Shalom David,
    Something in your post sticks out like a sore thumb to me.  It is this:

    "My Days shall be as your days"

     I have been watching the same Shavuot date as Arlene on the 5 doves site for something BIG to happen.  Even though others are looking at the Hillel Calendar date for Shavuot...there is just a little nagging Spirit within me that says to count the Omer on the Biblically Correct Calendar.
     Now, I am wondering if that is what the phrase above is pointing to.

Talk about an unknown day...this years calendars make all the Feast Days fit into that catagory.

     Here is something else that is nagging in my Spirit....remember the 1260...1290...and 1335 days of last years Spring Feast season....all falling on certain Feast Days.   Could it be that, that was a heads up sign for what was to transpire this year on the Calendar.  So that we would be cognisant of the exact days being 1 year apart..this year?   If we use the Hillel Calendar there are about 30 extra days to each of these days mentioned in Daniel.  But as Dave Camp has noted....the Biblically Correct Calendar lines up perfectly with the Heavenly Calendar.  That is "My days shall be as your days".

This is just thoughts,
Miriam Brown
