About TimeKit
TimeKit is a free, privacy-first collection of time tools that run entirely in your browser. No servers, no tracking, no registration required — just open a page and start working with time.
Why We Built TimeKit
Time sounds simple until you actually have to work with it. A remote team scattered across Berlin, Bangalore, and San Francisco keeps showing up to meetings at the wrong hour because someone misread a timezone offset. A freelancer juggling several clients needs to add up the hours and minutes spent on each project without firing up a spreadsheet. A student preparing for exams wants a Pomodoro timer — 25 minutes of focused work followed by a 5-minute break — without being ambushed by pop-ups or forced to create an account.
Then there are the one-off questions: how many days until my vacation? What's my exact age in years, months, and days? What does a Unix timestamp of 1700000000 actually mean in human time? Every time we searched for these answers, we landed on cluttered pages full of ads, sign-up walls, and tools that quietly sent our input off to a server. TimeKit is the version we wished existed — clean, fast, and respectful of your attention.
What Makes TimeKit Different
- Runs entirely in your browser. Every timer, conversion, and calculation happens locally in JavaScript. There is no backend that ever sees your input.
- No login, no limits, no watermark. Open a tool, use it, close the tab. We never ask for an email or lock features behind a paywall.
- Bilingual by default. Every tool ships in both English and 简体中文 with hand-written copy, not machine translation.
- Immersive backgrounds and ambient sounds. A Pomodoro session feels different when it's paired with rain, café noise, or a quiet starfield. Focus tools should help you focus, not just count down numbers.
- Shareable results. Countdown URLs and timezone-converter links are bookmarkable, so you can send one link and everyone sees the same moment.

Privacy by Design
Privacy isn't a toggle we added later — it's the starting point. TimeKit has no backend database, no analytics on your input, and no account system. Your timers, alarms, dates, and timestamps never leave your device. The site loads once from Cloudflare's CDN; after that, most tools keep working even if your connection drops.
Built With
TimeKit is built with Astro for fast, content-first pages, Vue 3 for interactive widgets like the timer and Pomodoro, and Tailwind CSS for the visual layer. The whole site is deployed on Cloudflare Pages, so it ships from an edge node close to wherever you are.
