GST to PHT

About Gulf Standard Time

The Gulf runs at a fixed UTC+4, with no clock changes. The half-hour offsets of South Asia start immediately to its east, so the step from Dubai to Karachi is one hour but the step from Dubai to Mumbai is an hour and a half.

Cities on this clock: Dubai, Abu Dhabi, Baku, Tbilisi.

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 Gulf Standard Time nor Philippine Time moves its clock relative to the other, so philippine time is 4 hours ahead of gulf 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 4 hours ahead of Gulf 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 Asia/Dubai and Asia/Manila. Nothing is looked up on a server and nothing about your visit is recorded.
