Unix Timestamp Converter
Convert Unix epoch timestamps to human dates and dates to seconds or milliseconds.
Convert Unix epoch timestamps into human-readable dates (UTC, GMT, and local time) and convert calendar dates into 10-digit seconds or 13-digit milliseconds timestamps with a live clock ticker.
About Unix Timestamp Converter
Databases, server log files, and APIs communicate timestamps as numeric Unix epochs. Unix Timestamp Converter translates these numbers into clear calendar dates and vice-versa.
How to Use Unix Timestamp Converter
- Check current timestamp: See the live real-time Unix timestamp ticking at the top.
- Convert timestamp to date: Enter any 10-digit or 13-digit number to see the exact calendar time.
- Convert date to timestamp: Pick a date and time to calculate its Unix epoch equivalent.
- Copy converted values: Copy seconds or ISO dates to your clipboard.

Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp (or Epoch time) is the number of seconds that have elapsed since midnight UTC on January 1, 1970, excluding leap seconds.
How do I tell seconds from milliseconds?
Timestamps with 10 digits (e.g. 1740000000) are in seconds. Timestamps with 13 digits (e.g. 1740000000000) are in milliseconds (JavaScript standard).
What is the Year 2038 problem?
On January 19, 2038, 32-bit signed integers will overflow. Modern 64-bit systems represent timestamps well past hundreds of billions of years.
Does this tool support timezone conversions?
Yes, the tool displays the converted date in UTC/GMT as well as your local device timezone and standard ISO 8601 string format.
