# Easter date function in hhvm

I noticed that hhvm does not support the easter_date () function.

http://docs.hhvm.com/manual/en/function.easter-date.php

Is there an alternative for this? I need to use this function or equivalent and I want to use HHVM as well.

thank

You can implement the function algorithm `easter_date`

:

```
if (!function_exists('easter_date')) {
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 - (int)($C / 4) - (int)((8*$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;
}
}
```
