About Hawaii Standard Time

Hawaii sits at UTC−10 and does not move its clocks at all — it opted out of US daylight saving in 1967. So its gap to the mainland widens by an hour for the eight months the mainland is on daylight time, without Hawaii doing anything.

Cities on this clock: Honolulu.

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

Neither Hawaii Standard Time nor Philippine Time moves its clock relative to the other, so philippine time is 18 hours ahead of hawaii standard time is a rule rather than a fact about one particular year. The hour-by-hour table above holds on every date.

With both zones on their own standard time — daylight saving not in force anywhere — Philippine Time is 18 hours ahead of Hawaii Standard 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 Pacific/Honolulu and Asia/Manila. Nothing is looked up on a server and nothing about your visit is recorded.
