GST to PST

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 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 Gulf Standard 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 11 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 12 hours behind 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 America/Los_Angeles. Nothing is looked up on a server and nothing about your visit is recorded.
