Excel/Subtracting a fix number of days from a date, without weekends


What is the formula to subtract fix amount of days from a date, excluding Jewish weekends (Friday, Saturday).
For example: May 10 2015 minus 2 days = May 6 2015.

ANSWER: This used to be quite tricky, but is now easier thanks to the workday.intl function - if you visit you will see how this works.  NOTE that this was introduced in office 2010, if you have an earlier version then a more complicated formula would be needed.

QUESTION: Thanks Aidan.
I believe that the workday.intl function counts the number of days between two dates.
However, I wish to have the date, if you subtract X days from a specific date.
For example: 12/05/2015-1=11/15/2015.
Any idea?

I very nearly gave you the wrong answer, which would have been networkdays.intl - it is this that counts days between two dates.  From the site I referenced

The Excel Workday.Intl function returns a date that is a supplied number of working days (excluding weekends and holidays) ahead of a given start date. The function allows the user to specify which days are counted as weekends.

The function is new in Excel 2010 and so is not available in earlier versions of Excel. However, it is similar to the Workday function, which is available in earlier versions of Excel.

That description is actually wrong, as they specified AHEAD of a given start date - but as you can use negative numbers, the formula wiil work for ahead of or before

so if your 12th May was in A1


would give you the result you wanted.
