About GST and PST
GST (Gulf Standard Time) covers UAE and Oman and is anchored to the IANA zone Asia/Dubai. It does not observe daylight saving time — the offset stays fixed all year.
PST (Pacific Time (US)) covers USA and Canada via America/Los_Angeles. It observes daylight saving time, so the gap between these two zones shifts twice a year.
Because at least one of these zones uses DST, the time difference between GST and PST is not constant — it shifts by an hour during the spring and autumn DST transitions. The hour grid below recomputes the difference for any specific date you click, using the IANA rules baked into your browser.
