In reply to your 7/28 post Donna Danna: "When the Feast of Firstfruits Occurs" Letter (fivedoves.com) I thought you might be interested in reading the link below which is an explanation of why some Christians believe the Firstfruits of Barley the sheaf of wave offering of barley was made during the week of Passover and not on the 22nd day, the day after Passover week was over.  It's probably not going to change your belief that the Feast of Firstfruits happens on Nissan 22, but because I have never heard this explanation before, I thought I would pass it along to you for consideration,
