What is a Unix Timestamp?
A Unix timestamp is a way of tracking time as a running total of seconds. The count starts at the Unix epoch on January 1, 1970, at 00:00:00 UTC. For example, the Unix timestamp 1704067200 corresponds to January 1, 2024, 00:00:00 UTC.
Unix timestamps are used extensively in software development, databases, APIs, and system logs because they provide a timezone-independent, language-agnostic representation of a moment in time. Unlike human-readable date formats that vary by locale (such as MM/DD/YYYY vs DD/MM/YYYY), a Unix timestamp is a single unambiguous integer that any system can interpret consistently.
Timestamps can be expressed in seconds (10 digits) or milliseconds (13 digits). Many modern systems, including JavaScript and Java, use millisecond precision by default. Our converter tools automatically detect the format and handle both seamlessly.
