Convert a time from one time zone to another — perfect for meetings, calls and travel across countries.
1. Pick the date and time. 2. Choose the “from” and “to” time zones. 3. Click Convert Time.
Note: the entered time is treated as local time on your device; the conversion shows the same moment in the other zone.
A time zone converter changes a time in one part of the world into the time in another part. The world is divided into time zones because the sun rises at different times in different places. When it is 3 in the afternoon in Pakistan, it is still morning in London and early morning in New York. This free time zone converter helps you plan meetings, phone calls, online classes, live streams and travel across countries, so nobody joins an hour early or an hour late.
Remote work, online study and international families have made time zone maths an everyday problem. A team may have members in Pakistan, India, the UK, the UAE and the USA, and finding one hour that suits everyone is hard without a converter. The same problem appears when booking a flight, watching a live match, or calling a relative abroad. Instead of counting hours on your fingers and worrying about daylight saving time, pick the date, the time and the two zones, and this converter gives the answer at once.
Take a meeting at 3:00 PM Pakistan time (PKT, UTC+5) on a winter day. In London (GMT, UTC+0) that is 10:00 AM the same day, because Pakistan is 5 hours ahead of London in winter. In New York (EST, UTC-5) it is 5:00 AM, because Pakistan is 10 hours ahead of New York in winter. In summer the gap is smaller, because London moves to BST (UTC+1) and New York moves to EDT (UTC-4). Another example: a call at 9:00 AM New York time is 7:00 PM the same day in Pakistan.
Each time zone is measured from UTC, the world time standard. Pakistan is UTC+5, India is UTC+5:30, the UAE is UTC+4, Japan is UTC+9, and the UK is UTC+0 in winter and UTC+1 in summer. Some countries move their clocks forward by one hour in summer, which is called daylight saving time, and back again in winter. Pakistan and India do not use daylight saving, but the UK, the USA and Australia do, and their change dates are different. This converter uses your browser's built-in time zone data, so daylight saving is handled for the date you pick.
Always pick the date, not just the time. Daylight saving changes the answer, so the date matters as much as the time. Write both times in the invite. When you invite people to a meeting, write the time in your zone and in theirs, so nobody has to convert it. Check the day too. A late-night call in one country can be early morning the next day in another, so check the date on both sides. Use UTC for records. If you keep notes or logs, write the time in UTC as well, because it never changes with daylight saving. Recheck before travel. Time zone rules sometimes change, so check again close to the date of an important call or flight.
Suppose it is 10 November 2026 at 3:00 PM in Pakistan (PKT, UTC+5). In London the time is 10:00 AM, because London is on GMT (UTC+0) in November and is 5 hours behind Pakistan. In New York it is 5:00 AM, because New York is on Eastern Standard Time (UTC-5) and is 10 hours behind Pakistan. In Dubai it is 2:00 PM, because Dubai is on GST (UTC+4) and is 1 hour behind Pakistan. Enter 10 November 2026, 3:00 PM in the converter above and check each city yourself.
Forgetting daylight saving time. London is 4 hours behind Pakistan in summer but 5 hours behind in winter, because the UK changes its clocks. This converter handles it, but people doing it by hand often forget. Mixing up AM and PM. A 3:00 PM meeting in Pakistan is 5:00 AM in New York, not 5:00 PM. Using the wrong date. A meeting late at night can fall on the next day in another country, so always check the date, not just the time. Assuming the difference never changes. Some countries start and end daylight saving on different dates, so the difference between two cities can change during the year. Scheduling at 3 AM for someone. Check the converted time before you send an invitation, so you do not book a meeting in the middle of someone's night.
Pro Tip: For regular meetings with people abroad, pick a time that is reasonable in both zones, such as late afternoon in Pakistan and morning in the United States.
Note: The time you enter is treated as local time on your device. The converter shows the same moment in the other time zone, using your browser's built-in time zone data.
Does it handle daylight saving? Yes. It uses your browser's built-in time-zone data, including daylight saving time, for the date you pick. A time in July can give a different result from the same time in January.
Which zones are included? Pakistan, India, UAE, UK, US East and West, UTC, Japan and Australia. These cover the zones our readers use most for work, study and family calls.
Why does the converter ask for a date and time? Because the time difference between two places can change during the year when one of them starts or ends daylight saving time. The date tells the converter which rules apply.
What is the time difference between Pakistan and the UK? Pakistan is 5 hours ahead of London in winter (GMT) and 4 hours ahead in summer (BST), because the UK moves its clocks forward in summer and Pakistan does not.
What is the time difference between Pakistan and New York? Pakistan is 10 hours ahead of New York in winter (EST) and 9 hours ahead in summer (EDT), because New York moves its clocks forward in summer.
Does this tool save the times I enter? No. The conversion happens in your browser only. The times you enter are never sent to our servers or stored anywhere.
Why is the converted time sometimes a different day? Because time zones are hours apart, converting a late-evening time in one zone can land on the next day in another zone, and converting an early-morning time can land on the previous day. The converter always shows the full date as well as the time, so check both.
Does this converter work for dates in the past? Yes. You can convert any date and time, past or future, as long as your browser has the time zone data for it.
