Formula: Unix timestamp = seconds since January 1, 1970 00:00:00 UTC

Unix timestamps are the universal standard for representing time in computing. They represent time as a single number.

Unix timestamp = seconds since January 1, 1970 00:00:00 UTC

Multiply Unix seconds by 1000 to get JavaScript milliseconds. Divide by 1000 for the reverse.

1700000000 = Nov 14, 2023 22:13:20 UTC

1.7 billion seconds since epoch

2024-01-01 00:00:00 = 1704067200

Midnight Jan 1, 2024 UTC as Unix timestamp

Frequently Asked Questions

What is a Unix timestamp?

The number of seconds elapsed since January 1, 1970 00:00:00 UTC (the Unix Epoch).

What is the Y2K38 problem?

On January 19, 2038, 32-bit Unix timestamps will overflow. 64-bit systems handle dates billions of years into the future.

How do I get the current Unix timestamp?

In JavaScript: Math.floor(Date.now()/1000). In Python: import time; int(time.time()).

Seconds vs milliseconds?

Unix timestamps are traditionally in seconds. JavaScript's Date.now() returns milliseconds. This tool auto-detects based on digit count.
