Umm, no.  The Julian calendar counted every fourth year as a leap year.  
The problem was that this added just about 3 extra days every 4 centuries.
That's why the Gregorian calendar adjusted that by designating that every 
year divisible by 100 is *not* a leap year unless divisible by 400.

This is according to the following sources:  
    The World Almanac and Book of Facts (1991)
    The Information Please Almanac (1997)
    Reader's Digest Illustrated Encyclopedic Dictionary (1987)
    Compton's New Century Encyclopedia and Reference Collection II (1995)
    The Software Toolworks Multimedia Encyclopedia (1992)
    The Concise Columbia Encyclopedia (1991, MS Bookshelf edition)
    The World Almanac and Book of Facts (1994, MS Bookshelf edition)
    The New American Desk Encyclopedia (1989)
