Calculating the Date of Easter 336
The God Plays Dice blog has an entertaining post on how the date of Easter is calculated. Wikipedia has all the messy details of course, but the blog makes a good introduction to the topic. "Easter is the date of the first Sunday after the first full moon on or after March 21... [T]he cycle of Easter dates repeat themselves every 5,700,000 years. The cycle of epacts (which encode the date of the full moon) in the Julian calendar repeat every nineteen years. There are two corrections made to the epact, each of which depend[s] only on the century; one repeats (modulo 30, which is what matters) every 120 centuries, the other every 375 centuries, so the [p]air of them repeat every 300,000 years. The days of the week are on a 400-year cycle, which doesn't matter because that's a factor of 300,000. So the Easter cycle has length the least common multiple of 19 and 300,000, which is 5,700,000 [years]."

The date of birth of Jesus was also pulled out of the ass of some Pope. Christian Holidays were set on their particular dates to get medieval folks to stop their 'pagan' rituals and instead celebrate Christian rituals. Christmas:Winter solstice Easter:Beginning of Spring (Ostara now for you Wicans). I'm such a lapsed Catholic I can't remember the Holy days for other celestial events.

Right. Because we have to celebrate everything in exact intervals of one earth-sun-revolution, and only whole-number interval offsets from the time of the original event.
There's no such thing as the 'right' and 'wrong' date. An event happens. Choosing to celebrate that event once a year (where "year" is the amount of time it takes the earth to go around the sun once) is arbitrary in the first place. It would be just as 'right' to celebrate it every 12 moon-earth revolutions, or 2 mercury-sun revolutions.
If you're already going to base your celebration intervals on the convenience of how often one ball of rock revolves around one ball of gas because you happen to live on said ball of rock, you might as well always celebrate something on the 259th day of the year, or the 4th time the 4th day of the week falls in the 11th month of the year, or the 1st 7th day of the week following the vernal equinox.
Getting bent out of shape because the commemoration/celebration of an event doesn't have the same calendar date as the original event - especially when the original event occured in a time period where the calendar you're using didn't even exist - seems pretty silly. Especially when you're celebrating the birth/death of the son of God.

I disagree. Science tells us that, if we don't eat in a certain way, we will die prematurely. It tells us that we must recycle more plastic in order to save the planet. It tells us that the cure for depression is medication. And when we've done all those things (because we'd be stupid, lazy, immoral if we didn't) a whole new lot of science comes along and proves that the opposite is true.
A good scientific education may teach you how to think, but for most people science is something that dictates government policy, legislation, and lifestyle choices without their actually having to understand any of the details or processes. For most people, science becomes a faith. I'd bet that the average American or Briton does more things based on the latest scientific evidence than s/he does based on religious belief.

The story of Jesus is complicated, especially so when you bring the trinity into it. But the connections to passover would lose it's significance when for the most part passover is still practiced widely. As it is, the rituals and celebrations would become a droned out day with little or no meaning without the connection.

I'm tired of having to go over this with my atheist friends.
Please. Remember this, if you remember nothing else.
The term "Zombie Jesus" makes no sense.
The religious belief is that Jesus "came back from the dead", or "rose from the dead". The angel said "Why seek ye the living among the dead?".
Zombies, on the other hand, are not living OR dead. They are the undead, which is a different thing entirely.
You would think since atheists believe both are make believe, they would be able to distinguish among the two.
Then again maybe the real issue is that most of them don't understand the belief, so most of their comments sound like retardedness to those of us who do believe.
Case in point: The last time I explained this to an atheist, their response was "Well why didn't he just come back again the 2nd time he died?"
Really? If you are ignorant enough to be able to make that comment, you are too ignorant to argue against that establishment of religion.

The date of Christ's death is fixed on the Jewish calendar. There are other comments giving possible actual dates listed here. I personally subscribe to the 15 Nisan 31 CE date (putting the crucifixion on a Wednesday), but I don't have problems with people who prefer 14 Nisan on a different year. Passover always starts with a day of preparation on 14 Nisan, each and every year, followed by the seven day passover feast. If you go through the chronology of the Bible, you'll then come up with a crucifixion on either the day of preparation or Passover itself. This is followed by three days in the grave and a Resurrection on the Jewish first day of the week (any time Saturday sunset to Sunday morning when the tomb was seen to be empty).
The whole problem is that the Jewish calendar doesn't match up with ours. Its months are based on the lunar cycles and tend to have fixed lengths. In order to keep in sync with the Earth's rotation around the sun, leap days are added as needed and every few years a leap month is added. These are always added at the end of the year. Thus, 15 (or 14) Nisan is always a fixed date on the Jewish calendar since it's in the first month of the year, but it won't match to a fixed date on the Gregorian calendar. Likewise, the day of the Resurrection (three days after His crucifixion) will not always come on a Sunday since Passover moves w.r.t. the Gregorian calendar, which irritated a Bishop back in the early hundreds, and caused the goofy Easter mess in the first place. If you want a modern day parallel, look up Golda Meir's date of death. If you were to commemorate this as a Jew, you'd almost certainly do it on the same date on the Jewish calendar each year. Yet this moves the date on the Gregorian calendar around the same way Passover moves. Last year, it (8 Kislev) would have been November 18 Gregorian. Next year it will be December 5. The year after, it'll be back in November.
If you're really interested, you should study what the passover was about (instituted long, long before Christ was born), and look at how perfectly it was a type of Christ's death. It's really fantastic. Even the actual Jewish passover rituals are a type of Christ's death, burial, and resurrection. It's a shame not many Jews have really seen that yet. The next passover, when He returns for His church in the air will be just as great an event. We don't know when that will be, but many of the Christian "big events" (Christ's birth, Christ's death, the initial outpouring of the Holy Spirit) have occurred at the times of established Jewish festivals.
I tend to agree that we should celebrate Christ all the time and not just on one day, but I'd like to see it move to be in sync with passover, regardless of whether that happened to put it on a Sunday or not on the Gregorian calendar. They ought to get Maundy Thursday and Good Friday corrected while they're at it.
And yes, the December 25th birth date is just as goofy - both for reasons of a fixed Jewish calendar date never being fixed on the Gregorian calendar, and for it needing to be tied to the Feast of Tabernacles which is much earlier in the year (15 Tishri). A good bet for a birth date would be October 4, BC 4 (Tishri 15, 3757) according to some sources.
Getting bogged down in debates over dates obscures the most important facts. He was crucified to provide a holy sacrifice for our sin. He bore stripes for our healing. Roman guards were posted to guard the tomb under penalty of death if anything happened to the body. They didn't count on angels showing up and rolling away the covering rock (not that Christ needed angels help - that was for the benefit of the people who would come). He arose, just as He said He would after three days. He arose with keys to the death and the grave, and led those righteous souls who were being kept under Satan's control in the grave to heaven. He appeared bodily to hundreds after that point in time (and at the time of His resurrection, many others who had died were also seen in Jerusalem before going to Heaven). He is reigning on the right hand of God. At some point, God will send Him to gather up His church. You don't want to miss that time.
