"But you, Daniel, close up and seal the words of the scroll until the time of the end." - Daniel 12:4
I find all of this fascinating. I have written something on my blog www.lighthousevision.blogspot.co.uk sometime last year called 'Let us make man in our image'. I believe the scriptures show one day as a thousand years with God, Jesus coming like the sun (which came into being on the 4th day according to Genesis), the moon which is described as 'a faithful witness' which also came into being on the '4th day' is like the church which has no light of its own but can only reflect the light of the sun (Jesus). There are two creations, one on the second day and one on the 6th day, the one on the sixth day refering to mankind (plural) being created in their image ( I believe that to be God and Jesus, who is the second Adam ). Your calendar has added to what I believe is shown in the scriptures.
