Novel calendar system creates regular dates

A US physicist fed up with having to revise his course schedule due dates every year proposes a 364-day year, which means every date falls on the same day of the week every year. A ‘leap-week’ unattached to any month is added every five to six years. Many months would have different lengths than they now do. To answer expected criticism from people whose birthdays are ‘stuck’ on an undesireable day of the week, he gives us all permission to celebrate our birthdays on the weekend before or after their actual date.
