What is Timestamp ⇄ Date Converter?
A Unix timestamp is the number of seconds that have elapsed since 1 January 1970 (the "epoch"), and it is how most computer systems store dates internally. A timestamp to date converter translates these raw numbers into readable dates and times, and converts human dates back into timestamps.
The tool shows results in local time, UTC and ISO 8601 format, so you can match whatever your application, log file or database expects.
How to Use the Timestamp ⇄ Date Converter
- Paste a Unix timestamp and click Timestamp → Date.
- Or pick a date and time and click Date → Timestamp.
- Use the current-time button to grab the timestamp for now.
- Read the local, UTC and ISO results in the output panel.

Benefits & Use Cases
Developers debug logs, APIs and databases where dates are stored as epoch numbers. Converting them into readable form — and back again — is a daily task when building and troubleshooting software.
Because everything runs locally, you can convert timestamps instantly without exposing potentially sensitive log data.
The Timestamp ⇄ Date Converter is completely free, needs no sign-up or installation, and runs entirely in your browser — nothing you enter is uploaded to a server, so your data stays private. It works on desktop, tablet and mobile, in light or dark mode.
Tips & Best Practices
Watch the digit count: a 10-digit value is seconds and a 13-digit value is milliseconds — the tool detects and handles both. Servers usually log in UTC while users see local time, so having local, UTC and ISO 8601 side by side makes it easy to line up an event across time zones.
This is a daily companion when debugging APIs, logs and databases. Reformat the surrounding payload with the JSON Formatter, or measure the gap between two calendar dates with the Date Difference Calculator.
FAQ about Timestamp ⇄ Date Converter
What is a Unix timestamp?
It is the count of seconds since midnight UTC on 1 January 1970. It gives every moment a single, timezone-independent number.
Does it accept milliseconds?
Yes. If your timestamp has 13 digits it is treated as milliseconds; 10-digit values are treated as seconds automatically.
Why show UTC and local time?
Servers usually work in UTC while users see local time. Showing both helps you line up logs and user-facing timestamps correctly.
Is the conversion done online?
No. It runs in your browser using your device's clock and timezone, so nothing is sent to a server.
