London to Lahore overlap hours and time difference

How do I read this overlap?

1. 1

   Start from the seeded pairing

   The page opens on this city pair with a working pattern already applied, so the first number you see is a realistic one rather than an empty form.

2. 2

   Move the hours to match your teams

   Set the start and end each office actually sits at the desk. The shared block recalculates as you change them, down to fifteen minutes.

3. 3

   Set the meeting date

   Daylight saving is applied for the exact date you pick, not a generic season. That matters in March and again in late October.

4. 4

   Share the URL

   Both cities, both windows, and the date live in the query string. Send the link instead of a screenshot so the other office sees the same thing.

What is the time difference between London and Lahore?

Lahore is four hours ahead of London from late March to late October, when the UK runs on British Summer Time at UTC+1. For the rest of the year the UK returns to Greenwich Mean Time at UTC+0 and Lahore sits five hours ahead.

Pakistan Standard Time is UTC+5 with no daylight saving, so the London side is the only one that moves. When it is 09:00 in London in July, it is 13:00 in Lahore. In January, 09:00 in London is 14:00 in Lahore.

How many hours do London and Lahore share on a normal workday?

Two standard nine to five windows share about four hours during British Summer Time. London 09:00 to 17:00 runs 08:00 to 16:00 UTC and Lahore 09:00 to 17:00 runs 04:00 to 12:00 UTC, so the shared block is 08:00 to 12:00 UTC. In London that reads 09:00 to 13:00 and in Lahore it reads 13:00 to 17:00.

In winter the same windows share three hours. London 09:00 to 17:00 becomes 09:00 to 17:00 UTC, so the overlap tightens to 09:00 to 12:00 UTC, which is 09:00 to 12:00 in London and 14:00 to 17:00 in Lahore.

Either way, no one has to shift. That is unusual and it is the main reason UK clients find Pakistan easier to work with than US clients do.

How do I get more than four hours?

Move the Lahore window later rather than moving London earlier. Lahore 11:00 to 19:00 against London 09:00 to 17:00 gives six hours in summer, and the Pakistan side still finishes at a reasonable time.

If the UK team can start at 08:00, that adds another hour at the front without touching the Pakistan day. Between the two adjustments a six or seven hour block is achievable on this pairing, which is enough to run genuinely collaborative work rather than a handoff.

Do not push London past 18:00 to chase more. The extra hour lands after the Pakistan team has gone home and the overlap does not actually grow.

What should a UK and Pakistan team do with the shared hours?

With four or more hours you can run real collaboration instead of just status. Pair on the hard parts, hold design reviews live, and keep the standup short because you do not need it to carry the whole day.

Put the block on the calendar as a standing window so nobody negotiates it weekly. Use the quiet UK morning before it for deep work and the quiet UK afternoon after it for review and writeups.

When does the London and Lahore overlap change?

Twice a year, in late March and late October, when the UK moves and Pakistan does not. The shared block grows to four hours in spring and shrinks to three in autumn if the local windows stay put.

Set the date in the planner to the week after each switch to see the real number rather than assuming the previous season carries over.
