Unix Timestamp Converter
Convert epoch timestamps to dates and dates to timestampsDatabases, APIs, and log files love storing time as a single number: seconds since January 1, 1970. Humans cannot read those numbers at a glance. Paste a timestamp to see the real date and time, or pick a date to get the timestamp back.

How to use the Unix Timestamp Converter
Read the converted date
Check the UTC, local and relative readings side by side.
Convert a date back
Or pick a date and time to get its timestamp in seconds and milliseconds.

About the Unix Timestamp Converter
Epoch timestamps are everywhere in development: API responses, database rows, JWT expiry claims, log files and cache headers. This free converter handles both directions, auto-detects seconds versus milliseconds, and shows UTC and your local timezone together.
A live ticking clock of the current timestamp helps when seeding test data or checking token expiry. Everything runs locally in your browser, and relative times like 'in 2 days' update with the conversion.
Where it helps most
Reading the numbers systems actually store.
JWT expiry checks
The exp, iat, and nbf claims inside a JWT are Unix timestamps. Converting exp is the fastest way to see when a token dies.
Reading log files
Log entries stamped as integers become readable the moment they are converted. If you debug distributed systems, you read epoch time weekly whether you planned to or not.
Database columns
Database created_at columns stored as integers and API responses with numeric dates all speak this language. Convert them into something a human can read at a glance.
Cache TTL math
Cache TTL calculations and token lifetimes are all timestamp arithmetic. Converting them turns abstract integers into concrete dates you can reason about.
Traps worth knowing
Two classic mistakes, one piece of trivia.
Seconds vs milliseconds
A 10-digit timestamp counts seconds, a 13-digit one counts milliseconds. Mixing them up produces dates in 1970 or the year 50000.
Timestamps are UTC
A timestamp is always UTC underneath. The converter shows UTC and your local time, since local rendering is what users experience.
The Year 2038 problem
Systems storing timestamps in signed 32-bit integers overflow on January 19, 2038, wrapping to 1901. Modern 64-bit systems are unaffected, but old databases still carry the risk.
Unix Timestamp Converter: built for trust
Convert both directions in one box: timestamps to dates, dates to timestamps, shown in UTC and local time.
Unix Timestamp Converter FAQs
Count the digits. A 10-digit timestamp counts seconds since the epoch, the classic Unix convention, while a 13-digit timestamp counts milliseconds, the JavaScript Date convention. Converting a seconds value as milliseconds gives a date in 1970; converting milliseconds as seconds gives a date tens of thousands of years out.
