Calculating a Date Five Days before the First Business Day

DeWayne has a date in cell A1, and it is easy to extract the month from that date. What he needs to do, however, is to calculate the date that is five calendar days before the first business day of the month. Thus, if the date in cell A1 is September 26, 2012, then the first business day of the month would be September 3 and five days before that would be August 29.

There are many different formulas you can use to derive such a date. The shortest one that I've come across is this one:

=WORKDAY(A1-DAY(A1),1)-5

It subtracts the day of the month from the current date, which gives the last day of the previous month. Using this as a parameter for the WORKDAY function, along with a second parameter of 1, gives you the first workday (business day) of the current month. Five days is then subtracted from this date, giving the desired result.

You could also, if you prefer, use the EOMONTH function within the formula, in this manner:

=WORKDAY(EOMONTH(A1,-1),1)-5

The EOMONTH(A1,-1) portion of the formula gives the same result as A1-DAY(A1), which is the last day of the previous month.

You could also use the third parameter of the WORKDAY function to take holidays into account, if you desire. The easiest way to do this is in this manner:

=WORKDAY(A1-DAY(A1),1,MyHolidays)-5

In this usage, MyHolidays is a name you assign to a range of cells, where each cell contains the date of a holiday during the year.

It should be noted that the two functions used so far (WORKDAY and EOMONTH) are both part of the Analysis ToolPak, which must be installed and enabled on your system in order for the functions to work. (How you enable the ToolPak is covered in other issues of ExcelTips.)

If you don't want to use the Analysis ToolPak for some reason, you can use a different formulaic approach, such as the following:

=A1-DAY(A1)+1+(WEEKDAY(A1-DAY(A1))=7)+2*(WEEKDAY(A1-DAY(A1))=6)-5

The formula calculates the first day of the month and then adds appropriate values based on whether the first day of the month is a Saturday or Sunday. Then, five days are subtracted from the result.

I would like to know how to calculate the end date of a course. I know the start date and the number of days in the course. For example

IF start date = 1/2/2014
Number of days = 84

How do I calculate the end date in excel 7 formula?

In addition, students must spend 84 days in the course. However, some students will start later, have the same time off but MUST spend 84 days in the course. What is the formula in Excel 7 given the following:

IF start date = 2/27/2014
IF time off = 3/29/2014 TO 4/4/2014
Number of days = 84 days (plus 6 days for time off)
