That Christ had risen was apparently discovered very early on sunday but the discovery was not his resurrection.
His crucifixion began on wednesday afternoon, just before the sacrifice for passover, which was at sundown, wednesday.
It was a perfect three nights and days that he lay in the tomb.
He rose on the YHvH commanded Feast Day of First Fruits. Paul refers to Yah'shua as our "First Fruits" in Corinthians. Yah'shua did not rise on "Sunday".

The Feast Day is known as Yom HaBikkurim
It is the day following the Shabbat following Passover.
See Leviticus 23
