This might seem like an unnecessary question because of 1 Corinthians 15:4 but please bear with me.
Most people do not study Judaism, and therefore their INSIGHT is limited. They take this verse, and assume it is talking about JESUS being crucified on Friday, when HE WAS NOT.
John 19:31 (HCSB)
31 Since it was the preparation day, the Jews did not want
the bodies to remain on the cross on the Sabbath (for that Sabbath was a special day). They requested that Pilate have the men’s legs broken and that ⌊their bodies⌋ be taken away.
HOW MANY SABBATHS ARE THERE DURING THE WEEK OF PASSOVER? That is not a trick questions, but only when you study Judaism will you LEARN the Truth. There are
2 Sabbaths during almost every Passover Week. Only when the Jewish calendar (not the same as a Julian Calendar) rotates so that the SEVENTH DAY OF PASSOVER, which is also called a SABBATH, falls on Saturday, is there NOT
2 Sabbaths during the Passover Week.
When the SEVENTH DAY OF PASSOVER, A HIGH HOLY DAY also CALLED A SABBATH. WHEN IT FALLS ON FRIDAY, the Day of Preparation (when the Food for the SABBATHS must be Prepared is THURSDAY). They have to make enough food for BOTH OF THE SABBATHS BACK TO BACK. Yes, I know that there is differences of opinions on which day JESUS was Crucified, BUT THIS ONE MAKES PERFECT SENSE TO ME. Therefore, JESUS had to be Crucified on the Day of Preparation, Thursday, followed by BACK to BACK Sabbaths.
Remember THEY WERE IN SUCH A HURRY TO GET THE BODY DOWN FROM THE CROSS, that they DID NOT have time to wrap the required SPICES in the Linen Shroud, and therefore the women would come back AFTER THE BACK to BACK SABBATHS early on Sunday Morning on the Day after the Weekly Sabbath to put the required spices in the Shroud. SO IT WAS RIGHT AT SUNDOWN ON THURSDAY, WHEN HE WAS LAID IN THE TOMB.
NOW COUNT THE DAYS, and remember that IN JUDAISM A DAY BEGINS AT SUNDOWN, AND ANY PART OF A DAY ALSO COUNTS AS A WHOLE DAY. I will also count the way we are used to in order to count it, even though Sundown Thursday is actually Friday according to the JEWS.
ONE NIGHT - STARTING THURSDAY AT SUNDOWN
ONE DAY - FRIDAY SABBATH (SEVENTH DAY OF PASSOVER)
TWO NIGHTS - STARTING FRIDAY AT SUNDOWN
TWO DAYS - SATURDAY (THE WEEKLY SABBATH)
THREE NIGHTS - STARTING SATURDAY AT SUNDOWN
THREE DAYS - AND REMEMBER IN JUDAISM ANY PART OF A DAY, COUNTS AS A WHOLE DAY.
So the women came with their Spices "Very Early in the Morning", and the Angels appeared to them.
Luke 24:1-6 (NIV)
1 On the first day of the week, very early in the morning, the women took the spices they had prepared and went to the tomb.
2 They found the stone rolled away from the tomb,
3 but when they entered, they did not find the body of the Lord Jesus.
4 While they were wondering about this, suddenly two men in clothes that gleamed like lightning stood beside them.
5 In their fright the women bowed down with their faces to the ground, but the men said to them, "Why do you look for the living among the dead?
6 He is not here; he has risen! Remember how he told you, while he was still with you in Galilee:
