About this tool
Unix timestamp ↔ human-readable date conversion.
A Unix timestamp is the number of seconds (or milliseconds) since 1 January 1970 00:00:00 UTC. The Timestamp Converter translates a Unix timestamp to a human-readable date/time or converts a date/time back to its Unix timestamp. Supports both seconds and milliseconds. Displays the result in local time, UTC and configurable timezones.
Example
Unix timestamp 1705320000 → 2024-01-15 12:00:00 UTC
Date 2024-01-15 12:00:00 UTC → 1705320000
How to use
- Paste a Unix timestamp (seconds or milliseconds).
- Or enter a date and time in the date field.
- Conversion happens automatically.
- Copy the result in any format.
Features
- Seconds and milliseconds Unix timestamps
- Timestamp → human date
- Human date → timestamp
- UTC and local time display
- Now button for current timestamp
When to use this
Developers reading log files that record events as Unix timestamps — converting to human-readable dates to understand when something happened.
Debugging API responses that return timestamps in epoch format — verifying that a returned date matches expectations.
Database engineers converting stored integer timestamps for display in reports or admin panels.
DevOps engineers checking whether a scheduled job ran at the correct time by comparing the logged timestamp with the expected schedule.
Frequently Asked Questions
What is a Unix timestamp?+
The number of seconds elapsed since 00:00:00 UTC on 1 January 1970. A universal, timezone-independent way to represent a moment in time.
How do I convert a millisecond timestamp?+
Enable the milliseconds toggle. A 13-digit timestamp is typically in milliseconds; a 10-digit one is in seconds.
Why does my timestamp show the wrong date?+
Check whether the timestamp is in seconds (10 digits) or milliseconds (13 digits). Dividing by 1000 converts ms to seconds.
What is the maximum Unix timestamp?+
32-bit systems overflow at 2,147,483,647 (January 19 2038 — the Y2K38 problem). 64-bit systems can handle dates millions of years in the future.
What exactly is a Unix timestamp?+
The number of seconds elapsed since the Unix epoch: midnight on 1 January 1970 UTC. It is the standard time representation in databases, APIs, server logs, and most programming languages.
What happens in 2038?+
32-bit signed integers overflow at 2,147,483,647 seconds (03:14:07 UTC on 19 January 2038). Systems storing timestamps as 32-bit integers will wrap to a negative value. Modern systems use 64-bit integers, which are safe for 292 billion years.
How do I get the current Unix timestamp?+
The tool shows the current timestamp in real time. In code: JavaScript: Date.now()/1000|0 · Python: import time; time.time() · PHP: time() · Unix shell: date +%s.
