There seems to have been signs over history that point to the Gregorian Calendar being incorrect and against the will of God.
Here are a few examples:
The Eastern Orthodox Patriarch of Constantinople transitioned to the New Calendar (Gregorian Calendar) in 1923, he also moved Pascha to the New Calendar date. However, the miracle of the Holy Fire did not occur that year according to the New Calendar date in Jerusalem, it occurred at the Old Calendar date. The Holy Fire happens every year to this day on the Old Calendar’s Pascha. It never happens on another date.
On the Feast of the Exaltation of the Holy Cross; the celebrants of the New Calendar folks were already finished commemorating the Feast, but 13 days later, those who refused to transition to the New Calendar, were having the Feast according to the ancient calendar. And on that day, a cross appeared in the sky, and it was witnessed by the faithful who were gathered.
Is this an indication that the Gregorian Calendar is wrong?
