When should Cid be used, and when should Cis?

I noticed many volumes using one or the other, and some even using both. I have only been able to find 2 differences, but feel free to tell me if there are more.
 * Cis displays the Title of the 1st Story
 * Cid can handle both Month and Season, while Cis only displays Month
