PlanetClocksWorld Clock
See the current time in several cities side by side. Add the places you work with, and the list is remembered on this device.
How to use the world clock
Choose a city or time zone from the list and press Add. Each card shows the live local time, the date and how many hours that place is ahead of or behind you. Remove a card with the × button, or press Reset to return to the default selection. Your list is saved in your browser's local storage, so it is private and stays on this device.
Tips for working across time zones
When scheduling with people in other countries, look at the date as well as the time: when it is evening in the Americas it is already the next morning in East Asia and Australia. Also keep in mind that the northern and southern hemispheres switch daylight saving time in opposite seasons, so the difference between, for example, London and Sydney changes from 9 to 11 hours during the year.
Use the 12h / 24h button to switch the clock format. For planning a specific meeting time, the time zone converter is more convenient.
