Change Cell Contents if Cell Date is in Previous Month / 4 Months

[Mazzic]

Good morning!

I have a layout that looks like this:

For one criteria, I would like to:
Display QUAL if the date is in the current or previous month.
Display NC/QUAL if the date is before the previous month.
Display UNQUAL if the date is blank.

For a different criteria, I would like to:
Display QUAL if the date is from May/June/July/Aug OR if the date is in Sept/Oct/Nov/Dec
Display NC/QUAL if the date is prior to May
Display UNQUAL if the date is blank.

Thanks in advance!

One example for any of these would probably be enough for me to figure out the rest.

For the first part what happens if the date is in the future?

 

[Mazzic]

The date entered should never be in the future based on the way the spreadsheet works, but in a formula case QUAL would be acceptable

 

[Fluff]

In that case how about
=IF(A2="","UN",IF(MONTH(TODAY())-MONTH(A2)>=2,"NC/",""))&"QUAL"

That works perfectly - truly impressed with your solution!

Looking to decipher your formula so I can re-arrange it based on the other parts of my spreadsheet, if the date range is blank, it returns UN. if the month of the date is either today's month or today's month minus two months, it returns NC/, and it always returns QUAL. Right?

I would recommend using the DATEDIF function (https://exceljet.net/excel-functions/excel-datedif-function) instead of MONTH in case your dates aren't in the same year.
For example, let's say we were in January, and looking back at November or December dates. Substracting MONTHs will result in negative values.

You've understood it correctly.
Although as Joe4 has pointed out, I didn't factor in changing years.
