If Easter is really about the resurrection of Jesus then why..........

...isn't it observed 3 days after Passover?

Jesus repeatedly promised that his resurrection would be 3 days after his death.  Here are eleven examples:  Matthew 12:40;16:21;17:23;20:19;27:63; Mark 8:31;10:34; Luke 9:22;18:33;24:7;24:46  (scroll down the page)

This was also pointed out by those after him:  Acts 10:40; 1 Cor 15:4.

There is no quote of Jesus saying anything about being raised on Sunday or the first day of the week.  His focus was always that he would be in the grave for 3 days!

We also know that he was sacrificed at Passover.  See these verses.

Jesus is also referred to as the Lamb and sometimes specifically as the Passover lamb:  See these verses.  (Scroll down)

We see that Jesus is the Passover Lamb, sacrificed on Passover and raised 3 days later.  That is what he wanted us to know.

We know that Passover falls on the 14th day of the first month according to the Creator's luni-solar calendar:

5 The Passover to the Lord comes in the first month, at twilight on the fourteenth day of the month.  (Leviticus 23)

So if Passover is the 14th day of the first month then why isn't the resurrection celebrated on the 17th day of the first month?  Good question!  Sometimes the Passover and Easter are weeks or even a month apart!

From the 3rd paragraph of the Easter entry at wikipedia we find:

The First Council of Nicaea (325) established two rules, independence of the Jewish calendar and worldwide uniformity, which were the only rules for Easter explicitly laid down by the council. No details for the computation were specified; these were worked out in practice, a process that took centuries and generated a number of controversies. It has come to be the first Sunday after the ecclesiastical full moon that occurs on or soonest after 21 March,[11] but calculations vary.

So the date for Easter is independent of the Jewish calendar despite the whole thing being about Passover WHICH IS ON THE JEWISH CALENDAR!

Why is this even important you ask?  Great question!  It's important because Christianity uses the whole Easter Sunday tradition to justify their sin of not practicing the TEN COMMANDMENTS, more specifically the Sabbath commandment:

Remember the Sabbath day, to keep it holy: 9 You are to labor six days and do all your work, 10 but the seventh day is a Sabbath to the Lord your God. You must not do any work—you, your son or daughter, your male or female slave, your livestock, or the foreigner who is within your gates. 11 For the Lord made the heavens and the earth, the sea, and everything in them in six days; then He rested on the seventh day. Therefore the Lordblessed the Sabbath day and declared it holy.  (Exodus 20)

The majority of Christianity ignores the seventh day sabbath in favor of going to church on Sunday (1st day of the Gregorian calendar week).  Yet, Jesus never said anything about this, but instead the sign he gave was 3 DAYS and he died at Passover! 

Why are we celebrating Easter with bunny rabbits and colored eggs?  Both are signs of fertility and are derived from the worship of a fertility goddess named Easter who was worshiped in the Spring!  There are many videos that describe these connections:  Here are some YouTube videos about the pagan origins of Easter.

I beg you the reader to do an in depth study of where all the Easter traditions come from and to reconsider why you are ignoring the Ten Commandments.
