I'm going to presume that the dates are converted to the standard that
all the others are based on: The Julian Calendar that modern astronomy
programmes work on. And that they have been worked backwards to allow
for that deviation as I hope had the OP's quote.

Modern astronomy programs don't work on Julian. Old Style is Julian,.
New Style is Gregorian.
