In VBA for excel, how can I find out how many days are in a specific month
for a specific year (these are held in variables)?
For example: I have "curr_month" holding the current month and "curr_year"
holding the current year as well as "last_month", "last_year", etc.
I am trying to get the sum of a category from all the days in a month in a
column, but the months I will want will change and the days in these months
will change with leap years (februrary), etc. Therefore, instead of
hardcoding all the years this will happen, is there a function in VBA that
does this sort of thing? Thanks!
