One of my favorite sites is FREEDOM FROM RELIGION FOUNDATION
Dan Barker, one of the founders of that organization, offers a reasonable question to Christians about Easter in his book Losing Faith in Faith:
"My challenge is simply this: tell me what happened on Easter. I am not asking for proof. My straightforward request is merely that Christians tell me exactly what
happened on the day that their most important doctrine was born." (Chapter 24, p.178)
He goes on to explain the conditions of the challenge are simple and reasonable, referencing the four gospels, beginning at Easter morning and reading to the end of the book: Matthew 28, Mark 16, Luke 24, and John 20-21. He says Acts 1:3-12 and Pauls's version of the story in 1 Corinthians 15:3-8 should also be included in the 165 verses, which can be read "in a few moments."
He then asks Christians who accept his challenge to "write a simple, chronological narrative, without omitting a single detail from those separate accounts, of the events between the resurrection and the ascension: what happened first, second, third, etc., who said what, when, and where these things happened." (same reference.)
Mr. Barker allows for educated guesses in the times of day of the narrative, and anyone accepting his challenge doesn't have to present a perfect picture. He does state emphatically that "not one single biblical detail be omitted." (same reference.)
Mr. Barker says he has tried the challenge himself. AND FAILED.
