A Passover on Wednesday is the only day of the week that works with all Biblical accounts of the crucifixion. Yahshua was in the grave "three days and three nights" Matthew 12:40. From Wednesday just before sunset to Saturday just before sunset is three days and three nights. The fact that the day following Yahshua's crucifixion was a Sabbath (Mark 15:42, Luke 23:52-54, & John 19:31) does not prove He was crucified on a Friday. According to the Law of Moses, the day following Passover (which is also the first day of the feast of unleavened bread) is also, always a Sabbath day of rest to be observed like the 7th day weekly Sabbath no matter what day of the week it falls on. (See Leviticus 23:4-8, Numbers 28:16-18, and take special notice of John 19:31 again. The Sabbath immediately following Yahshua's crucifixion was no ordinary Sabbath.)
The link you are in support of, supports what I've been telling you. If you add Saturday night, it would be four nights. Since you don't believe me, believe the site that you advocated. That site also says that Wednesday is the 14th, beginning at sunset on Tuesday.
Go check your own link. It testifies of the truth you have been rejecting. Yah put it in my heart to check the link because I didn't plan on looking at it and you have been exposed by your own sources that you gave me to prove your point. Yahweh ensnares the wicked by the fruit of their own mouth.
Psa 140:9 As for the head of those that compass me about, let the mischief of their own lips cover them.
Psa 9:16 The LORD is known by the judgment which he executeth: the wicked is snared in the work of his own hands. Higgaion. Selah.
Pro 12:13 The wicked is snared by the transgression of his lips: but the just shall come out of trouble.
So if the truth will not do it, I cannot stop you from worshiping idols on pagan Sunday (according to our calendar), which has nothing to do with the resurrection of Yahshua. The Hebrew first day dawns on Saturday evening. What more need I say?
Pro 18:7 A fool's mouth is his destruction, and his lips are the snare of his soul.
