That's a bit vague. :) You're saying the "spring equinox in late
March" was already a tradition on the old Roman calendar (even if
political manipulations of intercalation had prevented it from being
reality for a long time)?

Hm. I thought archaeological discoveries had pretty much established
the observed new year sequence (under the erroneous interpretation of
the rules) in the early years of the Julian reform and thereby placed
the first observed January 1 of the Julian era (45 BCE) on the
*previous* proleptic Julian date: BCE 46 December 31 =JD 1704986.

Ah, an upper bound. That makes sense.
