```I'm guessing that "weekdays" means for you Monday-Friday. Given daily dates, say in a variable -date-, -dow(date)- is 0 ... 6 on Sunday ... Saturday.

Thus the examples

. count if !inlist(dow(date), 0, 6)

. count if inrange(dow(date), 1, 5)

. egen whatever = total(inrange(dow(date)), by(somethingelse)

show various techniques that may be useful. If this doesn't help, you may need to be more precise about your set-up.

I'm trying to determine the number of week-days between two dates.  Is there an
easy way to do this in Stata?
