In excel I use the formula =networkdays(A1,A2) [where A1 and A2 are dates] to get the number of weekdays between 2 dates. Is there a formula to get the number of Saturdays and number of Sundays?

So basically there are 2 dates, I need the number of Saturdays between these dates, and another formula for number of Sundays.

Would appreciate any help. Thanks.
