PST to PHT

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.

About Philippine Time

The Philippines is a fixed UTC+8. It is a heavily quoted zone in outsourcing schedules, which is why the pairs from it to North America are among the most searched on this site.

Cities on this clock: Beijing, Shanghai, Guangzhou, Shenzhen, Chongqing, Taipei, Hong Kong, Singapore.

Watch out: Philippine Standard Time is often written PST locally — the same letters as US Pacific Standard Time, which is sixteen hours behind it.

How the difference is worked out

The gap between Pacific Time and Philippine Time is not one number. The two zones change their clocks on different dates, so for part of the year the difference is 15 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 — Philippine Time is 16 hours ahead of Pacific 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 America/Los_Angeles and Asia/Manila. Nothing is looked up on a server and nothing about your visit is recorded.
