexican border. It sits at UTC−8 as PST for about four months of the year and at UTC−7 as PDT for the other eight, moving on the second Sunday in March and the first Sunday in November — dates set by US federal law that the Canadian Pacific provinces follow so the border stays on one clock.
Cities on this clock: Los Angeles, San Diego, San Jose, Seattle, Portland, Las Vegas, Vancouver.
How the difference is worked out
The gap between Indochina Time and Pacific Time is not one number. The two zones change their clocks on different dates, so for part of the year the difference is 14 hours and for the rest it is something else — the table above lists each stretch of 2026 with the date it starts and which country's clocks moved.
With both zones on their own standard time — daylight saving not in force anywhere — Pacific Time is 15 hours behind Indochina Time. That figure never changes; everything else on this page follows from it plus whichever clocks have moved.
Every figure here comes from the IANA time zone database via your browser's own Intl engine, using the zone ids Asia/Bangkok and America/Los_Angeles. Nothing is looked up on a server and nothing about your visit is recorded.
Is PST ahead of or behind ICT?
Pacific Time is 14 hours behind Indochina Time for 238 days of the year, and takes 2 different values across the year. The gap moves because the two zones change their clocks on different dates — on 8 March, Pacific Time clocks go forward one hour; on 1 November, Pacific Time clocks go back one hour (dates for 2026).
What time is 9 AM ICT in PST?
9:00 AM ICT is 7:00 PM PST the previous day for most of the year — see the table above for the 3 stretches of 2026 the gap holds different values.
