I'm creating a calendar script for our intranet, built basically off a series of included files.

<?php include ('global/inc/calendar'.date("m").'.inc.php\'); ?>


<?php

$firstday = date("w", mktime(0,0,0,date("n"), 1, date("Y")));
$holidays = array();

// New Year's Day
if (date("w", mktime(0,0,0, 1, 1, date("Y"))) == 0) {
    // if NYD is a Sunday
    $holidays[2] = "New Year's Day Public Holiday";
} elseif (date("w", mktime(0,0,0, 1, 1, date("Y"))) == 6) {
    // if it's a Sat
    $holidays[3] = "New Year's Day Public Holiday";
} else {
    // any other day
    $holidays[1] = "New Year's Day";
}

// Australia Day
if (date("w", mktime(0,0,0, 1, 26, date("Y"))) == 0) {
    // if the 26th is a Sunday.
    $holidays[27] = "Anzac Day Public Holiday";
} elseif (date("w", mktime(0,0,0, 1, 26, date("Y"))) == 6) {
    // if it's a Sat
    $holidays[28] = "Anzac Day Public Holiday";
} else {
    // any other day
    $holidays[26] = "Anzac Day";
}

print ("    <table style=\"width: 100%;\">
        <tbody>");
// find the day on which the first day of the month falls
switch ($firstday) {
    case "0":
        // the first is a Sunday
        print ("<tr>\n");
        break;
    case "1":
        // the first is a Monday
        print ("<tr>\n<td>&nbsp;</td>\n");

        print ("<tr>\n<td>&nbsp;</td>\n<td>&nbsp;</td>\n");
        break;

        break;
}
for ($d = 1; $d <= date("t"); $d++) {
    // for all the days in a month, print a cell in the table
    $style = " style=\"";
    if (array_key_exists($d, $holidays)) {
        $style .= "font-weight: 700; color: #CC0000;";
    }
    if ($d == date("j")) {
        $style .= "background-color: #FFFFFF;";
    }
    $style .= "\"";
    if (date("w", mktime(0,0,0,date("n"), $d, date("Y"))) == 0) {

    </table>");

print ("<p style=\"font-weight: 700;\">Holidays this Month</p>\n

    <tbody>");
foreach ($holidays as $key => $value) {

I can handle almost every holiday in this fashion, except, of course, easter?

Any clues? Or am I best off defining in a static file the dates of easter for the next 10 years or so, and then including that file?

EDIT: solved, using easter_date()
