Time difference between the UK and Pakistan, and how it trips up bookings

The time difference between UK and Pakistan is four hours in the British summer and five hours in the British winter, with Pakistan always ahead. Pakistan runs on Pakistan Standard Time (PKT), which is UTC+5 all year, and it has not used daylight saving since 2009. The UK moves between GMT (UTC+0) and British Summer Time (UTC+1), so the whole swing comes from the British side. From the last Sunday in March to the last Sunday in October, noon in London is 4pm in Lahore. For the rest of the year, noon in London is 5pm.

That is the number every converter gives you. The trouble is what happens after it. Failed ground bookings from the UK rarely come from bad arithmetic. They come from a pickup typed in the wrong clock, a flight landing after midnight on a date nobody rechecked, or an approval sent into Pakistan’s night. This guide takes those failure points in turn.

The decision summary

• Offset: Pakistan is 4 hours ahead of the UK from late March to late October, and 5 hours ahead from late October to late March.
• Which clock to book in: always Pakistan local time, taken from the arrival line of the ticket, never from a UK calendar entry.
• Which date to book: the arrival date printed on the ticket. Overnight flights from the UK routinely land on the next calendar day.
• When to approve: treat a UK evening as a Pakistani night. Anything that needs a reply from Pakistan should leave your hands before about 5pm UK time.
• Danger weeks: the two weekends when UK clocks change. A recurring meeting, a family call or a saved reminder quietly moves by an hour against Pakistan.

Why the time difference between UK and Pakistan changes twice a year

Pakistan uses a single time zone for the whole country. Pakistan Time is UTC+05:00, identical in Karachi, Lahore, Islamabad and Skardu.

The UK is the moving part. According to GOV.UK’s page on when the clocks change, UK clocks go forward one hour at 1am on the last Sunday in March and go back one hour at 2am on the last Sunday in October. During the summer period the UK is on British Summer Time (UTC+1); the rest of the year it is on Greenwich Mean Time (UTC+0).

For the next few years that gives these switch-over dates, taken from the same GOV.UK page:

Pakistan did experiment with daylight saving. It tried it in 2002 and again during the energy shortages of 2008 and 2009, and dropped it each time after public resistance, as the history of Pakistan Standard Time records. If a device or website shows a UK gap other than 4 or 5 hours, distrust the device.

PKT to BST and PKT to GMT in one line each

• PKT to BST: subtract 4 hours. 9am PKT is 5am BST.
• PKT to GMT: subtract 5 hours. 9am PKT is 4am GMT.
• UK time to Pakistan time: add 4 hours in summer, 5 hours in winter.

Quick conversion table: UK time to Pakistan time

Keep this open while you fill in a booking form. The left column is what your phone says in the UK; the other two columns are what the driver’s phone says in Pakistan.

The rows that matter most are the evening ones. From 7pm in a UK winter, Pakistan has already crossed into the next date. That is where most of the mistakes described below begin.

Rule one: book every pickup in Pakistan local time

A pickup time is an instruction to someone standing in Pakistan. The driver reads it on a Pakistani phone, the airport arrivals screen shows Pakistani time, and the flight’s arrival time on your ticket is already printed in Pakistani time. Airline itineraries normally show each departure in the local time of the airport you leave and each arrival in the local time of the airport you land at, so the arrival line on your ticket needs no conversion at all.

The error happens when a traveller converts a number that was already local: “arrives 06:10” becomes 11:10 because Pakistan is ahead, and the passenger waits five hours. Or a calendar app set to London time shows the landing as 01:10, and that figure goes onto the form.

Three habits prevent both errors:

1. Copy the arrival time and date straight from the airline’s e-ticket or booking page, not from a calendar app, email preview or smartwatch notification.
2. Write “PKT” next to every time in your notes and in any message to the operator. An unlabelled “7:30” invites someone to guess.
3. Give the flight number as well as the time. A flight number lets the operator check the schedule and track changes, which is more reliable than any time you type.

If you are arranging the journey from Britain for the first time, our guide to booking a taxi in Pakistan from the UK covers the rest of the process.

Rule two: the arrival date is usually not the departure date

Add a long flight to the four or five hours Pakistan is ahead, and any evening departure from the UK lands on the following calendar day. This is the single most expensive mistake in UK to Pakistan ground bookings, because a pickup booked for the wrong date is not late by minutes; it is late by 24 hours, or it happened yesterday.

