If you happen to deal with a website template having the copyright year (the four digits at the bottom of virtually every www page on earth) hardcoded as a number in its PHP files, replace it with the following string:
<?=date("Y")?>
and you’ll be surprising your visitors with great immediacy every year in its very first minutes!
(requires “short tags” enabled in PHP configuration)

That’s a great idea. I never thought of that for some reason, but I will be adding that to my copyright. Thanks.
