How to use the time zone converter
Choose the source city, enter the date and time you want (or click "Now" to use the current time), and add the destination cities. The converter automatically calculates the time zone difference, already accounting for daylight saving time when applicable.
When should you use a time zone converter?
A time zone converter is essential in many everyday global situations: scheduling meetings with international teams, arranging video calls with family or friends abroad, following live events such as games, launches and broadcasts in other countries, calculating arrival times for international trips, and coordinating deliveries and deadlines with suppliers or clients on other continents.
Understanding the time difference
The time difference between two cities is calculated based on UTC (Coordinated Universal Time). For example, when it is 9 AM in São Paulo (UTC-3), in Lisbon (UTC+1) it is 1 PM — a difference of 4 hours. In Tokyo (UTC+9) it would be 9 PM the same day — a difference of 12 hours. These differences can change temporarily during daylight saving time, which each country adopts on different dates.
Tips for scheduling international meetings
For meetings with participants across multiple time zones, prefer times between 9 AM and 5 PM in each participant's zone. Use the converter to check whether the chosen time is reasonable for everyone. Remember that some countries do not observe daylight saving time, which can change the usual difference during certain periods of the year.
