Dgb4thebest, you better fix this one. There are only 52 weeks in my year.
Maybe if yours has 54 that means you get another 2 weeks of school
plus there are 365 days in a year (366 in a leap year)
Plus
weekdays often refers to mon to fri so you could say there are 5 weekdays and 2 weekend days in a week.
But that is rather ambiguous I think.
