Every 4 years: Add a leap day.
Every 100 years:
Don't add the leap day.
Every 400 years:
Do add the leap day.
Every 4000 years: Don't add the leap day.[snapback]99535[/snapback]

Do you have a source to cite there? No web site I saw when I was Googling the last one (just to be sure...I was fairly certain of the answer off the top of my head) mentioned the 4000 year part.[/quote]
It seems to be one of those cyber legends that spread without substantiation. Best I can tell, the math for a 4000-year-rule makes sense (provided nothing unexpected happens to our orbit for the next two millenia) but it is not an official calendar rule.
Plenty of links contradict each other. Here are two:
