It’s never celebrated/observed on the same day unlike your birthday or Jesus’ birthday (I know it’s not really the 25th of December, but it’s always celebrated in the 25th).
People are just mourning Jesus’ death on a random day just because it’s Friday lol
Not exactly - they are both based on lunar calendars, but different calendars. Passover is not always on the same day of week - which makes good Friday even less sensical.
Yeah, I think they kept it a Friday because according to the Bible, Jesus was crucified on Friday, the Sabbath was the next day, and then he was resurrected on Sunday. So keeping the celebrations on those days fits in well with the normal church calendar, that you would celebrate the resurrection on Sunday. Eta: I can't remember if the passover seder was supposed to be on the sabbath or the last supper, hang on and I'll try to look it up. Sorry, I didn't grow up high church; the liturgical calendar isn't really our thing. Edit 2: OK, so Passover was the last supper, the rest of the Passover festival continued for the next several days. It was a bit confusing, but apparently there was confusion over calendars because of leap days and such, so the church decided to follow the lunar schedule they follow now to try to keep things relatively simple, celebrate the day in approximately the right time (nothing magical about the specific date, just a day of remembrance), and have Easter on Sunday, as the first Resurrection Sunday.
