Filtering a view in SharePoint list based on a year

Question

I'm using SharePoint 2010.

I want to create new view for my list. The list contains a column called Year, which is a number and contains, as name suggests, year. Eg.:

2012
2011
2010
2009

I would like create a view, where I would display only last 3 years. Under creating new view, I go to Filter, choose Show items only when the following is true:, pick column Year and... this is where I get lost.

How to write a condition, that a number should be greater that current year minus 3? I tried

[Year]-3

but this obviously couldn't be so simple. Please help me write this condition.

Answer 1

[Today] returns the current date so you can use the following formula:

[Year] > YEAR([Today])-3
