A holiday or day that starts with "A"?

Okay, I have this project and I have to come up with a thing to remember sine, cosine, and tangent. Here's mine, "Ophelia harvested amaryllis honey on _____."





I need to come up with a one word day or holiday or anything that sounds in place... and please, NO ARBOR DAYS!





ALSO- Does any one here know any cool girl names that begin with "O"?





~Thanks You Guys! ^.^
