About Timestamp Converter
A Unix timestamp (also known as Epoch time or POSIX time) is a system for tracking time as a running total of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC. It is widely used in programming, databases, APIs, and server logs because it provides a timezone-independent, compact way to represent a specific moment in time.
Our Timestamp Converter makes it effortless to translate between Unix timestamps and human-readable dates. Whether you are debugging API responses, analyzing log files, or setting expiration times for tokens and caches, this tool gives you instant conversions in multiple formats including UTC, ISO 8601, and RFC 2822, along with useful metadata like relative time, day of week, and week number.
