Every remote team eventually loses 30 minutes to a meeting nobody can actually attend. The fix isn't a 50-feature productivity suite — it's one good timezone tool you actually use.

The three things a timezone tool needs to do 1. **Compare multiple cities side by side** with working hours highlighted. 2. **Share a meeting link** that auto-adjusts to each viewer's zone. 3. **Be fast** — under one second from open to answer.

That's it. Anything else is bloat.

The recommendation [Timezone Matcher](https://timezonematcher.com) is built exactly to that spec. Add the cities your team works from, drag the time slider, and share the resulting link. No signup, no calendar permission requests, no upsell to a paid plan.

Alternatives - **World Time Buddy**: the original, still solid but ad-heavy on the free tier. - **Every Time Zone**: clean visualisation, weaker for meeting links. - **Google Calendar's "world clock"**: built in if you already live in Calendar, but only secondary time zones.

For asynchronous teams The bigger unlock for fully-async teams isn't a timezone tool — it's removing meetings entirely. But for the meetings you can't remove, picking the time fairly (rotating who takes the bad slot) matters more than the tool.

For developers If you're building any tool that shows time-of-day across geographies, treat timezone correctness as a first-class concern. Use IANA zone identifiers (`Europe/Madrid`), not UTC offsets, because of DST.
