I thought you may enjoy this information, gg: According to scripture, Christ was delivered up two days before the passover that year. The passover was celebrated on the 14th day of the month of Nisan, of the ancient Hebrew calendar. That calendar was based on lunar months, and so does not correlate with our monthly calendars. The 14th day of Nisan does not fall on the same day of the week from year to year, much like a birthday or anniversary falls on different days of the week as years go by. That means that the day of the week that the anniversary of Christ's death occurs on changes every year. It's not necessarily Friday. Further, nowadays the timing of the holiday is in it's relation to Easter, and the determination of when Easter is celebrated has more to do with when the first sunday after the vernal equinox occurs, rather than on its relationship to passover. That's why there are years that passover and easter are not celebrated very simultaneously. There is no evidence that early christians observed any easter festivals. There is also no mention of the holiday by early church fathers (the catholic church did not exist until the time of emperor Constantine, some 200 years after Christ). This above, according to the Encyclopedia Britannica. The Catholic Encyclopedia states that the early church fathers knew nothing of any easter festival. In fact, the mention of "easter" in the King James version (Acts 12:4) is a mistranslation of the greek word "paska", which actually meant "passover", but the translators were influenced to render it thus, and in some other versions, you will read the word "passover" instead (according to the Westminster Dictionary of the Bible). Easter itself was originally a spring festival celebrated around the vernal equinox in honor of the teutonic Anglo-Saxon goddess of light and fertility, "Eastre", which is where the holiday gets it's name. Funny, isn't it, that a holiday about the proclaimed 'son of the one true God' has a holiday named after a pagan goddess? Anyway, around the 8th century (some 800 years after Christ), the name was transferred to the christian festival. It's no wonder other fertility symbols, such as eggs and bunny rabbits, are still associated with the holiday (Standard Dictionary of Folklore). In fact, as per the link you supplied, a further link into that site confirms the above in parts: http://www.newadvent.org/cathen/05224d.htm
