Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.8
GPA, above 78 of the 114 other calendar and scheduling apps we grade
Timezone.io is a reference site for the current local time, UTC offsets and daylight saving dates of every time zone, country and major city, with a converter for comparing two places. It also offers shared team boards that group teammates by local time, and a JSON API serving the same data to developers.
To get you started, here are 9 things to know about Timezone.io, taken from its own pages and our grades.
No store rating on record; it's a website you open and read with nothing to set up.
- 1
Best for time zone reference, converter and API
But it isn't a calendar, it has no events or booking, and the pricing page says the monthly API quotas aren't enforced yet.
- 2
Paid plans start at $20 a month
As its pricing page puts it: $20 per month.
- 3
There is a free plan
The reference site, converter and team boards are free to use. The API's Free plan gives 100,000 requests a month at 5 requests a second, with every endpoint and commercial use, and needs no card.
- 4
It runs on Web
Web.
- 5
World clock by zone, country and city
Pages for every time zone, country and major city show the current local time, UTC offset and daylight saving dates, computed from the IANA time zone database.
- 6
Time zone converter
Compare the time in two places, with the offset between them spelled out.
- 7
Team boards
A team shares one public link, and teammates add themselves without an account. The board groups everyone by local time and has a slider to see who is awake at a later hour.
- 8
A 2.8 GPA, above 78 of 114
That is against the other calendar and scheduling apps we grade, on value, the free plan, features, ease of use and platforms.
- 9
You could make this
A calendar at its plainest is events on a grid.

The report card
Best for time zone reference, converter and API
Timezone.io shows local times, UTC offsets and daylight saving dates for every zone, with a converter and a free API of 100,000 requests a month. But it isn't a calendar, it has no events or booking, and the pricing page says the monthly API quotas aren't enforced yet.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | A | The reference site, converter and team boards are free, and the API's free plan allows 100,000 requests a month with commercial use. |
| Free plan and trial | A | Free outright for the site, and the API's free plan needs no card. |
| Features | D | One narrow job: time zone data, a converter and team boards, with no events, invitations or booking. |
| Ease of use | B | No store rating on record; it's a website you open and read with nothing to set up. |
| Platforms and integrations | C | Web only, with a JSON API for developers. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Timezone.io is for
- Fits if you need to check the time in another city or compare two places
- Works for developers who want a free time zone API
Who it is not for
- Not for you if you want a calendar or scheduling app: it has no events or booking pages
- Skip it if you need a phone or desktop app, as it runs in the browser only
- Watch out: monthly API quotas are not enforced yet, and accounts will be emailed first
- Watch out: paid API plans are billed monthly and are non-refundable except where the law requires
Good to know
Good for
- Distributed teams that want one page showing everyone's local time
- Developers who need time zone lookups and conversions from an API

Part 03 · Features
What it does
Its main features, where it runs, what it works with and who makes it
1
Place it runs: Web
World clock, time zone converter, team boards and a time API. Here is what it does, as its own site describes it, and what it covers: public API, calendar.
One narrow job: time zone data, a converter and team boards, with no events, invitations or booking.
- World clock by zone, country and city
- Pages for every time zone, country and major city show the current local time, UTC offset and daylight saving dates, computed from the IANA time zone database.
- Time zone converter
- Compare the time in two places, with the offset between them spelled out.
- Team boards
- A team shares one public link, and teammates add themselves without an account. The board groups everyone by local time and has a slider to see who is awake at a later hour.
- Time zone API
- Endpoints look up the zone at a latitude and longitude, convert a time to up to ten zones with daylight saving gaps flagged, and list the candidates behind an abbreviation such as CST.
- Clear plan limits
- Every API plan has every endpoint, so plans differ only by request volume, per-second rate, support and SLA.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
You could make this
A calendar at its plainest is events on a grid.
What Timezone.io does at its core is calendar, and that is the kind of thing an AI app builder makes well. You would give up one thing, listed below, and little else. It costs $240 a year. An AI app builder starts at about $20 a month on our listings, and you only need it while you build.
What you could make
- Calendar: an app builder makes this well.
- It runs in a browser, which is where something home-made would run too.
What you could not
- An API that other software can build on.
What this rests on. Timezone.io’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
