Winterfest is Fast Approaching! Are You Prepared?

Hello everyone!
December is here, and that can only mean one...

Hi. What is winterfest? Is it a competition?

Well, it's that and a whole lot more. Be sure to check out your Winterfest advent calendar, too. A link is provided on the homepage.

I don't understand the calendar. I click on a picture and it takes me to my account page.

It does that to make sure you're...

It does that to make sure you're logged in and to show you whether you got an achievement, I guess. All the visible tiles have the same link.

For some reason I'm getting all the achievements so far despite missing a few days.

hah

Cmon, of course I was logged in (I posted that comment). And also, like I said, it takes me to my account page, not the login page.

I mean, it seems like the calendar isn't integrated into the rest of the website in a certain way, so it won't pay attention to whether you're logged in, hence the message above the tiles. The forums and your account page know if you're logged in regardless of whether you did so since opening the browser, thanks to cookies.
I don't think it's necessary to go to your profile or the calendar everyday, really; although I checked the forums everyday, I didn't check those two pages until the third day but still got the first two achievements (which are labelled as having been gotten on the third . . . so that's weird).