The trap is sharpest for flights that land between midnight and about 6am PKT. The passenger thinks of it as “Tuesday night’s flight”. The ticket says it arrives on Wednesday. A relative in Lahore thinks of it as “Wednesday morning, very early”. All three are describing the same landing, but only one date belongs on a booking form: the arrival date on the ticket.

Our sister company Pilgrim Taxi sees exactly the same confusion with Umrah arrivals into Saudi Arabia and has a useful walk-through on reading back the arrival date and time for a UK-to-Saudi flight; the logic transfers directly to Pakistan, with a different offset.

Worked examples: Heathrow to Islamabad and Lahore arrivals

The examples below are illustrations, not real timetables. The departure times and the eight-hour flight time are assumptions chosen to make the arithmetic clear; your own ticket is the only source that counts. Schedules on UK to Pakistan routes have moved around a great deal in recent years. Pakistan International Airlines was barred from flying to the UK in mid-2020; the UK Civil Aviation Authority lifted that ban on 16 July 2025, after which PIA launched Islamabad to Manchester flights in October 2025, according to the record of PIA’s UK operations. Routes, days and times will keep changing, so check the airline’s own site the week you fly.

Example A: evening departure from Heathrow in July, landing Islamabad

• Departs Heathrow Tuesday 21:00 BST.
• Assumed flight time: 8 hours. That brings the aircraft down at 05:00 BST on Wednesday.
• Add 4 hours for Pakistan in the UK summer: Wednesday 09:00 PKT.
• What the ticket shows: arrival Wednesday 09:00. What goes on the booking: Wednesday, 09:00 PKT, plus the flight number.

The trap here is modest. The only real risk is booking Tuesday because the traveller “flies on Tuesday”.

Example B: the same flight in January

• Departs Heathrow Tuesday 21:00 GMT.
• Assumed flight time: 8 hours, landing at 05:00 GMT on Wednesday.
• Add 5 hours in the UK winter: Wednesday 10:00 PKT.

Same departure time, one hour later on the ground. Anyone who copied last summer’s booking as a template, or who told a relative “it lands at nine, same as last time”, is now an hour out.

Example C: afternoon departure, after-midnight landing in Lahore

• Departs Heathrow Monday 14:30 GMT.
• Assumed flight time: 8 hours, landing at 22:30 GMT on Monday.
• Add 5 hours: Tuesday 03:30 PKT.

This is the booking that fails most often. In London the arrival still feels like Monday evening. In Lahore it is the small hours of Tuesday. A pickup booked for “Monday 03:30” would be a car at Allama Iqbal International a full 24 hours before the aircraft lands, and hours before it has even left Heathrow. The correct booking is Tuesday, 03:30 PKT. If you are arranging a car to meet a flight at that hour, start from the Lahore airport taxi and transfer page.

Example D: a connection through the Gulf

One-stop itineraries via a Gulf hub add a third clock on the middle legs. Ignore it. Only the final arrival line, in Pakistani time, matters for the pickup. If you are rebooked after a delay, send the new flight number rather than a recalculated time.

Approval windows: your evening is the driver’s night

Many UK to Pakistan journeys are not booked by the passenger. A son in Birmingham books for his parents in Jhelum; an HR team in Manchester approves transport for a visiting engineer. Someone in Britain has to say yes, and someone in Pakistan has to act on it.

The conversion table shows the problem. At 6pm on a winter weekday in London, it is 11pm in Islamabad. The approver has finished work and finally has time to read the quote; the people who would assign a car and brief a driver have finished for the day too. An approval sent at 10pm UK time lands at 3am Pakistan time. If the pickup is at 7am PKT, the operator has at best a few working hours to act on it, and possibly none.

A practical way to set internal deadlines:

1. Work backwards from the pickup in PKT. Write the pickup time down in Pakistan time first, then convert the deadline to UK time, not the other way round.
2. Aim to approve during Pakistan’s working day. In UK winter, 9am to 5pm PKT is 4am to noon GMT. In UK summer it is 5am to 1pm BST. For a UK approver, that means mornings are useful and evenings mostly are not.
3. Treat anything after about 5pm UK time as next-day in Pakistan. It may still be read, but plan as if it will not be acted on until the following Pakistani morning.
4. For early-morning pickups, approve the day before. A 5am PKT airport run on Thursday should be signed off by Wednesday UK morning, not Wednesday night.
5. Name a single decision-maker. Group approvals across two countries are where timing collapses. One person with authority, awake at a sensible hour, beats five people in a chat.

