> By the time of Julius Caesar, the solstices were on the 25th
That is false. See https://kiwihellenist.blogspot.com/2022/05/julian-calendar.h... , or "Digression #2: why do Roman writers report the date of the solstice as 25 December?" at https://kiwihellenist.blogspot.com/2015/12/christmas-and-its... .
Solstices were on the 25th a few hundred years before the time of Julius Caesar. He did not even attempt to put them back there.
The Gregorian calendar has not restored the time of Julius Caesar, but the time of the First Council of Nicaea (325 AD), when the rule about how to compute the date of the Easter was established.
From the time of Julius Caesar to 325 AD, more than 3 days of drift had accumulated, so the Gregorian calendar would have required 13 or 14 days of correction.
When many countries transitioned to the Gregorian calendar much later, they had to add additional correction days to the initial 10-day difference, about 1 day per century.
