How would it be a 13 Month Calendar? Someday one man made this radical question. He wanted to change the gregorian calendar for a 13 Month Calendar of 28 days each month.

The Formula is: 365/13 = 28, and then we add 1 day extra

First day of the month will be always Sunday, last day always Saturday. The extra day is New Year Day. It doesn't belong to any month or week, basicly it will be a magic day, and in a leap year we will have two magic days.

The new calendar is perfectly structured and well tidy, we will always know what week name a date will be.

What do you think about this idea?
