''April 12th''? ''the Greek''? Passover was a lunar calendar observance, so it moves around on the Gregorian. It was a mid-month observance of an event on which the Jews packed up and left Egypt in the middle of the night - no street lamps, no LED flashlights, nothing but Jehovah's full moon to light the way. Take a look outside tonight. The Nisan 14 of Moses' day is what's being commemorated; April 12th this year.
''However, early Christians did not hold an annual feast to celebrate a Christianized version of the Jewish Passover. The Abingdon Dictionary of Living Religions states regarding Easter: ''The primitive observance was actually the anniversary (14 Nisan, according to the Jewish lunar calendar) of Jesus' crucifixion.''
The Bible tells us that on the evening before his death, Jesus met with his disciples in a large room to observe the Jewish Passover. (Mark 14:12-16) It was after this, his last Passover, that Jesus instituted what is known as the Lord's Evening Meal. Then he commanded his disciples: ''Keep doing this in remembrance of me.''-Luke 22:19.
This Lord's Evening Meal, which was to be celebrated once a year, was in commemoration of Jesus' death. The apostle Paul said regarding this anniversary: ''As often as you eat this loaf and drink this cup, you keep proclaiming the death of the Lord.''-1 Corinthians 11:25, 26.''

And:
''The name Easter, used in many lands, is not found in the Bible [except as aforementioned]. The book Medieval Holidays and Festivals tells us that ''the holiday is named after the pagan Goddess of the Dawn and of Spring, Eostre.'' And who was this goddess? ''Eostre it was who, according to the legend, opened the portals of Valhalla to receive Baldur, called the White God, because of his purity and also the Sun God, because his brow supplied light to mankind,'' answers The American Book of Days. It adds: ''There is no doubt that the Church in its early days adopted the old pagan customs and gave a Christian meaning to them. As the festival of Eostre was in celebration of the renewal of life in the spring it was easy to make it a celebration of the resurrection from the dead of Jesus, whose gospel they preached.'' ... Nowhere in Scripture do we find mention of these things, nor is there any evidence that the early disciples of Jesus gave them any credence. In fact, the apostle Peter tells us to ''form a longing for the unadulterated milk belonging to the word, that through it [we] may grow to salvation.'' (1 Peter 2:2) So why did the churches of Christendom adopt such obviously pagan symbols into their beliefs and practices?'' Watchtower 4/1/96
Have you noticed how often you have to turn to Jehovah's Witnesses for accurate knowledge (Gk. epignosis) of your own bible? So this is now another topic adequately answered and explained; no need for me to go further.
''and toward them the prophecy of Isaiah is having fulfillment, which says, 'By hearing, YOU will hear but by no means get the sense of it; and, looking, YOU will look but by no means see. 15 For the heart of this people has grown unreceptive, and with their ears they have heard without response, and they have shut their eyes; that they might never see with their eyes and hear with their ears and get the sense of it with their hearts and turn back, and I heal them.'''
