I receieve payments every two weeks.

I have a budget spreadsheet and I want to set up a function which tells me
the number of even-numbered weeks in the current month. I can then multiply
this figure, by the amount of each payment and include it in my budget
calculations.

Also, I want to know how to identify the start and end of month weeknumbers,
for each month. I can then use arguments to update the budget when the
payments are actually received?
