In the UNIX Operating System (and all its derivatives), date and time values are stored as the number of seconds since the 1st of January 1970, 00:00:00 UTC.
If you express that number in hexadecimal notation, once every half-a-year-and-a-bitâ„¢ (16,777,216 seconds) the number will end in six zeros. These occasions I like to celebrate.
The next UNIX New Year will occur on 16 Apr 2025, 19:07:44 UTC.
