I’m endless in math, yet gone in a bite, I’m sweet after dinner, or circle’s delight. One you can savour, one you imply Both share my name, what am I?

I'm thinking of a number between one and ten, I'm not fIVe, but don't worry, you don't have to go on a whim

There isn’t one this year. There wasn’t one last year and there won’t be one next year. But the year before and the year after, certainly. Twenty-four hours added for free, you should jump at an offer like that.

A good one may contain ambiguous clues, but possesses a single answer that often provides an ah hah for the solver. It may incorporate an anagram, an acronym, or another word puzzle. It may misdirect the unwary, but provide guidance to the thoughtful. It should avoid typos, misspellings, and poor grammar, unless those are part of the clues. It is best to avoid repeating common answers, or failing that, the clues should be novel and creative. Thank you to all who create these types of posts and those who attempt to solve them.
