Keila, it probably only happens about every 7 years or something. 

Does anyone know how they determine Easter?  That one still baffles me.

So, Paul, where is my "beta" of this?

I really like this skin

KG: easter is the Sunday following the Pascal full moon, which may happen between March 21st to April 18 inclusively. 

Calculating it is another story though, since you must calculate the cycles of the moon.
Here is the algorythm if you're familiar with integer maths:

In the text below, / represents an integer division neglecting the remainder, while % is division keeping only the remainder. So 30/7=4 , and 30%7=2 . 

        a=year%19
        b=year/100
        c=year%100
        d=b/4
        e=b%4
        f=(b+8)/25
        g=(b-f+1)/3
        h=(19*a+b-d-g+15)%30
        i=c/4
        k=c%4
        l=(32+2*e+2*i-h-k)%7
        m=(a+11*h+22*l)/451
        Easter Month h+l-7*m+114)/31  [3=March, 4=April]
        p=(h+l-7*m+114)%31
        Easter Date=p+1     (date in Easter Month)

Note that the above is valid for any year in the past or in the future.
But there is a simpler method, Doggett's modification of Oudin's algorythm, that is valid only for years after 1583. It goes like this :

Again, the divisions are integer divisions, in which remainders are discarded, while the % operator is used to signify the modulo or remainder operator.

century = year/100
G = year % 19
K = (century - 17)/25
I = (century - century/4 - (century - K)/3 + 19*G + 15) % 30
I = I - (I/28)*(1 - (I/28)*(29/(I + 1))*((21 - G)/11))
J = (year + year/4 + I + 2 - century + century/4) % 7
L = I - J
EasterMonth = 3 + (L + 40)/44
EasterDay = L + 28 - 31*(EasterMonth/4)
