Recently I have been using more dynamic array formulas and have come across an unusual situation where a date is not treated like a date.
Remember dynamic arrays are currently only available in the subscription version of Excel.
Have a look at the image below.
You can download the example file at the button at the bottom of the post if you want to see it in practice.
Cell B1 is an input cell to set the first date of the sequence.
Cell E1 creates sequential numbers using the SEQUENCE function.
Row 2 has the dates and is formatted as a date.
Row 3 is the problem. If I try calculate the number of calendar days in the month using DAY and EOMONTH functions it gives a value error as if the entry in E3 is not a date.
If I multiply the E2# reference by 1 it fixes the issue as per row 4, but I shouldn’t have to do that.
I have had this is other cases where a number is not treated a number until you multiply it by 1 or perform a calculation with it.
Not sure if anyone else has seen this?
If you want to learn more about dynamic arrays I have a free Webinar Recording plus a pdf manual at the link below.
