🕐Timestamp

A Unix timestamp represents the number of seconds elapsed since January 1, 1970, 00:00:00 UTC (the epoch). Because it's timezone-independent, it's the standard representation for server communication, database storage, and API responses. However, raw numbers aren't intuitive for humans, which is why a conversion tool is needed. This tool supports bidirectional conversion between Unix timestamps and human-readable date/time formats.

How to Use

1
Choose Conversion Direction
Convert from timestamp to date, or from date to timestamp. The current time display at the top provides a reference point.
2
Enter a Value
Type a number in the timestamp field, or select a date/time using the date picker. Choose seconds or milliseconds, or let auto-detection figure it out.
3
View Results
See the conversion in multiple formats: ISO 8601, local time, UTC, and relative time (e.g., '3 days ago').
4
Copy & Use
Copy the result in your preferred format using the copy button for use in code or documentation.

Tips

💡Click 'Current' to instantly get the timestamp for the current moment.
💡JavaScript's Date.now() returns milliseconds, while Python's time.time() returns seconds. The auto-detect feature handles both automatically.
💡Helpful for API debugging — quickly convert timestamps in responses to readable dates.
💡The relative time display lets you intuitively see how far a timestamp is from the present.

FAQ

Q. What is a Unix timestamp?: A. A Unix timestamp is the number of seconds (or milliseconds) elapsed since January 1, 1970, 00:00:00 UTC (the Unix Epoch). It provides a timezone-independent way to represent a moment in time.
Q. How do I tell if a timestamp is in seconds or milliseconds?: A. A 10-digit number is typically seconds; a 13-digit number is milliseconds. The current time in seconds is around 1,700,000,000 and in milliseconds around 1,700,000,000,000.
Q. Does the result change depending on the timezone?: A. The Unix timestamp itself is always UTC-based and timezone-independent. The tool converts it to a human-readable time in your selected timezone for display purposes only.
Q. What is the Year 2038 Problem (Y2K38)?: A. Systems that store Unix timestamps as a 32-bit signed integer will overflow on January 19, 2038. Modern 64-bit systems are not affected, but embedded systems and legacy databases may still be at risk.
