Timezones.in is a free tool for people who work across time zones: a live world map with a day-and-night line, a converter for every pair of timezone abbreviations, city-to-city pages, a meeting planner, and email alerts before clocks change.
It is designed, built and run by Boffin Coders, a studio in Mohali, India that designs, builds and ranks websites and apps for small businesses and for agencies that need a build partner. This site is one of the studio’s own products, and it is maintained the way client work is: server-rendered pages, real data, and a privacy notice written to be read.
What is on the site
- 9,045 abbreviation-to-abbreviation conversion pages, each with live clocks, an hour table and the best time to call
- 999 city pages across 247 countries and 316 zones, plus city-to-city pairs
- Daylight-saving dates for every country, an abbreviation glossary, UTC offset pages, an embeddable clock and a JSON API
- A meeting planner that shows everyone’s working hours side by side and exports to any calendar
How it is built
The site is a Next.js application rendered on the server, so every page is complete HTML before any JavaScript runs. Timezone rules come from the IANA tz database through ICU; the catalogue of zone names and cities comes from the open-source @vvo/tzdb package, and the map from Natural Earth via world-atlas. Accounts, alerts and the API run on a small Node.js service with a MongoDB database, backed up nightly. Both parts are hosted on a single virtual server, and the site is rebuilt monthly so the timezone data stays current.
Privacy, in one paragraph
You can use everything except alerts and the API without an account. Analytics only runs if you allow it in the cookie banner. An account is just an email address; there are no passwords. You can download or delete everything from your account page in one click. The full privacy notice is written in plain English.
Errors and requests
If a time is wrong, tell us — timezone data changes several times a year and we rebuild when it does. Use the contact and data-request form.
