The Jewish calendar has none of these.
here is a good explanation of the Jewish calendar.....

as far as my prefrence, I live in the USA and there is only 1 calendar here and that is what I use. I just choose to not refer to Jesus as "Christ" because it goes against what I believe in. I posted earlier that if I was Christian I would use BC/AD but because of my faith I do not. An example would be 2004 A.D.M.(Mohammed) how would that make you feel? (Not that I equate Jesus whom I look upon as a righteous man, a rabbi and a scholar as the same as Mohammed), but I do not see either as more than mortal. Please do not be angry about my example there is no equating the 2

I think it very significant that Christ is the great benchmark of human history. Modern Jewish theology holds that the Messiah is only a natural man. Rabbis claim the Messiah/Christ is not the Son of God, or divine in any sense. I couldn’t disagree more.
A bit of theology on Gen. 3:15. The progenitors of the human race sinned in the Garden. A prophecy (Gen. 3:15), the first prophecy of the bible, was then given, the scope of which is the general history of man. Sin brought the need for messianic redemption. The Messiah is not just a Jewish figure, we all need a savior.
The prophecy, in symbolic representation, was about the “seed of the woman,” i.e., Christ. Supernatural birth is indicated, the virgin birth, women do not have “seed.” The “seed of the woman” would not have a natural father, he would be the Son of God.
The heel and head in the prophecy: Christ would suffer in the fight for our redemption, his heel would be wounded in the struggle with the serpent, the enemy of our redemption. However the serpent gets his head stepped on. The contrast in the head and heel is one wound is fatal, the other is not. Mel Gibson’s “Passion” was about the suffering of Christ, not fatal, however. Christ defeated sin and the devil bringing redemption for all of us descendants of Adam.
So the scope is bigger than just Jewish Messianism – you mentioned Islam, certainly bigger than any “Mahdi” or Messiah they may come up with. There has only been one born without a natural father, Christ, the Son of God, He trumps every Messiah that man might come up with. No need to look for another “seed of the woman,” He has already come. What Christ wrought was the central event of human history, central to Jews, Christians, Muslims, whatever. Took a while to get here, but maybe you can see my point on why I believe Christ’s death and resurrection 1,970 years ago is the rightful, predestined by God, benchmark of human history.
