Workflow
Convert a Date to a Timestamp and Back
Working with Unix time means jumping between human dates and epoch seconds. This workflow shows both directions: convert a date to a timestamp for your code, then turn a raw timestamp back into a readable date to verify it.
-
1
Date to timestamp
Enter a date and time in Date to Timestamp to get the matching Unix epoch value you can paste into your code or API.

2
Timestamp back to date
Paste a raw timestamp into the Unix Timestamp Converter to read it back as a human date and confirm the value is what you expected.

When to Use This Workflow
- Debugging timestamps in logs and APIs
- Setting expiry or scheduled times in code
- Verifying a stored epoch value is correct
- Comparing a database date against a raw timestamp
Frequently Asked Questions
A Unix timestamp is the number of seconds since 1 January 1970 (UTC). It is a compact, timezone-free way for systems to store and compare points in time.
You convert a date to a timestamp to store or send it, and a timestamp back to a date to read or verify it. Doing both confirms the value round-trips correctly.
Unix timestamps are based on UTC. When you read a timestamp as a date, mind the timezone you display it in so the result matches what you expect.
Yes. Both tools convert in your browser, so your dates and timestamps are not sent anywhere.
