end date is 3, then subtract 3 days from the total days, if the end date is 6 or Sunday, subtract 6 or 7, and then add 1 or 2 at the end.
There is no difficulty in the algorithm, the core idea is to adjust this time period to 7 of integers, and then multiplied by 2, in minus or plus more and less than Saturday or Sunday, is the sum of Saturday and Sunday. The final calculation of the number of days, not recommended by date (z) to calculate, because the general will not be good, related to the
