why is good friday called good friday

Good Friday is called "Good" Friday because it marks the day Christians believe Jesus Christ willingly suffered and died by crucifixion as the ultimate sacrifice for humanity's sins, which brought about salvation and the possibility of eternal life. The term "good" in this context is understood as "holy" or reflecting the goodness of the event's outcome—Jesus' death conquered sin and death, offering redemption to all people. While the day commemorates a sorrowful and painful event, it is called "good" because it represents the triumph of good over evil and God's plan to save humanity through Jesus' sacrifice. Some also suggest the name evolved from "God's Friday" or is related to the use of "good" to mean holy, as in "Good Tide" for Christmas.
