Unix Timestamp Converter
Convert Unix timestamps to dates and dates to timestamps, in both directions.
The Unix Timestamp Converter converts Unix timestamps to human-readable dates and dates back to timestamps in both directions. It is a quick reference for logs, APIs, and debugging.
What is a Unix Timestamp?
A Unix timestamp is a way of representing a point in time as the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC, known as the Unix epoch. This system is widely used in computing because it provides a simple, consistent way to track and compare timestamps across different systems and programming languages, regardless of time zones or daylight saving time changes.
Most programming languages have built-in functions to work with Unix timestamps. For example, in JavaScript you can get the current timestamp using Date.now() / 1000, and in Python you can use time.time(). Web APIs, databases, and logging systems often use Unix timestamps because they're compact and easy to perform calculations with. Understanding timestamps is essential for developers working with time-based data.
This converter helps you translate between human-readable dates and computer-friendly timestamps. It supports both local time and UTC conversions, making it useful when working with distributed systems or when you need to verify that a timestamp corresponds to the expected date. The tool runs entirely in your browser with no data collection, ensuring privacy and speed.
How to use this Unix Timestamp Converter
- Enter a Unix timestamp (seconds since epoch) to convert it to a readable date and time.
- Or select a date and time using the datetime picker to get the corresponding Unix timestamp.
- View both local time and UTC time in the results section.
- Click the result to copy the timestamp to your clipboard.
- The tool automatically updates when you change either the timestamp or date field.
FAQ
What is a Unix timestamp?
A Unix timestamp represents the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds. It's widely used in computing systems for logging and time tracking.
Is it in seconds or milliseconds?
Unix timestamps are typically in seconds. Some systems use milliseconds (like JavaScript Date.now()), but this converter accepts and displays seconds as the standard Unix timestamp format.
Are the timestamps I convert ever uploaded or stored?
No, all timestamp conversions happen entirely in your browser using client-side JavaScript. No timestamp or date data is uploaded or stored.
Is this converter free?
Yes, completely free with no limits. You can convert as many timestamps as you need.
