What people use it for
International meetings
Before sending a calendar invite, check that 3 PM your time isn't 2 AM for the other person. The world clock shows all your tracked zones side by side.
Remote team coordination
Distributed teams use it to know when teammates in other cities are actually at their desks, before pinging them at midnight.
Travel planning
Check the local time at your destination before booking flights or making calls to hotels and tour operators.
Trading and finance
NYSE opens at 9:30 AM ET, London at 8 AM GMT, Tokyo at 9 AM JST. Track all three without doing the math every morning.
Staying in touch with family
Know what time it is for family members living abroad before calling, especially useful across large time differences like US to India or UK to Australia.
Online events
Convert a webinar or live stream start time to your local timezone so you don't show up an hour late.
Where the times come from
Each city's time is calculated by your browser using the IANA time zone database built into it, the same data your phone uses. Daylight saving changes are handled automatically, provided your browser is up to date. Rules do change: Mexico dropped daylight saving in most of the country in 2022, and only updated browsers know that.
Not every offset is a whole hour. India is UTC+5:30, Nepal UTC+5:45 and Australia's Lord Howe Island shifts by just 30 minutes for daylight saving. Mental maths goes wrong on exactly these zones.
The cities you add are saved in local storage on this device. The clocks are only as accurate as your own device's clock, which on most phones and computers is synced to network time within a fraction of a second.
