Please explain the discrepancy between the Jewish (5756 presently) and Western (1995) calendars. Also, how did the term, “before the common era” (B.C.E.) originate?
To answer your question, the reason there is a difference between the Christian and Jewish calendars is because the Christian (or Gregorian) calendar tries to begin with the year of Christ’s birth, though they missed it by about six years. Based upon that premise, it is probably six years later than our calendar indicates.
The Jewish calendar is based upon rabbinic calculations from Creation and, so, the rabbis believe that Creation occurred 5756 years ago. Just as the Christian calendar is off by about six years, the Jewish calendar is off by about 250 years. It is really about the year 6000 since Adam was created. That is the reason for the difference in years and neither calendar is 100% accurate.
The references of B.C. (before Christ) and A.D. (the year of our Lord) are based upon the Christian dating system. This creates a problem for Jewish people who prefer not to use references to Christ, so they opt for
