When was Jesus crucified?

I believe most scholars still put it on friday. There's no mention of a special sabbath anywhere near the crucifix accounts.
The problem that if friday is true, then Jesus wasn't in the grave 3 days and 3 nights is usually countered by the fact that Jews counted the first day as the same day.
It is huge complicated stuff as found;
Friday crucifixion three days and three nights Nisan 14 sign of Jonah
but they reckon that 3 days in a Jewish account would mean in our thinking three days and 3 nights.
So, when Luke said 3 days and 3 nights, he meant 3 days as the Jews meant.
Ooops, did you want to know all this I find the argument weak actually.Lucy
