An Alternative Calendar System oops need to factor in leap year...

[bluelanu]

I've created  this script (please excuse my total newb technique) to translate the dates from gregorian dates to this alternative calendar system.

What I did was compare the date with 11.11.11 and then count out from that day to determine what day it is and which cycle(month) it is in relation to that.

This bit I wrote works great - BUT I didn't take into consideration the leap year. and so I have to figure out how to now count leap year days as a copy of the day before it, so if day 21 was the day before the leap year, the leap year day would count as the same and display the same info as day 21, then the following day would continue on to day 22, 23 up to 26 and cycle back to 1 etc..

What I'm hoping is that there's an easy way to factor in the leap year into this script:

 

<?php

$elvenportal = mktime(11,11,11,11,11,2011);
$now = mktime(date("H"),date("i"),date("s"),date("n"),date("j"),date("Y"));
$late = date("H");
$theeday = date("d")-1;
if ($late < 7) {$now = mktime(11,11,11,date("n"),$theeday,date("Y"));}; // timezone correction because of weird server
if ($_POST["dayz"] != "" ){
if ($_POST["month"] != "" ){
if ($_POST["year"] != "" ){
$now = mktime(11,11,11,$_POST["month"],$_POST["dayz"],$_POST["year"]);
};};};

$offset = $now - $elvenportal;
$beyondportal = abs($offset/(60*60*24));


$beyondportal = abs($beyondportal+108);
$day = abs($beyondportal % 26 + 1); //26 days in the cycle.  +1 to make it 1-26 rather than 0-25 
$cycle = abs(intval($beyondportal / 26) % 14+1); //26 days in your cycles.  +1 to make it 1-14 rather than 0-13


if ($elvenportal > $now){
if ($day == 6){$day = 4;}
else if ($day == 7){$day = 3;}
else if ($day == {$day = 2;}
else if ($day == 9){$day = 1;}
else if ($day == 10){$day = 26;}
else if ($day == 11){$day = 25;}
else if ($day == 12){$day = 24;}
else if ($day == 13){$day = 23;}
else if ($day == 14){$day = 22;}
else if ($day == 15){$day = 21;}
else if ($day == 16){$day = 20;}
else if ($day == 17){$day = 19;}
else if ($day == 18){$day = 18;}
else if ($day == 19){$day = 17;}
else if ($day == 20){$day = 16;}
else if ($day == 21){$day = 15;}
else if ($day == 22){$day = 14;}
else if ($day == 23){$day = 13;}
else if ($day == 24){$day = 12;}
else if ($day == 25){$day = 11;}
else if ($day == 26){$day = 10;}
else if ($day == 1){$day = 9;}
else if ($day == 2){$day = 8;}
else if ($day == 3){$day = 7;}
else if ($day == 4){$day = 6;}
else if ($day == 5){$day = 5;}
else if ($day == 6){$day = 4;};

if ($beyondportal > 4){
if ($cycle == 1){$cycle = 8;}
else if ($cycle == 2){$cycle = 7;}
else if ($cycle == 3){$cycle = 6;}
else if ($cycle == 4){$cycle = 5;}
else if ($cycle == 5){$cycle = 4;}
else if ($cycle == 6){$cycle = 3;}
else if ($cycle == 7){$cycle = 2;}
else if ($cycle == {$cycle = 1;}
else if ($cycle == 9){$cycle = 14;}
else if ($cycle == 10){$cycle = 13;}
else if ($cycle == 11){$cycle = 12;}
else if ($cycle == 12){$cycle = 11;}
else if ($cycle == 13){$cycle = 10;}
else if ($cycle == 14){$cycle = 9;};
};


};

Once you get your first IF block set up  so it actually calculates 27-31 for $day, then you need to add a special case where the month is february and the day is 29.
