The politest thing to say is nonsense!
The word of Yehova does not yield to man’s false churches, and contortions of the gospels.
The days, beginning with the end of the 4th day when Yeshua was crucified are well explained in the gospels, including the preparation day between the Passover on the 5th day and and the Sabbath.
Yeshua arose at sunset at the end of the regular Sabbath. That is the first day of the week.

That’s why I am saying you are thinking as man thinks and not as God thinks.
Salvation and I don’t always agree but on this she is correct. Jewish reckoning of a day counts even a portion of a day as a day.
5 And entering into the tomb, they saw a young man sitting on the right side, arrayed in a white robe; and they were amazed. ... 3 And they entered in, and found not the body of the Lord Jesus. ... 7 saying that the Son of man must be delivered up into the hands of sinful men, and be crucified, and the third day rise again. From Luke 24.
So it wasn’t a full 72 hours since the angel says...”on the third day rise again”...not “after the third day”!
