Hey! Reuse That Calendar!

And now, as the time approaches 22:50, an instructive programme on efficient timekeeping: How To Reuse Your Gregorian Calendars:

Our team of crack mathematicians recently designed a complex computer program that assisted us in the creation of the following fourteen lists. These lists should be of much use to environmentally paranoid people, such as us, who wish to save paper and money by reusing their calendars. Every year from 1901 to 2099 AD is listed below. All the years in each group have the same number of days and start on the same day of the week. Calendars that don’t include weird details such as Moon phases should be usable in any year within their group. In order to keep these lists error-free, we request that you kindly inform us of any errors that you may find.
