I want to add up numbers that only happened within the last 12 months from
the current date. I do have a column with the date I want to reference to.


If your column of dates is named "dates" and your column of numbers is named
"numbers" then:

A1: StartDate of period of interest
A2: EndDate of period of interest

=SUMIF(dates,"="&A1,numbers) - SUMIF(dates,""&A2,numbers)

should do it.
