What PKT and CST Actually Are
PKT — Pakistan Standard Time
Karachi, Lahore, Islamabad, Faisalabad. Standing at UTC+5:00 as written, and the region does not change its clocks, so that offset holds all year.
Pakistan tried daylight saving in 2008 and 2009 to ease electricity shortages, then dropped it after public objection.
CST — Central Standard Time
Chicago, Houston, Dallas, Mexico City, Winnipeg. Standing at UTC-6:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, November 1, 2026, to CST. CST also stands for China Standard Time (UTC+8) and Cuba Standard Time (UTC-5). This page covers the North American one.
Saskatchewan sits inside the Central zone but never changes its clocks, so it matches CST in winter and its neighbors' MDT in summer.
What This Means in Practice
The date changes mid-working-day
For 1 of the eight hours in a normal PKT working day, the equivalent CST time falls on a different calendar date. Anything scheduled in that stretch needs the date checked as well as the time, or a Tuesday call quietly becomes a Wednesday one at the other end.
This gap is not fixed
CST changes its clocks and PKT does not, so the difference between them moves by an hour twice a year. A recurring meeting set now will drift for one side from Sunday, November 1, 2026 unless someone resets it.
Nearly opposite sides of the clock
At 10 hours apart, one side's morning is the other side's night. Handing work over at the end of a shift usually beats trying to get both parties in the same call.

Frequently Asked Questions
What is the time difference between PKT and CST?
CST is 10 hours behind PKT. That is the live figure. Taken strictly as written, the gap between PKT and CST is 11 hours — the two differ because at least one of these regions is currently on daylight saving.
What is 9:00 AM PKT in CST?
9:00 AM PKT is 11:00 PM the previous day CST.
What are the best hours to schedule a call between PKT and CST?
Standard business hours in these two zones do not overlap at all, so one side has to work outside the 9-to-5. The most workable window is 5:00 PM to 10:00 PM PKT, which is 7:00 AM to 12:00 PM CST.
Does the difference between PKT and CST change during the year?
Yes. CST observes daylight saving and PKT does not, so the gap shifts by an hour at least twice a year. The next clock change is on Sunday, November 1, 2026.
Does CST always mean Central Standard Time?
CST also stands for China Standard Time (UTC+8) and Cuba Standard Time (UTC-5). This page covers the North American one.