None of this means a late request cannot be handled; it means a late request carries risk that a morning request does not. With iDrive, a request is reviewed and then confirmed; it is not accepted automatically, and availability depends on the vehicle, route and notice given. The earlier in Pakistan’s day the request arrives, the more room there is to confirm it properly.

Office hours and support windows: think in PKT

Any business in Pakistan, from an operator’s booking desk to a hotel front office, publishes its hours in Pakistani time. When you see “open 9am to 9pm”, read it as PKT and convert back to UK time before assuming you can call after work.

For your own booking, check the support hours and contact routes shown on the booking confirmation or the operator’s contact page rather than relying on assumptions, and note them in both clocks. Before you fly, add a second world clock set to Karachi; the time zone database behind most phones names Pakistan’s single zone Asia/Karachi.

The two weekends when Pakistan time vs London time shifts

For most of the year the offset is stable and people get used to it. The errors cluster around the last Sunday of March and the last Sunday of October, when the UK changes clocks and Pakistan does not.

• Recurring calendar entries move. A weekly call with a driver or a family member set at “4pm Pakistan time” in a UK calendar will often be stored in UK time. After the switch it lands an hour early or late in Pakistan.
• Bookings made before the switch for travel after it. If you book in September for a flight in November, do the conversion for November’s offset, not September’s. The same is true in reverse for a March booking and an April flight.
• Flights on the switch-over Sunday itself. A departure in the small hours of that Sunday can involve both offsets in one journey. Take the arrival time from the ticket and do not attempt to recalculate it.

The simplest defence: during those weeks, confirm every time-sensitive arrangement in PKT, in writing, with the day of the week spelled out. “Thursday 29 October, 06:15 PKT” cannot be misread in the way that “Thursday at six” can.

Return journeys: the gap runs the other way

Going home, you are booking a pickup in Pakistan for a flight that will arrive in the UK. The pickup is still in PKT. What changes is the planning: people tend to anchor on the UK arrival time (“we land at Heathrow at 7pm”) and work backwards, adding a conversion error at the very start.

Work from the departure line of the ticket instead, which is printed in Pakistan time, and subtract your time for the drive, check-in and security. The number of hours to leave for that depends on the airport, the time of day and where you are staying; the Islamabad airport transfer page is a good place to start for the capital, whose airport sits roughly 25 km south-west of Islamabad, between the city and Rawalpindi, according to its published location.

Late-night departures raise the same date problem as arrivals. A flight that leaves at 02:00 PKT on Saturday means a pickup on Friday evening. Book the pickup for the date and time you actually need the car, and say explicitly that the flight is the following calendar day.

A booking checklist for UK-based organisers

1. Take the arrival time and date from the airline’s ticket, in local time, with the flight number.
2. Check whether the travel date falls before or after a UK clock change, and use the right offset for any conversion you still need.
3. Write “PKT” beside every time you send to Pakistan, and spell out the day of the week.
4. For arrivals between midnight and 6am PKT, double-check that the booked date is the landing date, not the departure date.
5. Approve or confirm during Pakistan’s working day, which for a UK approver means a UK morning.
6. If the flight changes, send the new flight number. Do not send a recalculated time on its own.

If you are handing the arrangements to a relative, our sister service Pakistan Taxi, which also runs on the iDrive network, has a family-friendly UK departure checklist for an airport pickup in Pakistan that works well alongside this one.

Next step

When the times are straight, put them in writing once. Submit your journey through the iDrive booking request form with the flight number, the arrival date and time in PKT, the passenger count and luggage. For travellers still in the UK, the page on arranging Pakistan transport before you fly sets out the planning side in more detail. Either way, a request is reviewed and confirmed by the team; the confirmation, not the form, is what you should rely on. If your journey touches areas beyond the main cities, read the UK government’s Pakistan travel advice before you finalise plans, as it advises against travel to several parts of the country.

Questions people ask

Is Pakistan 4 or 5 hours ahead of the UK?

Both, depending on the season. Pakistan is 4 hours ahead while the UK is on British Summer Time (last Sunday in March to last Sunday in October) and 5 hours ahead while the UK is on GMT.

Does Pakistan have daylight saving time?

No. Pakistan stays on UTC+5 all year. It tried daylight saving in 2002 and in 2008 to 2009, and has not used it since.

Should I give my pickup time in UK time or Pakistan time?

Pakistan time. The arrival time on your airline ticket is already in Pakistani local time, so copy it directly and label it PKT.

Is there a single London to Islamabad time converter rule I can remember?

Add 4 hours to London time in summer and 5 in winter to get Islamabad time. Islamabad, Lahore and Karachi all share the same time.
