I answered that in post #165: "The burial would have to have taken place no later than the 5th day of the week."
That would be a problem because numerous passages indicate a Preparation Day burial, or the day before the Sabbath.
Under the assumption that:
Day 1 through Day 7 of Creation began a never ending cycle of 7's, or weeks (which is what most Christians, Jews and Muslims believe)
Then a 6th, or Preparation Day, Burial would have Christ arising on the Day we call "Tuesday", which happens to be the 3rd day of the week.
Tuesday is the 3rd day of the week, which falls after 3 days and 3 nights from a Friday burial.
Saturday night - 1 night - beginning of Sabbath
Saturday day - 1 night, 1 day - Sabbath day
Sunday night - 2 nights, 1 day - start of the first night/day period of the week
Sunday day - 2 nights, 2 days
Monday night - 3 nights, 2 days - start of the second night/day period of the week
Monday day - 3 nights, 3 days
Tuesday night "while it was still dark" - the start of the 3rd night/day period of the week.
Right here is where all the time frames fit together. For Christ not only said that He would rise "after 3 days and 3 nights" but also that He would rise "the 3rd day".
So is Tuesday the day of Resurrection? Yes and no. Curiously enough, days of the week, excepting Sabbath, are not named in the bible. There is only a reference to their numerical place. In order to find any day without the use of humans, or human devices, one would need to look to the heavens.
So we should not be under the assumption of ever cycling 7 day weeks from Creation. For if a man is lost in time, he cannot find out what day it is without consulting another man, or some man made device. This would have been a big problem for any person, especially in former times, who happened to find themselves without another person to consult if they didn't know what day it was.
God created the moon for this purpose. It says so right in Genesis. It marks the "appointed times" of which the Sabbath certainly is.
