About epochkit

epochkit is a free toolkit for developers who work with timestamps every day — Discord, Slack, Cron, Unix, ISO 8601, YouTube, and timezones, all in one place. No account required.

Why epochkit?

Timestamp conversion is one of those things you do dozens of times a week but never have a good tool for. Most existing converters are slow, generic, and don't handle the formats you actually use — Discord's <t:UNIX:F> syntax, Slack's <!date^...> mrkdwn, cron expressions, or multi-timezone comparisons.

epochkit solves that. Every tool is prerendered at build time — no server, no database, no latency. Everything runs in your browser.
