- [Instructor] If you're working…with billing type information,…you may encounter the need to calculate…the previous billing date or billing date…that often occurs perhaps at the end of the previous month.…So I've got some entries over here in column A…on this worksheet called FirstDayLastDay.…We want to calculate in affect here,…the billing date from the previous month.…It's going to be September 30th,…the last day of the previous month,…and there're a couple of couple ways we can do this.…If you look at that date, October 20th,…what happens if we subtract 20 from it?…It takes us back to the last day of the previous month.…
So if we can somehow isolate the day.…So in this particular movie we'll be seeing…a couple of different functions…that you might not have seen;…they're relatively easy to work with.…We'll be using the Day function first of all,…in this formula.…Equal this particular date minus the day of that date,…the day of the month is what that really means,…so we're subtracting 20 here and as I press enter,…
