Given that this group has experts on the calendar and the earth’s

1. Assuming that I was living a 1000 years ago, and had unlimited time
watching the sun and stars (and *without prior knowledge*) how would I
notice that each year was growing by about a quarter of a day?
Are you talking about the quarter day drift that would happen without a
system of leap years, and do you have a calendar of 365 days? In which
case, the solstice dates would very obviously gradually migrate through
the calendar - I day per 4 years (give or take an extra 11 days over a
couple of millenia).
