Formula is including dates when adding row

[easybpw]

Hello,

Thanks in advance for your help. I have a formula that is including dates when it sums toe row. For example if the formula is =sum($a2:$z2) and in column n2 is a date the formula is including that in the results which then increases my result. In my example, without the date the result should be $15,450 but if I include a date in n2 (7/27/18) it changes my result to $58,758. N2 is formatted as a date. How do I eliminate the date in n2 from the result without having to change the formula to be =sum($a2:$m2)+sum($o2:$z2)?

Thanks!

Bill

It is important to understand how Excel stores dates in Excel. They are really just numbers with Custom Formats.
Excel stores dates as the number of days since 1/0/1900, and time is a fraction of one day (if you convert any valid date entry to the General or Number format, you can see this easily).
Formulas in Excel do not care about the formatting, only the underlying value. Since dates are numbers, they will be picked up in SUM formulas.

By the way, you could simply use:

[COLOR=#333333]=sum($a2:$z2) - $n2[/COLOR]
