Kuddos to Bob Ware for finding 234 days from the beginning of the Hebrew year 5766 to Ascension Day, 5/25/2006, Iyar 27, 5766.

Also note that Ascension Day 5/25/2006 brings to an end exactly 40 Hebrew years, counting inclusively from Jerusalem Unification Day, June 7, 1967, Iyar 28, 5727, at sundown in Jerusalem.

(Realize that it is counted as 39 years if you count starting at the number "0".  However the "0" wasn't "invented" till well after the 1st century so there is much debate whether it is proper to apply a "0", hence the reason to count "inclusively".)
