About Time Zone Link

Time Zone Link is a free, privacy-first toolkit built for anyone who works across time zones — remote teams, frequent travelers, journalists, traders and global students.

What you get

  • Time Zone Converter — convert any time between cities and IANA zones with a shareable URL for meeting invites.
  • World Clock — live local time and UTC offsets for 100+ cities worldwide, refreshed every second.
  • Countdown Timer — precise hours/minutes/seconds with an audio alert at zero.
  • Stopwatch — hundredth-of-a-second precision and unlimited laps.
  • Alarms — unlimited browser alarms with optional system notifications.
  • Blog — practical writing on scheduling, async work and DST for distributed teams.

Privacy by design

Everything runs in your browser. There are no accounts, no third-party trackers, and no advertising. Your alarms are saved in localStorage — never transmitted to a server.

How it works

Time Zone Link uses the browser's Intl API and the IANA time zone database to render accurate local times. Daylight saving transitions are handled automatically.
