Easter_date

V jednom skripte, ktory som stiahol z netu je pouzity Easter_date a tu na WZ to nie je povolene. Da sa to nejako vyriesit?
Staci se podivat do online manualu. Je tam alternativni funkce:

<?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;

}
?>
Dík, skusim to.
