Typically, how many leap years are in a century?

The Gre­go­ri­an Calendar omits 3 leap days every 400 years, omitting February 29 in the 3 century years (integer mul­ti­ples of 100) that are not also integer mul­ti­ples of 400. For example, 1600 was a leap year, but 1700, 1800 and 1900 were not. Sim­i­lar­ly, 2000 was a leap year, but 2100, 2200, and 2300 will not be.
