The only requirement for the add_month function I have is that after d2 = add_month(add_month(d1, N), -N), d1 and d2 should be in the same month. Someone developing a million line program should understand that add_month(add_month(d, 1), 1) may be not the same day as add_month(d, 2). JG> This email thread seems to be writing the repsonse to the FAQ: JG> Q: Why is there no add_month function in the library? JG> A: Because we can't agree on what it means... Does that mean that add_month won't be implemented? What if we call it inc_month, instead of add_month? inc_month (Increase Month) in no way assumes that the day of the month will stay the same, it will just increase the month.
