Question : Selecting certain items

Hi, I'd opinions on how to best tackle this issue.
I have 12 option buttons, I for every month of the year. This is NOT an option group.
The user can choose more than one month. However, heres how I would like this to work
eg. If they choose May and then Aug, I want code to also select the months in between, so in total May, June, July and Aug should be selected. So you can imagine the combinations.
This is very similiar to selecting something in a listbox, Holding down the SHIFT button, selecting something else, and everything in between gets selected as well.
Should I create a collection of these items, or an array.
Whats the best way to approach this

Here in a database showing how to do it.

Note: Radio buttons usually indicates an option group. I would suggest checkboxes instead.
