Ah now! If we're going to bring it down to specific days... 
Funnily enough, I was going to mention the Rush song, Lakeside Park, which I have on one of the best live albums ever, imo of course. I knew a month was mentioned, but couldn't remember which, and couldn't be ar*ed putting it on. Then it came to me, as I was singing it over and over in my head when I should have been concentrating on driving, that the month is May, and a specific day is mentioned there as well, 24th of May I think.
But May has already been claimed (by me I hasten to add)
PS: Why use one word when you can use a load?
