BTW -- More than likely Matthew 26:7-12. Kings were anointed on their heads, but Jesus said that she had done this "to prepare me for my burial". He was headed for death [Daniel 9:26 -- Messiah shall be cut off] .
That's a good way of putting it, yes. The estimates I've read is that they presently number about 30,000 worldwide. So it is a pretty small movement, although they do have a presence in Israel, and a center in San Francisco. I am not an orthodox Jew, and I do find some of their critiques of certain rabbinic teachings intriguing. But I don't agree with them on everything.
Unless I am misunderstanding it, in the Karaite calendar, there would be aas many as 11 days per year between the end of Adar and beginning of Abib that would never be counted or have a date assigned to them. Hopefully during that time nothing dateworthy ever happened.
I believe you are right. History did move at a slower pace back then!
