What is the time difference between two cities?
Planning an international call or getting ready for a trip and need to know the time at your destination? With our time zone calculator, you can instantly compare the current time between two cities anywhere in the world. Simply enter the two cities and the tool shows you the time difference between them as well as the current time in each one.
You can also change the cities or try new ones to compare the time difference across multiple destinations. The time zone calculator is often used to schedule international meetings, plan calls with loved ones abroad, or anticipate jet lag before a trip.
How does the time difference work?
The time difference is the gap in time between two time zones. The Earth is divided into 24 main time zones, each corresponding to a one-hour offset from the Greenwich meridian. For example, when it's noon in Paris, it's six in the morning in New York because there is a six-hour difference between the two cities.
Our tool takes into account the time zones in effect for each city, including any daylight saving time changes if applicable. The displayed difference therefore always remains accurate, even during the transition to summer time or winter time.
When do you need to know the time difference?
Knowing the time difference between two cities is useful in many situations. Professionals working with international teams use it to set meeting times that work for everyone. Travelers rely on it to know their arrival time and better organize themselves on-site. It's also very handy for calling someone abroad without risking waking them up in the middle of the night.
You can also use it to follow a live event taking place in another country, to find out the opening hours of a service in a different time zone, or to anticipate the effects of jet lag based on the number of hours' difference.
