A Unix timestamp (also known as Unix epoch time) is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds. It is a standard way to represent a point in time across systems.
Unix timestamps are traditionally in seconds (10 digits around 2024). JavaScript and many APIs use milliseconds (13 digits). This tool auto-detects: values above 1e12 are treated as milliseconds.
A Unix timestamp represents an absolute moment in time. The displayed date changes based on timezone offset. Use the timezone selector to view the timestamp in UTC or your local timezone.
