Timestamp Converter

The Timestamp Converter turns Unix timestamps into human-readable dates and converts dates back into timestamps, across common formats and time zones. A Unix timestamp counts the seconds elapsed since 1 January 1970 UTC, and this tool makes that otherwise opaque number legible at a glance in both directions.

Developers reach for it constantly when reading log files, debugging database fields that store epoch times, and working with APIs that exchange dates as raw numbers. Being able to convert either way removes the friction of mentally decoding a timestamp or hand-building one, which is exactly where small errors tend to creep in.

Conversions are computed in your browser with nothing uploaded, so they are instant and completely private. There is no install and no account, which makes it easy to keep the converter open in a tab as a quick reference throughout a debugging session. Since the conversion never leaves your browser, timestamps drawn from production logs remain entirely private.
