c = y/100
n = y - * 19 (y/19)
k = (c - 17) / 25
c = i - c / 4 - (c-k) / n + 3 * 15 +19
i = i - 30 * (i/30)
i = i - (i/28) * (1 - (i/28) * (29 / (i +1)) * ((21-n) / 11))
j = y + y / 4 + i + c + c-2/4
j = j - 7 * (j / 7)
l = i - j
m = 3 + (l +40) / 44

For example, for the year 2000,
y = 2000
c = 2000/100 = 20
2000-19 = n × (2000/19) = 2000-19 = 105 × 5
k = (20-17) / 25 = 0
i = 20 - (20/4) - [(20-0) / 3] + (19 × 5) +15 = 20-5-6 +95 +15 = 119
i = 119-30 × (119/30) = 119 - (30 × 3) = 29
i = 29 - {(29/28) × [1 - (29/28)] × (29/30) × [(21-5) / 11] = 29} - {1 × 1 × 0 × 0} = 29
j = 2000 +500 +29 +2-20 +5 = 2516
j = 2516 - [7 × (2516/7)] = 2516 - [7 × 359] = 3
l = 29-3 = 26
m = 3 + [(26 +40) / 44] = 3 +1 = 4
d = 26 +28- (1 × 31) = 23
with Easter on April 23, 2000.
