Date Calculation

Manuel Arrington

=IFERROR(NETWORKDAYS([NAI Project Start Date]7, [NAI Project End Date]7), 0)

Cannot get this to calculate

The first field has =Another_Cell but the property is set to date. Is this the problem?

Im testing the date in the C1 field for being a date with NOPE being the return if its not a date

Hi Manuel,

I think that the columns you've got dates in isn't set to a Date column type. Try right-clicking the column header and selecting Column Properties, then switching them both to Date type columns. Leave the column you're putting your formula in as a Text/Number column.

So, I found that the date entry in the first column of 7/1/2018 is not a date. I changed it to 7/1/18 and I got further with the calculation.

Both Columns are set to date. Interestingly I changed all of the 7/1/2018 to 7/1/18 and some work now and some don’t in the Networkdays calculation. Getting invalid type on some entries.

You are getting #INVALID DATA TYPE even after using IFERROR()?

NETWORKDAYS throws an error if either date is blank.
