What is Unix Timestamp?
Unix timestamp (also known as Unix time, POSIX time, or Epoch time) is a system for describing a point in time. It represents the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC (the Unix epoch), not counting leap seconds.
Unix timestamps are widely used in computing because they provide a simple, standardized way to represent time that is independent of time zones and human-readable date formats. They are particularly useful for storing and comparing timestamps in databases and programming applications.

Frequently Asked Questions (FAQ)
How to convert Unix timestamp to date?
Simply enter your Unix timestamp in the converter above. Our tool automatically detects whether it's in seconds (10 digits) or milliseconds (13 digits) format and converts it to a human-readable date. You can also select different output formats and timezones for your specific needs.
What is the difference between seconds and milliseconds timestamp?
Unix timestamp in seconds is a 10-digit number counting seconds since January 1, 1970. Milliseconds timestamp is a 13-digit number that includes milliseconds for more precision. Our converter handles both formats automatically.
How to convert date to Unix timestamp?
Use our date to timestamp converter by entering the year, month, day, hour, minute, and second. Select your timezone and click convert to get the Unix timestamp. The result will be in seconds format, which is the standard Unix timestamp format.
What programming languages use Unix timestamp?
Unix timestamps are widely used across virtually all programming languages and platforms:
Why use Unix timestamp instead of regular date format?
Unix timestamps offer several advantages: they're timezone-independent, easy to compare mathematically, take less storage space, are universally understood across different systems and programming languages, and avoid date parsing issues. They're perfect for databases, APIs, and cross-system data exchange.
What is the Year 2038 problem?
The Year 2038 problem affects 32-bit systems that store Unix timestamps as signed integers. The maximum value (2,147,483,647) represents January 19, 2038 03:14:07 UTC. After this date, 32-bit systems will overflow. Modern 64-bit systems can handle timestamps until the year 292 billion!
How accurate are Unix timestamps?
Standard Unix timestamps are accurate to the second. For higher precision, millisecond timestamps (13 digits) provide accuracy to 0.001 seconds. Some systems also use microsecond (16 digits) or nanosecond precision for scientific and high-frequency applications.
