Disillusioned JW:
The WT has written that about the year 30 C.E. a number of Jews were expecting the arrival of the Jewish Messiah, and that such expectations were based upon their calculations of the 70 weeks prophecy in the book of Daniel. [Is that a false teaching of the WT or were Jews back then really doing such?]
The Jews were always expecting a messiah at some point, but the notion that they were especially expecting one around 30 CE or that it was because of anything in Daniel is a Christian tradition. (Also, Jesus’ ministry would have run from 26-30 CE, and the JW dates for his ministry are also dogmatically asserted based on their interpretations of the ‘70 weeks’.)
