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.
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 Timezone.io 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

Keep Timezone.io, or make your own?
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.
What is Timezone.io?
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.
Worth knowing
- It is not a calendar or scheduling app: it has no events, invitations or booking pages, and it runs in the browser only.
- The pricing page says monthly API quotas are not enforced yet, and that accounts will be emailed before they are.
- Paid API plans are billed monthly through Stripe and are non-refundable except where the law requires otherwise.
- Descriptions on zone, country and city pages are AI-assisted drafts that the site says are fact-checked and reviewed by a person.
Key features
- 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.
