About Quick Time Period Calculator

I often have a situation like, "What's 6 months from now? I need to book another appointment". Or, "Sure, let's touch base in 3 months time". And every time I have to Google, "What's 3 months from now", click another link, enter the values, etc. HEADACHE. So I created a extension that I could quickly click.
