I think it does'nt lead to the 7th december. It leads to the beginning of the 8th december.
I think, this countdown is not made for germany, it is made for the international date line (in the Pacific). Look here: time zones.

From now on, in 3 days+11h:58m we have December 8th, 00:00:01 o'clock.
And on december 8th is what? ... the public holiday "Maria Empfaengnis" (the Immaculate Conception of the virgin Mary - a dogma of the Roman Catholic Church).
