First and Last Weekday Dates for Each Week of Month

Hi,

I need a formula in cells B1 to B5 to give the dates of the first workday, and a formula in cells D1 to D5 to give the dates of the last workday of each week of the month that is entered in A1 -- appearing in the format:

(A1)April (B1)__________ (C1)to (D1)__________

Thanks,
Gos-C
