Yep its the same on the UK and DE version
Infomation from the DE forums
"But take a look at the duration, it doesn't end on December 24th, but on December 26th, so that if you don't manage a task, provided that there are not too many coin tasks now, you can still do it despite leaving it out. In the course of the day I will reopen the thread for a new attempt to see whether the discussion is objective and in a decent tone."
There is 6 days and 13 hours left meaning
13 hours to do todays task - 1
1 day - 2
2 days - 3
3 days - 4
4 days - 5
5 days - 6
6 days - 7
So there is actually from my understanding, 7 more tasks to go so if you have done all the tasks to this point you will still be able to get the 24th day.
