Frequently Asked Questions
What is the time difference between IST and PKT?
During standard time, Pakistan Standard Time is 0.5 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.
Does Pakistan observe Daylight Saving Time?
Pakistan does not observe Daylight Saving Time and has maintained a permanent UTC+5:00 offset since abandoning its last seasonal DST trial in 2009. The fixed offset means that the time difference between Pakistan and any DST-observing partner country shifts by one hour twice annually when those countries change their clocks — but PKT itself never moves.
What is the time difference between PKT and India's IST?
Indian Standard Time (IST) is exactly 30 minutes ahead of Pakistan Standard Time (PKT) at all times, since neither country observes Daylight Saving Time. A meeting scheduled at 10:00 PKT in Karachi or Lahore falls at 10:30 IST in Mumbai or New Delhi — a fixed, permanent relationship that never shifts seasonally.
