Timezoners vs WorldTimeBuddy (2026): Which One Fits How Your Team Actually Works?
WorldTimeBuddy is a very good time converter. Timezoners is a shared overlap board for a team you meet with every week. An honest comparison of where each one wins. -
WorldTimeBuddy has been the default answer to "what time is it in Singapore?" for over a decade, and it earned that. If you need to convert one time across a few cities right now, it does the job and you already know how to drive it.
We built Timezoners because we kept hitting the same wall with it: the tenth time you rebuild the same five cities to schedule the same weekly call with the same five people, the tool is no longer saving you time. This is a comparison of where each one genuinely wins, written by the people who make one of them, so weight it accordingly.
What WorldTimeBuddy does well
Credit first, because it's real:
- Quick conversions. Type a city, drag across the grid, read the answer. For a one-off "does 4 PM work for Berlin?" it's hard to beat.
- Familiarity. Half the remote workforce has used it. Zero onboarding.
- The slider grid. Selecting a column and seeing every city's time at once is a genuinely good interaction, and plenty of tools have copied it since.
If your time zone problem is occasional and personal, honestly, keep using it. You don't need another account, and you especially don't need a blog post from a competitor telling you your converter is wrong.
Where it stops
The gaps show up when the same group of people meets every week:
- It thinks in cities, not people. You care about whether Priya is free, not what time it is in Bengaluru. Those aren't the same question: Priya starts at 10, blocks Thursday mornings for deep work, and is in Lisbon this month.
- Nothing persists as a team. Your saved cities live in your browser. Your teammate's live in theirs. There's no shared object you can both look at and trust.
- The free tier is tight. Location count is capped (four, historically) and the interface carries ads. Fine for a converter; cramped for a team of nine.
- Sharing means screenshots. A screenshot of the grid is stale the moment DST moves or someone changes their hours, and it can't answer follow-up questions.
None of these are flaws in what WorldTimeBuddy is. They're the outline of a different product.
What Timezoners does instead
Timezoners is a live overlap board for a specific group of humans:
- People first. Add teammates with their location and their actual working hours, including "starts at 10" and no-meeting blocks. The overlap you see is availability, not just daylight.
- One shared link. The board is the source of truth. Pin it in Slack, paste it in the recurring invite. Anyone with the link sees the same live view, no signup required.
- DST-proof by construction. Boards store locations, not offsets. When clocks change anywhere, the overlap recalculates and the pinned link stays correct. Nobody re-derives anything in March.
- Free, without a squeeze. No location cap to work around, no ads to scroll past.
The honest limitation, same one we state everywhere: Timezoners is not a calendar. Invites still live in Google or Outlook. The board's job is the step before the invite: agreeing on a sane window without anyone doing arithmetic in a chat thread.
Side by side
| Timezoners | WorldTimeBuddy | |
|---|---|---|
| One-off time conversion | Works, but it's not the focus | The best thing it does |
| Saved teammates with working hours | Yes | No, cities only |
| Shared live board via link | Yes, no signup to view | No, per-browser settings |
| No-meeting blocks / deep work hours | Yes | No |
| Free tier | Full product | Capped locations, ads |
| Mobile apps | Web, works on mobile | iOS and Android apps |
| Handles DST | Automatic, board stays live | Correct at lookup time, shares go stale |
Which one should you use?
Use WorldTimeBuddy if your time zone work is occasional lookups: a client call here, a flight there, no recurring cast of characters. A converter is the right tool and it's a good converter.
Use Timezoners if you coordinate with the same people every week. The moment there's a "usual group", the converter workflow means rebuilding shared context that should just persist. Set the board up once (a few minutes: add each person, their hours, their blocks), pin the link, and the weekly "what time works?" thread disappears. We wrote about that thread and what it costs teams in the hidden cost of "what time works?".
Running both is also completely reasonable: WTB in a bookmark for quick personal lookups, a Timezoners board pinned in the team channel for the recurring cadence. They're solving different problems; it just took us a while of using one for the other's job to see it.
