London and Karachi: time difference and best meeting times

Karachi is 4 hours ahead of London for most of 2026. With a 9:00 to 17:00 working day in both places, you share up to 4 hours each day, which is enough for a full block of meetings.

Shared working hours

The table assumes a working day of 9:00 to 17:00 in both cities. Times are local to each city. January and July show the two ends of the year, because daylight saving changes the picture.

SeasonTime differenceShared hoursShared window in LondonShared window in Karachi
January (15 January) 5 hours 3 hours 09:00 to 12:00 14:00 to 17:00
July (15 July) 4 hours 4 hours 09:00 to 13:00 13:00 to 17:00

Put recurring meetings inside the shared window, and use the rest of the day for focused work. A good default slot is 10:30 to 11:30 in London, which is 14:30 to 15:30 in Karachi. With this much overlap you can alternate which side sits closer to the edge of their day, so one team is not always the one meeting early.

With a longer day, 08:00 to 18:00

If people on both sides can start an hour earlier and finish an hour later, the shared time becomes 5 hours in January and 6 hours in July. In January that is 08:00 to 13:00 in London, which is 13:00 to 18:00 in Karachi. In July it is 08:00 to 14:00 in London, which is 12:00 to 18:00 in Karachi.

Tips for teams in London and Karachi

  • Name both cities in the invitation, for example "10:30 to 11:30 London / 14:30 to 15:30 Karachi".
  • Check recurring meetings when clocks change. The gap is 5 hours instead of 4 hours for part of the year, so the shared window moves.
  • Keep the shared 3 hours for meetings, and do focused work outside it.
