The third day is significant because it is part of the apostolic gospel (1 Cor 15:3-4), it fulfills Scripture (Jonah 1:17 / Matt 12:40; Hos 6:2; Ps 16:10; Isa 53), and it confirms that Jesus is the Messiah, that His atoning death was accepted, that death is defeated, and that believers will be raised (1 Cor 15:17-23). The exact chronology (Friday vs. Thursday) is secondary; the theological point is that God raised Him on the third day according to His promised plan.
