About
A small toolkit for a problem that shows up in almost every piece of software: representing time correctly.
EpochKit started from a familiar frustration: most timestamp and timezone tools online are either cluttered with intrusive ads, gate basic features like saving a city list behind a signup, or look like they haven't been redesigned since 2010. None of that is necessary for what these tools actually do. A timestamp conversion, a date calculation, a timezone comparison — these are all things a browser can compute instantly, without an account, without a server round-trip, and without your data going anywhere.
It's a collection of small, focused tools and reference guides, all built to run entirely client-side — meaning the JavaScript in your browser does the work, and nothing you type is ever uploaded or stored on a server. That's a genuine design choice, not just a privacy slogan: it's also why every tool here loads and responds instantly, with no backend to wait on.
EpochKit is free to use and supported by advertising, shown via Google AdSense. There's no premium tier, no paywalled features, and no account system — the ads are what keep the tools free and the lights on. See the Privacy Policy for exactly what that involves.
EpochKit is an independent project, built and maintained by someone who kept running into the same small, annoying time-handling problems across different projects and got tired of re-solving them or hunting for a decent tool each time. If you spot something wrong — a calculation that looks off, a broken link, a tool you wish existed — the contact page is the fastest way to reach out.
More tools and guides are added over time, generally driven by the same principle the site started with: solve a real, specific problem well, keep it fast, and don't ask for anything the tool doesn't actually need. See the full tools directory or the blog for everything currently live.
