note 21562 modified in function.easter-date by aidan

A much smaller hack is the following. I ported this from a Delphi implementation of a function calculating easter dates. <?php function easter_date ($Year) { /* G is the Golden Number-1 H is 23-Epact (modulo 30) I is the number of days from 21 March to the Paschal full moon J is the weekday for the Paschal full moon (0=Sunday, 1=Monday, etc.) L is the number of days from 21 March to the Sunday on or before the Paschal full moon (a number between -6 and 28) */ $G = $Year % 19; $C = (int)($Year / 100); $H = (int)($C - ($C / 4) - ((8*$C+13) / 25) + 19*$G + 15) % 30; $I = (int)$H - (int)($H / 28)*(1 - (int)($H / 28)*(int)(29 / ($H + 1))*((int)(21 - $G) / 11)); $J = ($Year + (int)($Year/4) + $I + 2 - $C + (int)($C/4)) % 7; $L = $I - $J; $m = 3 + (int)(($L + 40) / 44); $d = $L + 28 - 31 * ((int)($m / 4)); $y = $Year; $E = mktime(0,0,0, $m, $d, $y); return $E; } ?> --was-- A much smaller hack is the following.
