why is good friday called good friday?

[SpikesGirl]

My dd who is 10 wants to know. Have read is other name for holy. She says isn't good as Jesus died and that's not good. Sorry if silly question.

I have been told two things

1 its a corruption from God Friday

2 its good because Jesus had to die to come back to life again to save us all

take your pick

The etymology of the term "good" in the context of Good Friday is contested. Some sources claim it is from the senses pious, holy of the word "good"[10], while others contend that it is a corruption of "God Friday"[11].
