How Many Weeks Are In a Year? - thecalculatorsite.com
A normal year in the 'modern' calendar has 365 days, which, when divided by 7 (Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday) equals 52.1428571 weeks. Every four years, there is a leap year*, adding an extra day into the calendar (pity those 17 year olds born on February 29th 2000, who have only had 4 true birthdays).
