# Calculating a Date Five Days before the First Business Day

This tip applies to Excel 2007, 2010, 2013, 2016, 2019, Excel in Microsoft 365, and 2021

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 October 10, 2022, then the first business day of the month would be October 3 and five days before that would be September 28. (It is important to note that the five-day adjustment is based on calendar days, not on business days.)

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 WORKDAY function assumes that the non-workdays are Saturday and Sunday. This might not always be the case, however. If you want the ability to specify different non-workdays, then you should investigate the WORKDAY.INTL function, which was introduced in Excel 2010. It works much the same as the WORKDAY function, except it adds a new parameter that is specified in the third position. For instance, let's say that DeWayne runs a barber shop that is closed on Sunday and Monday. (These are the non-business days for DeWayne's business.) In that case, you could calculate the date that is five days before the the first business day of the month with the following:

```=WORKDAY.INTL(A1-DAY(A1),1,2,MyHolidays)-5
```

In this case, if the date in cell A1 is still October 10, 2022, then the first business day of the month would be October 1 (a Saturday, which is a business day for DeWayne's barber shop), and five days before that would be September 26.

Note the addition of the third parameter, in this case the value 2. This value indicates which days of the week are your non-workdays. The value can be one of the following:

Value Non-Workdays 1 Saturday/Sunday 2 Sunday/Monday 3 Monday/Tuesday 4 Tuesday/Wednesday 5 Wednesday/Thursday 6 Thursday/Friday 7 Friday/Saturday 11 Sunday 12 Monday 13 Tuesday 14 Wednesday 15 Thursday 16 Friday 17 Saturday

Other than the added third parameter, the WORKDAY.INTL function works the same as the WORKDAY function.
