Not only the things you mentioned, but also consider this.  Spring equinox is March 21.  When the heavenly visit to answer Daniel's prayer in Daniel chapter 10 occurred, Daniel found that the messengers actually started their journey 21 days before they arrived.  I believe that Daniel 10 is a picture of both the resurrection and the rapture in the experience of Daniel at the time of the arrival.  So, add 21 days to the Spring equinox and April 11/12 is the result.

Also, if one takes the 1,260 days of the first 1/2 of the 70th week of Daniel and subtract the remaining days after the 372 days left after April 4/5 this year, the result is the GEMATRIA OF JESUS...888.

EVEN SO, COME LORD JESUS!!!
