Excel Month difference count?

[Django x2]

Hi guys,

I have a spreadsheet with 3 columns. One is a start month, the other an end month. The 3rd needs to show the difference in the number of months as a figure. So, say col 1 had April, Col 2 had June, col3 shows "2"

Dooable?

Yeah, not spanning years, just 12 months from jan to dec in any given year
