One has to go by the Jewish lunar calendar. The Jewish day starts at sunset or 6:00 pm our time. So technically Jesus could have risen any time after 6 pm on Saturday.
There are rest days or sabbaths during the Passover week etc. It just happens to be Wednesday when HE was crucified and Sunday when he rose. on the 3rd day
Simple “Biblical” math:
Thursday (Sabbath feast of Unleavened Bread): evening & morning day 1
Friday: evening & morning day 2
Shabbat: evening & morning day 3
And so He rose as “Lord of the Sabbath” on the Sabbath
Mat 28:1 In the end (G3796) of the Sabbath, as it began to dawn (G2020) toward the first day of the week, came Mary Magdalene and the other Mary to see the sepulchre.
G3796 ‘opse’ From the same as G3694 (through the idea of backwardness); (adverbially) late in the day; by extension after the close of the day: - (at) even, in the end.
G2020 'epiphosko' A form of G2017; to begin to grow light: - begin to dawn, draw on
"as the first of the week drew near"
One can not be going towards something is they are already in it, while also keeping in mind the Appointed Times of the Messiah, this verse, therefore, is more properly be translated as, "as the first of the counting of the weeks drew near", as in relation to the counting of the 7 weeks leading up to Pentecost (Feast of Weeks).
In the beginning the “Light” was surrounded by darkness (Jesus in the tomb) and then the “Light” was called to come forth out of the darkness (resurrection from the tomb), and there was evening and morning the first day.
Shalom & may your Festival week of Unleavened Bread be blessed, ours begins Friday at sunset as the full moon rises shortly after 7pm.
