How to use this tool
A quick workflow so you can get the result you need without guesswork.
- 1
Enter a Unix timestamp in seconds or milliseconds to convert it to a readable date.
- 2
Use the date and time fields below to convert a calendar value back into a Unix timestamp.
- 3
Copy the output you need in local time, UTC, seconds, or milliseconds.
Useful examples
Practical cases where this utility saves time and reduces mistakes.
Generate timestamps for testing
Convert known date-time values into seconds or milliseconds when building fixtures or scheduled jobs.
Cross-check time zones
Inspect the same timestamp in both local time and UTC when debugging scheduling issues.
Frequently asked questions
Short answers to the most common questions about the calculator above.
What is a Unix timestamp?
A Unix timestamp counts the number of seconds or milliseconds elapsed since January 1, 1970 at 00:00:00 UTC.
How do I know whether the timestamp is in seconds or milliseconds?
A 10-digit value is usually seconds, while a 13-digit value is usually milliseconds. This converter can interpret either.
Does the timestamp converter show UTC?
Yes. It shows both a local date-time string and the corresponding UTC representation.
Can I convert a future date into a timestamp?
Yes. Enter any valid date and time and the tool will compute the corresponding Unix timestamp.
Convert Unix Timestamps and Calendar Dates Instantly
This timestamp converter turns Unix epoch values into readable dates and converts normal calendar input back into timestamps. It supports both seconds and milliseconds, which makes it useful for API debugging, logging, scheduling, and test data creation.
The tool shows local time and UTC side by side so you can spot timezone mistakes quickly. That is especially helpful when you are checking logs from distributed systems or validating timestamps stored in a database.
Useful for APIs, Databases, and Scheduled Jobs
Unix timestamps appear everywhere: JSON payloads, event records, cron-like systems, analytics data, and queue processors. A fast online epoch converter saves time whenever you need to translate one of those raw values into something human-readable.
By supporting both directions on the same page, this tool also makes it easy to generate a timestamp for a known date during testing or integration work.
