What's the date?

It's been a while since I've seen the series, and I can't remember if you get to know the date. I know it's the year 2525, but what of the month? I've read the book and searched http://halo.wikia.com/wiki/Main_Page. I'm guessing that the suit that MC is using is the MJOLNIR Mark IV Powered Assault Armor - http://halo.wikia.com/wiki/MJOLNIR_Powered_Assault_Armor - which was put on the field November 27, 2525. I'm just asking because I hope that the date of the attack in FUD was after that date.

P.S. I know, I'm a nerd. And proud of it! :)
