Convert between Unix timestamps and human-readable dates
Unix epoch time (also known as Unix timestamp or POSIX time) is a system for describing points in time. It's the number of seconds that have elapsed since 00:00:00 Thursday, 1 January 1970, Coordinated Universal Time (UTC), minus leap seconds. This system is widely used in computer systems and programming languages to represent dates and times.
Our Unix Epoch Converter allows you to convert between human-readable dates and Unix timestamps. You can convert timestamps to dates, get the current timestamp, and choose between seconds and milliseconds precision. We support multiple output formats including local time, UTC, and ISO 8601.
The Unix epoch is 00:00:00 UTC on 1 January 1970. All Unix timestamps count the number of seconds (or milliseconds) since this moment.
Standard Unix timestamps use seconds (10 digits). Milliseconds timestamps use 13 digits and provide millisecond precision (divide by 1000 to get seconds).
The 32-bit signed integer Unix time will overflow on 19 January 2038 (03:14:07 UTC). Modern systems use 64-bit integers which won't overflow for billions of years.
