I need some help calculating the networkhours between 2 dates. i dont want
weekends or holidays included. THe hours are from 8am-5pm. i have tried
almost every formula i can find on the internet with no luck. i have dates
starting at random times throughout the week. I am using a NOW() formula in a
cell for the end date. I want to be able to drag down the formula and
calculate the rest of the cells. Please help!
