How Time Zone Conversion Works

Every time zone is an offset from UTC (Coordinated Universal Time). To convert, the time is first turned into UTC, then the target zone's offset is added:

Example: Karachi is UTC+5 and London in winter is UTC+0. When it is 5:00 PM in Karachi, it is 12:00 noon in London. In summer London is UTC+1, so the same Karachi time is 1:00 PM there.

Offsets change when a country starts or ends daylight saving time, so always convert using the exact date.

Frequently Asked Questions

How do I convert time from one time zone to another?

Select the time and date, choose the zone you are converting from, then choose the zone you are converting to. Press Convert and the result shows the local time there. The list below also shows the same moment in 12 major cities.

What is the time difference between New York and London?

London is usually 5 hours ahead of New York. For a short time each year the gap is 4 or 6 hours, because the US and the UK change their clocks on different dates. The converter handles this automatically for the date you pick.

What is daylight saving time (DST)?

Daylight saving time moves clocks forward by one hour in spring and back in autumn in many countries. Not every country uses it, and those that do change on different dates. That is why the gap between two cities can change during the year.

What is UTC and how is it different from GMT?

UTC is the world time standard that all time zones are based on. GMT is the time zone used in the UK in winter and is very close to UTC for everyday use. Zones are written as offsets, such as UTC+5 for Pakistan.

How do I find the best time for a meeting across time zones?

Convert your proposed time into every participant's zone and look for hours that fall in normal working times for everyone. The World Clocks panel makes it easy to compare cities at a glance.

What time zone is Pakistan in?

Pakistan uses Pakistan Standard Time (PKT), which is UTC+5 all year. Pakistan has used daylight saving time only in a few past years, and none is currently applied.
