10 Ways of Referring to Good Friday

1. Friday of preparation
2. Good Friday
3. Holy Friday
4. Mourning Friday
5. Sad Friday
6. Silent Friday
7. High Friday
8. Great Friday
9. Crucified Friday
10. Black Friday (although that has been superseded by the commercial reference to the day after Thanksgiving)

Also, Long Friday, Big Friday, Passion Friday or Easter Friday. The Welsh is dydd gwener y groglith, which I am told means cross reading Friday.
