Great GIft Pile Question

These achievements are THE achievements.

It's for other days. Each day the achievements/goals to get a new gift/coal will change.

So... I'm a little confused. I won Assassins Creed Revelations... do I get to keep it? I hit Unpack gift, and it's in my Steam library now and doesn't have like a days counter, like a guest pass would, but it all happened so quick I'm surprised. And it's still in my gift inventory to Send or Unpack, even though I've hit Unpack numerous times.

Basically: I'm confused.

Day 1 is ending soon, could I still get the achievements and the free gifts/coal that would come with the achievement if I finish on some other days like Day 2 or Day 3?

You'll have all sale, just like in summer to catch up.
