Counting months between dates across multi-years

Jessica Abbey · 03/31/22

How can I calculate out how many months between 2 dates when the dates are in 2 different years?

I see you marked Dale's comment as not resolving your question.

Another way to do this is to find how many days there are between the two dates, divide this by 365 (years) then multiply by 12 to find the Months.

=ROUND((NETDAYS([Start Date]@row, [End Date]@row) / 365 * 12))

Cheers,

Genevieve

@Jessica Abbey Not to over-simplify, but you have to count years and months!

=(YEAR([Date 2]@row) - YEAR([Date 1]@row)) * 12 + (MONTH([Date 2]@row) - MONTH([Date 1]@row))

should be pretty close.
