Fortnite 14-day calendar?

Since yesterday, there are the 14-day calendar. I'm currently not at home and can't gamble. Meie question is now how long I have time to make the challenges to pick up the gift. Can't I get the reward of today, eg tomorrow?

You have time to face the challenges until January 1, 2019. You can, for example, on the 30th of December Still the challenge to make December 1, so no stress. The important thing is that you do all before the 12 days are around.
