Counting number of times a deadline is missed

I need a formula for a sheet summary that I just cant wrap my head around, might even be two formulas working together...Maybe I am over thinking it.

I need a formula to look at a "date1" column and a "date2" column on a sheet and then I need it to count the number of times the difference between those two dates is more than two days (two working days, Mon-Fri). Essentially it is just counting the number of times a two day deadline is exceeded.

Any thoughts would be appreciated. Thanks!

    Add a help column "Networkdays" with this column formula, then hide it

    =NETWORKDAYS([Start Date]@row, [End Date]@row)

    Then in your sheet summary

    =COUNTIF(NetWorkdays:NetWorkdays, >2)

    Hi @Dan Bourque

    I hope you're well and safe!

    Here's a possible workaround or workarounds

    • Add a so-called helper column that references the dates in the sheet summary and then use a Workflow combined with the change cell Action to register each time it changes or have a copy row Action copy the row to another sheet and then count how many times it's been copied.

    Make sense?

    Would that work/help?

    I hope that helps!

    Be safe and have a fantastic week!

    Best,

    Thank you, that seems to work well! However, what if I added another variable. With the "date1" and "date2" columns I mentioned, sometimes in our process the "date 2" field will not be used. So in the Summary it will error out because it sees the blanks.

    I cant seem to get the IFERROR function to work in the helper column, I want it to give me a "0" value if it doesn't see a date in that column instead of the invalid data type that throws off the summary. Thanks again!

    I see now that I assumed incorrectly that you wanted to measure it on row by row basis.

    the iferror should look like this

    =IFERROR(NETWORKDAYS([Date1]@row, [Date2]@row), 0)


    another possible way

    =IF(ISDATE([Date2]@row), NETWORKDAYS([Date1]@row, [Date2]@row), 0)
