About timer.ly
A free, account-free countdown service that turns any moment into a shareable URL.
timer.ly was built by Sebastian Messingfeld as a tiny side-project to scratch a simple itch: most countdown sites either require an account, lose your timer the moment you close the tab, or wrap a useful URL in a wall of ads. timer.ly does none of that. The countdown lives in the URL itself. Open the link, see a live timer. Share the link, and the preview unfurls with time remaining in chat apps, email, and calendar invites.
Three primitives cover every case. Duration timers like /in/25m for a Pomodoro or /in/2h30m for an exam. Target-date countdowns like /at/2026-12-25T15:00:00Z or named events like /to/christmas that resolve to the next occurrence. And count-up since past dates like /since/2020-03-11 for tracking elapsed time.
The site speaks five languages — English, German, French, Spanish, Italian — with native URL slugs (/de/bis/weihnachten, /fr/jusqu/noel, /es/hasta/navidad). Holiday calendars cover the UK, US, Germany (with all 16 Bundesländer for Schulferien, sourced from the KMK Ferienkalender), France, Spain, and Italy.
No accounts. No cookies. No advertising. The codebase is hand-written TypeScript on top of Astro, deployed on Vercel. If you find a bug or a wrong holiday date, the contact page below is the fastest way to reach us.
Why timer.ly
Built differently from every other countdown tool.
-
The URL is the timer
No accounts, no databases — the countdown lives in the link itself. Bookmark it, share it, paste it in chat. It just works, forever.
-
No signup, no ads, no cookies
Compare with Google Timer (interstitials), alarm apps (require install), calendar reminders (require a calendar). Open a timer.ly link and you see a clock.
-
Five languages, native URLs
/de/bis/weihnachten, /fr/jusqu/noel, /es/hasta/navidad, /it/fino-a/natale — not just translated copy, properly routed slugs for each locale.
-
Holiday calendars built in
UK + US holidays, German Feiertage + Schulferien (KMK), France, Spain, Italy. No date hunting required.
-
Agent-ready from day one
Public MCP server, OpenAPI 3.1 spec, NLWeb /ask endpoint, schema.org markup, llms-full.txt — designed so AI agents can build countdowns programmatically. Full developer docs.
