So, I was thinking about something more general and I found it

An event for the most of the European countries. I have already one more event in mind which could be connected to this one.
A new calendar
Conditions:
1. The year is at least 1580 (historically it was in 1582, so this is rather small change)
2. Administrative power of theruler is at least 3
3. The state religion is any of the christian religions (maybe even without orthodox, that would be more historical, I am open for discussion)
4. One of the following is true:
4a: Administrative power of the ruler is at least 4
4b: Relations with the Papal state are at least 50 (I think I hear max is 100, if it is 200, then the value here would be 100)
Text:
Julius Caesar did enforce the reform of the calendar in 46 BC. Julian calendar had 365 days each year and every for years it had 366 days (thi year was called Leap year). It was first used in 45 BC. Although everything seems alright, this calendar still wasn´t perfectly precise. The calendar gained about 3 days every 4 centuries. In the 16th century, the shift was too big to be overlooked. The society was still connected to agriculture and this shifts in calendar mean nothing but troubles. The pope decides it is time to change and had established a new calendar. In this calendar, some of the leap years were removed (specifically those which ended by double zero and their first two digits were divisible by 4, for example the year 1600), so the shift was only 1 day every 3600 years. This calendar was working with the idea of heliocentrism, so purely out of practical reasons, this idea was accepted as a theory.
Choices:
A: This is just what we needed!
B: Nah, those thing cannot be trusted.
Consequences of different choices:
A:
+10% Production Efficiency untill the end of the game.
+2 Revolt Risk for 10 years.
B:
+150 Gold
-1 Revolt Risk for 10 years.
If the B is chosen, there is a chance to another event to fire.
Spreading of the new calendar
Conditions:
1. The Year is at least 1640
2. Administrative power of the ruler is at least 3
3. The event “A new calendar” was rejected.

Although heliocentrism was signed as herecy, the new calendar did survive. Now, still more and more states are using it and having benefits from it. Shall we also introduce it?
Choices:
A: It is a good thing, results are not lying.
B: We shall stick to the tradition.
Consequences of different choices:
A:
+5% Production Efficiency until the end of the game
+1 Revolt Risk for 5 years.
B:
+200 gold
