Why we built this timestamp tool: the one we kept needing.

Every time we needed to turn an epoch value into a date, we ended up doing mental math or digging through docs. So we made a single page that converts instantly with automatic timezone detection.

1. 2025 Shipped
   One converter, built for developers who just need the number Convert Unix timestamps to human-readable dates instantly, with automatic timezone detection and no fuss.
2. Now In progress
   Growing into a full developer time toolkit We've been adding adjacent tools - JWT, UUID, ULID, and Snowflake decoders, a cron builder, week-number and leap-year checkers - because developers who come for the converter usually need one of these next.
3. Next Goal
   Make every tool as fast and self-contained as the first Next we're polishing the newer tools to match the original converter's feel - instant, dependency-free, and no rough edges.

This tool is one of several products built by the same small team, under RapidFoundry. Same rules everywhere: free where we can make it free, and nothing about you sold to anyone.
