Summary
A) Day and Month
1) Deuteronomy mentions no dates;
2) Exodus dates all aspects of ‘the passover’, on Abib 14;
3) a: Leviticus and all the other ‘Law’, date passover-sacrifice:-
sacrificed and ‘killed’, in the day that leaven was removed on:- Abib 14; while
b: Leviticus and all the other ‘Law’, date passover-sacrifice:-
eaten and ‘feasted’, in the night after— on Abib 15.
B) “The passover” was eaten
1) while being roasted and
2) together with the first of unleavened bread being eaten;
3) in the night of Nisan 15,
4) on the passover’s own ‘sabbath day’ after Nisan 14
5a) on the ‘sabbath’ associated with passover’s feasting (Jn19:31, Lv23:11,15,16);
5b) on the ‘sabbath’ determined according to the determination of the solar year; and
5c) not “The Sabbath according to the (Fourth) Commandment”.
Conclusion
“The day after the (passover’s) sabbath”, and day of First Sheaf Wave Offering Before the LORD, Nisan 16, in the year of our Lord’s death and resurrection, fell on the weekly Sabbath, and not on the First Day of the week or ‘Sunday’.
Accepted given
1) Exodus dates both sacrifice of passover and meal of passover-sacrifice, “without leaven”, on Nisan 14;
2) All the rest of the Law dates passover-sacrifice sacrificed, on Nisan 14, and passover-sacrifice eaten, on Nisan 15;
3) The acknowledged difference between Exodus and the later Law being of prophetic significance showing how in the end-time the Passover Lamb of God and of us would become Sacrifice Sacrificed, and, Sacrifice Eaten, on Nisan 14, so that all the Scriptures concerning Him might be fulfilled.

Here is where the Christ of God began entrance into the Kingdom of God in His Suffering and Glory of the Father.
Matthew Henry
‘Commentary’,
In this chapter (Lv23) we have the institution of holy times. 1. The weekly feast of the sabbath ver. 3. 2. The yearly feasts, 1. The passover, the feast of unleavened bread (ver.4-8), to which was annexed the offering of the sheaf of firstfruits, ver. 9-14. 2. Pentecost, ver. 15-22. ....
Verses 1-3
Here is, 1. A general account of the holy times which God appointed (v. 2).... Concerning the holy times here ordained, observe, 1. They are called ‘feasts’.... 2. They are the feasts of the Lord (‘my feasts’). 3. They were proclaimed.... 4. They were to be sanctified....
2. A repetition of the law of the sabbath in the first place.... v. 3....
Verses 4-14
Here again the feasts are called the ‘feasts of the Lord’, because He appointed them....
1. A repetition of the law of the passover, which was to be observed on the fourteenth day of the first month....
2. An order for the offering of a sheaf of the first-fruits, upon the second day of the feast of unleavened bread; the first (day of the feast of unleavened bread) is called the ‘sabbath’, because it was observed as a sabbath (v. 11), and, on the morrow after, they had this solemnity.... a sheaf.... was brought to the priest who was to heave it up.... We find that when they came into Canaan the manna ceased upon the very day that the sheaf of first-fruits was offered; they had eaten of the old corn the day before (Josh.5:11), and then on this day they offered the first-fruits (sheaf). ‘Commentary’
Alexander Cruden,
‘Concordance’, ‘passover’,
The feast (of passover) was kept.... from the 14th to the 21st Nisan.... As the beginning of the month was dependent on the moon there was nearly a month’s difference between the possible times of (its) beginning. This is the reason for the varying dates of our Easter....
There were many rules as to the Passover Supper, some given in Exodus being for the first celebration only.
Actually the beginning of the “first of the months for you”, ‘Abib’, was dependent on the turn of the year with winter solstice, which was determined – it is not stated in the Bible – astrometrically. The day after winter solstice on which between sunset and sunset the new moon occurred (regardless of its visibility), was determined the first day of the First Month (Abib or Nisan). It could occur on any day of the week, naturally. As a result the fourteenth day of the month would also have occurred on any day of the week. Its date simply had nothing to do with the weeks’ cycle. It meant the passover’s “sabbath day” in Lv23:11,15,16, could fall on any ‘week-day’, and occasionally might have coincided with the weekly Sabbath Day.
This has been the universally accepted viewpoint in both Christianity and Judaism until only about a century ago certain ill-informed decided the word ‘sabbath’ in Leviticus 23 refers to the Seventh Day Sabbath. These people relied on documents of the Pharisees who – long after Christ – in their documents disputed the Sadducees’ viewpoint who – allegedly, according to the Pharisees – argued the word ‘sabbath’ in Leviticus 23 referred to the Seventh Day Sabbath. There never existed a source originally the Sadducees’ with this claim. Regardless, the enthusiasts took hold of the Sadducees’ second hand theory to build a case for Sunday-worship on the presumption of a coincidence of Sunday and the Resurrection and Pentecost / First Sheaf Wave Offering and First Loaves Wave Offering.
Needless to say, their theory has been nothing but conjecture and groundless speculation, refuted by every fact of Scripture, science and Christian and Judaic tradition.
This then established, that “the sabbath” and “the day after the sabbath” in Lv23:11,15,16 could have occurred on any week-day, it is established both First Sheaf Wave Offering and First Loaves Wave Offering, in the old dispensation or ministration, occurred on any week-day— the fact of which forces one to completely rely on the information given in the Gospels, to determine on which day of the week First Sheaf Wave Offering and First Loaves Wave Offering in the year of the death and resurrection of Jesus, indeed occurred. Which to find out and illustrate, I have been doing for many years, as far as I could see, from anybody’s every possible angle of approach— besides, having tried to show how the Sabbath Day promised in the end to be just the day upon which Christ would rise from the dead.
