“It was the day of Preparation.
The Sabbath was beginning.”
καὶ ἡμέρα ἦν Παρασκευῆς, καὶ σάββατον ἐπέφωσκεν.
Only Luke uniquely said that it was the day of Preparation (καὶ ἡμέρα ἦν Παρασκευῆς). The Sabbath was beginning (καὶ σάββατον ἐπέφωσκεν) since Sabbath began at sunset. Thus, they hurried to bury him before the sun had set. Do you start you day at sunset?
