AnswerMug Challenge Series, Abbreviation Alteration Edition:

Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec

Take each of the abbreviations above and write an English-language word that begins with the same three letters shown, and the order of the three letters cannot be changed.
Your answers cannot be the actual months for which the abbreviation stands, nor can they be other definitions of the word for the month, such as march, may, or august.
Proper names of people, places, or things are allowed.
Spelling counts.
A twelve-part answer is what I’m looking for here, but if you can only do a few of them, that’s fine.
You cannot use any word that has already been used in this thread.
The first of you who posts a twelve-part answer that meets all of this criteria will garner 500 AnswerMug points from my account to yours, and each subsequent person who posts a correct twelve-part answer will garner 200 points.
No one member can be awarded points more than one time.
