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.
