Now after the Sabbath, toward the dawn of the first day of the week, Mary Magdalene and the other Mary went to see the tomb.
Matthew 28:1

They had to wait until after the weekly Sabbath was ended because they needed to buy some spices for anointing Yeshua's body. There is a brief period of light between sunset on the seventh day and the full dark of the first day, but "toward the dawn" indicates a rising sun, not a setting one. They probably purchased those spices in the twilight after the Sabbath, but then had to wait until the sun began to rise before going to the tomb.

By the way.... Shabbat shalom!
