Frequently Asked Questions
What is the time difference between PDT and IST?
During standard time, Indian Standard Time is 12.5 hours ahead of Pacific Daylight Time.
When does PDT start and end?
PDT begins on the second Sunday in March at 02:00 local time, when clocks spring forward one hour from PST (UTC-8) to PDT (UTC-7). It ends on the first Sunday in November at 02:00 local time, when clocks fall back to PST. In 2026, PDT runs from March 8 through November 1 — covering the majority of the calendar year.
Is PDT the same as PST?
PDT and PST are two phases of the same Pacific Time zone, not two separate zones. PST (Pacific Standard Time) is the winter offset at UTC-8, observed from early November through mid-March. PDT (Pacific Daylight Time) is the summer offset at UTC-7, active during Daylight Saving Time — meaning Los Angeles, Seattle, and Vancouver run one hour ahead of their winter clock for approximately eight months of every year.
Does India observe Daylight Saving Time (DST)?
India does not observe Daylight Saving Time and has not done so since 1945. IST remains fixed at UTC+5:30 every day of the year, meaning the offset between India and any DST-observing country shifts by one hour twice annually when those countries change their clocks.
Why does IST have a 30-minute offset?
India chose the 82.5° East meridian — which passes through Mirzapur in Uttar Pradesh — as its central reference longitude, as it bisects the subcontinent geographically. That meridian sits exactly 5 hours and 30 minutes ahead of the Prime Meridian in Greenwich, producing the UTC+5:30 offset that has defined IST since 1906.
