> the Julian calendar that added June and July as months

Usually this piece of incorrect trivia is cited as July and August, but regardless, it was January and February that were added to the end of the calendar. July and August were always there but were renamed. And the Julian calendar didn't add or rename anything.

Oh, and the Julian calendar had leap years too. The Gregorian calendar didn't add leap years, it took some away.
