Convert Unix timestamps to human-readable dates and vice versa. Supports both seconds and milliseconds.
Unix Timestamp (also called Epoch Time or POSIX Time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC. It's a standard way to represent time across different systems and programming languages.
Unix timestamps are widely used in databases, APIs, logging systems, and scheduling applications. They're timezone-independent, making them ideal for storing and comparing times across different locations.
Most Unix timestamps use seconds (e.g., 1704067200), but JavaScript and some modern systems use milliseconds (e.g., 1704067200000). This tool supports both formats—toggle the checkbox to switch between them.
