The 1st and 2nd months of a quarter are 4 weeks and the 3rd month of the quarter is 5 weeks. This makes for nice this year/last year comparisons, allows months to always start and end on a week boundary and is generally nice and tidy. But every 4-5 years you have to throw in a 53rd week to keep the 4-4-5 calendar roughly in sync with the normal calendar. So yes, there really is no 53rd week in the normal calendar, but yes there is a "leap" 53rd week in the 4-4-5 calendar.
