The tropical year, on which our solar Gregorian calendar is based, is 365.2422 days. Was it always so? I am wondering if in a previous era (about 3000 years back) it could have been 365.14 days.

No, Im not doing a "Velikovski" who suggested a 360-day. Such an idea was obviously too big a variation. My suggestion would only be 2 hrs, 27 minutes per year. Would that be feasible? Any thoughts?
