What is a time zone converter?
A time zone converter tells you what time it will be in other cities when it is a certain time in yours. It is useful for scheduling meetings, joining online classes, calling family abroad, following sports and live events, and avoiding messages at the wrong hour for a colleague in another country.
Pick the city you are starting from, choose a date and time, and the tool shows the local time and date in twelve popular cities, including Pakistan, the Gulf, the UK, the USA, India and Australia.
How time zones work
The world is divided into time zones measured as an offset from UTC, the global reference time. Pakistan is UTC+5 all year. The UAE is UTC+4, Saudi Arabia is UTC+3 and India is UTC+5:30. The UK is UTC+0 in winter and UTC+1 in summer, while New York is UTC-5 in winter and UTC-4 in summer.
So 3 PM in Karachi is 10 AM in London in winter and 11 AM in London in summer. Because Pakistan does not change its clocks, the gap with cities that use daylight saving time shifts by an hour during the year.
Why dates can differ
Cities far apart can be on different calendar days at the same moment. When it is late evening in New York, it is already the next morning in Karachi or Sydney. Always check the date shown on each card before you confirm a meeting or deadline.
How to use the converter
- Choose the city your time refers to in From city.
- Set the date and time. It starts with the current time.
- Press Convert.
- Read the local day and time for each city in the result cards.
Practical tips
- Pick meeting times that fall in normal working hours for everyone, and write the city name next to the time to avoid confusion.
- Check the conversion again when daylight saving starts or ends in the UK, Europe or the USA, since the gap changes on those dates.
- For international deadlines, ask whether the time is in UTC or in a local time zone.
- Use the date shown on the card, not just the clock, when planning travel or live events.
Frequently asked questions
Does it handle daylight saving time?
Yes. Your browser applies the correct rules for each city on the date you choose.
Why does a city show a different date?
It can be many hours ahead or behind, so the calendar day can differ.
Why is Pakistan not affected by daylight saving?
Pakistan uses a fixed offset of UTC+5, so only the other country changes its clocks.
