Frequently Asked Questions
What is the time difference between IST and PST?
During standard time, Pacific Standard Time is 13.5 hours behind Indian Standard Time.
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.
What is the difference between PST and PDT?
PST (Pacific Standard Time) is the winter offset at UTC-8, observed from the first Sunday in November through the second Sunday in March. PDT (Pacific Daylight Time) is the summer offset at UTC-7, active when Daylight Saving Time shifts clocks forward by one hour.
Which major cities observe Pacific Standard Time?
Major cities that observe Pacific Standard Time include Los Angeles, San Francisco, Seattle, Las Vegas, Vancouver, and Tijuana.
