The classical Greeks likewise had not solved the problem of how long the
year is, though later Greek science was able to establish a whole bunch of
stuff ...

It's me once again. With the reservations I have expressed before, there's no denying that the "later Greeks" were very smart indeed. The length of the tropical year calculated by Hipparchus in the second century BC differed from modern measurements by less than seven minutes. (The error would have grown to an hour in nine years and to almost five days in a thousand years.)
