Epoch Clock (Live Unix Time)

The Epoch Clock displays the live Unix timestamp updating every second — that's the total seconds elapsed since January 1, 1970 (UTC). Enter any Unix timestamp to convert it to a human-readable date, or enter a date and time (year, month, day, hour, minute, second) to get its Unix timestamp. Outputs include the UTC date, ISO 8601, RFC 2822 formats, and the equivalent in your local time zone.

Enter a Unix timestamp in seconds to convert it to a date. Leave blank to use the current time.

Frequently Asked Questions

What is a Unix timestamp (epoch time)?

A Unix timestamp is the total number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC — known as the Unix Epoch. It's a universal, timezone-independent way for computers to track time. For example, the timestamp 1000000000 represents September 9, 2001 at 01:46:40 UTC.

Why does Unix time start on January 1, 1970?

January 1, 1970 was chosen as the reference point (epoch) by the early Unix developers at Bell Labs. It was a convenient, round date close to when the Unix operating system was being developed, making it practical for the systems of that era.

What happens on January 19, 2038?

On January 19, 2038 at 03:14:07 UTC, 32-bit systems that store Unix time as a signed integer will overflow — rolling back to a large negative number representing December 13, 1901. This is known as the Year 2038 Problem (Y2K38). Most modern systems use 64-bit integers, which pushes the overflow date billions of years into the future.

How do I convert a Unix timestamp to a human-readable date?

Enter the Unix timestamp (in seconds) into the 'Unix Timestamp' field above and the tool will instantly display the equivalent UTC date, ISO 8601, RFC 2822 format, and your local time zone equivalent.

How do I convert a date to a Unix timestamp?

Fill in the Year, Month, Day, Hour, Minute, and Second fields in the 'Convert Date → Timestamp' section. The tool will calculate the corresponding Unix epoch timestamp in seconds.

Is Unix time the same everywhere in the world?

Yes — the Unix timestamp itself does not change based on your location. It is always measured in seconds from the UTC epoch. Time zone differences only affect how that timestamp is displayed as a local date and time.

What is the difference between seconds, milliseconds, and microseconds in Unix time?

Standard Unix timestamps count whole seconds since the epoch. Millisecond timestamps (used in JavaScript's Date.now()) multiply this by 1,000. Microsecond timestamps multiply by 1,000,000, and nanosecond timestamps by 1,000,000,000. This tool works with seconds as the base unit.

Can Unix timestamps be negative?

Yes. A negative Unix timestamp represents a date and time before January 1, 1970 UTC. For example, -86400 represents December 31, 1969. Most modern systems and databases support negative timestamps to represent historical dates.
