What is the maximum number of weekdays in a year? How would you code it?

Question

In order to allocate enough space for an array element for each weekday of a year, I'm trying to work out the maximum number of rows I would need. That lead me onto the question of how I would work it out.

Would you have to calculate the number of days in every year for the next n years and go with that? Or is there (as I suspect) a more elegant solution involving the numbers 365, 366, 2 and 7?

Which libraries would help?

Answer 1

The maximum number of days in a year is 366, this gives us 52 full weeks. In those 52 weeks there are at least 52 * 5 = 260 weekdays.

We are left with 2 days (52 * 7 = 364), it is possible that these 2 days are weekdays.

So maximum number of weekdays in a year is 262.
