在 Google 表格的日期列表中计算一个月的实例数

Question

I have a large spreadsheet containing job information. I am trying to make a "Job Count by Month" field, and it doesn't pull correctly.

My Job Info is all located in a sheet called "3PL Jobs". I have a hidden sheet titled "Under The Hood" which contains a table of months next to their names (ie 'Under The Hood':E2,E13 is a column of numbers and the F column has the corresponding "January","February". etc.

I've made a cell with a dropdown list of the months (pulling from the Under The Hood sheet) and in the cell directly to the right I want it to output the number of completed jobs.

I got this working with the dropdown month list being just a simple list of numbers and not the name, but it looks awful so I was hoping to use an index match to be able to use the name.

This is the code that worked with a list of month numbers, using I19 as the entry cell for the month number

=COUNTIFS(ARRAYFORMULA(MONTH('3PL Jobs'!C3:C)),I19,'3PL Jobs'!AR3:AR,"COMPLETE")

This is the code I've tried to include to index/match the month name (this in theory should just output the month number based on the name selected in I18, but it outputs "8" no matter what is selected)

=arrayformula(index('Under The Hood':E2,E13,MATCH(I18:'Under The Hood',F2:F13),1))

I'm sure I'm missing something simple, but this is driving me nuts!

Answer 1

to turn month name into month number all you need is:

=MONTH(I18&1)
