Question

What is the actual date without leap years and daylight savings?

Answer 1

If you suggest that the Julian calendar reforms would have introduced the 365 day-year, in 45 B.C. as it actually did, but with no leap days at all, we would be long by either 516 or 517 days (still depending on whether there were 12 or 13 leap years before 1 A.D.) and we would be on 6 or 7 June 2018.
