Hey veracious-—
The Gregorian calendar has and had nothing to do with the Holy Roman Empire. It was introduced in 1581 by Pope Gregory XIII as a mathematical and astronomical improvement on the previous Julian calendar, and us still recognized as such today.
The Pope had legal authority to “impose” it only on the tiny Papal States, not on the Holy Roman Empire. However it was quickly adopted by most Catholic European countries because it set the date for Holy Week-— and they all wanted to observe the Pasch on the same calendar.
Appreciate your inputs. Our calendar is a Roman calendar. The Roman empire became the Holy Roman empire. They are one and the same. As a matter of fact the same _empire_ exists today as the EU with NATO as it’s army. There is a spirit over the Roman empire; there is a spirit, actually a principality represented by each biblical empire. Those princes did not vanish just because the empire seems to have. The amount of power each empire has is a function of how immersed the people of the respective region are to its prince. All of these empires are resurrecting in power as the Word says they would. Their princes have strong support by mankind in those regions. The combination of them all is mostly described as Babylon in Revelation.
Principalities occupy territory, like the Prince of Persia. This prince is the power behind Iran and is definitely empowered by its peoples support.
Hope this helps...
