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
I could be wrong but iirc it is scheduled off of a lunar calandar that doesn't conform perfectly to your solar one. It relates that lunar calandar to the spring equinox, which determines Easter, which determines Good Friday.
Well why not have it on a consistent moon cycle then, like, the full moon of April, rather than on specifically a weekend (calculated based on solar calendar)
It moves because Passover moves
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.
For fun
How do modern Christians justify it not being related to the Bible?
I imagine there is some (probably thin) after-the-fact biblical interpretation that justifies scheduling it like that, and all the order of days and such is more closely related to the bible, so its just the placement that sticks out. But I think it's because after the bible was written, the authority for determining questions like that was passed to the church directly by Christ. As the one true church, they then could faithfully determine ambiguous things as would be willed by God. So they worked it out as God willed it more or less. But also I don't think the date itself is really considered special, nor is Christmas, it's the things you do on the days that lend it meaning. There is no ritual significance to the equinoxes (def a symbolic one though), no spell you have to cast under the correct celestial configuration to ensure anything, the ritual significance is the Mass and all of that jazz, and that's just the time they picked to do that stuff cause everyone must do it at the same time
