UNIX Holidays

The more I thought about it, the more New Years seems arbitrary. I mean any day during the year could be the start of the year. Now New Years has some significance. People could figure out when the Solstice was, but not until after it was over, so the celebration had to wait.

Now, as computer people we should celebrate dates that are relevant. So I made a program that would calculate dates that have a binary representation that end in 24 zeros. Why 24? To space them evenly about once a year.

#!/usr/bin/perl
use POSIX;
$ENV{'TZ'} = "GMT";

for ($clock = 0; $clock <= 64; $clock++)
	print ctime($clock << 25);

So the holidays are:
