How to use it
- Enter time in gmt and day in gmt (optional).
- The result appears straight away and updates as you edit.
- Copy the result, or copy a link that keeps the same values to share it.
How it is calculated
PKT time = GMT time + 5 hours, because PKT is UTC+5 and GMT is UTC+0. If the result reaches 24:00 or more, subtract 24 hours and move to the next day; if it drops below 00:00, add 24 hours and move to the previous day.
Example
Inputs: Time in GMT = 22:00, Day in GMT (optional) = Thursday. Result: Time in PKT: 03:00; Day change: Next day (+1); Offset difference (PKT minus GMT): 5 hours.
Limits and caveats
- Fixed offsets are used: GMT = UTC+0 and PKT = UTC+5, whatever the date.
- London leaves GMT for BST (UTC+1) from the last Sunday of March to the last Sunday of October; the tool does not apply that change.
Questions about this tool
What time is 09:00 GMT in PKT?
09:00 GMT is 14:00 PKT on the same day, because PKT is 5 hours ahead of GMT.
Does daylight saving time change the result?
The tool keeps GMT at UTC+0 all year. London leaves GMT for BST (UTC+1) from the last Sunday of March to the last Sunday of October; in that period the gap between London and PKT is 4 hours.
How do I convert PKT back to GMT?
Subtract 5 hours from the PKT time. If the result falls below 00:00, add 24 hours and it is the previous day in GMT.
