When I first ran this routine, I was referencing $month not $months, and for some reason it was still returning the month but not the cause, but the variable didn't exist. I found this odd around this time. I didn't know what would cause my RSS Feed to display the month even when there was no variable referred to the data.
달력 함수
소개
이 달력(calendar) 확장은 서로 다른 달력 형태를 변환시켜 주는 함수들을 제공한다. 율리우스 날짜수(Julian Day Count)에 기반하여 변환이 된다. 율리우스 날짜수은 율리우스 1세, 4713 B.C. 부터 지난 날짜수가 된다. 달력 시스템 사이의 변환을 위해서는, 먼저 율리우스 날짜수으로 변환해야 하고, 그 다음에 원하는 달력 시스템으로 변환하는것이다. 율리우스 날짜수는 율리우스력(Julian Calendar)와는 매우 다른것이다! 율리우스 날짜수(Julian Day Count)에 대해 더 많은 정보를 얻고 싶으면 » http://www.hermetic.ch/cal_stud/jdn.htm를 방문한다. 날짜 시스템에 관한 더 많은 정보를 원하면 » http://www.fourmilab.ch/documents/calendar/를 방문한다. 이 설명서중에서는 위의 페이지에서 발취한 내용을 ""로 둘러 싸고 있다.
설치
이 함수들를 작동시키기 위해서는, PHP를 컴파일할때 --enable-calendar 옵션을 써야 한다.
PHP 윈도우 버전에서는 이 확장에 대한 지원이 포함되어 있습니다. 이 함수들을 이용하기 위해서 추가로 확장을 읽어들일 필요가 없습니다.
실행시 설정
이 확장은 php.ini 설정이 존재하지 않습니다.
자원형
이 확장은 리소스형을 정의하지 않습니다.
예약 상수
이 확장은 다음의 상수들을 정의합니다. 이 확장을 PHP에 내장했거나, 실행시에 동적으로 읽어들일 경우에만 사용할 수 있습니다.

This section of code need to be changed in the calculation I noticed today in our RounCalendar we had a zero day this function will calculate the month and day correctly for the calendars, it is a pretty universe piece of code, I am sorry it wasn't properly tested and need some refactoring.

This is the egyptian calendar which was the first 365 day calendar on the planet it has no leap year which makes it a little inaccurate but you can work on your own implementation of this code when you like, this is another implementation of the roun floating point code which is a universal code for generating date codec's you can make practically all calendars with this code the $pweight is based on my research on carbon date stamping etc of when egypt epoch or PPO was made, some people argue a few thousand years while other can date egypts epoch being around 30000 years ago!! This is on the basis of tidal marking on statues and momuments when the are was covered in water after construction from sea level rising.

btw in my previous post of the Mayan Tikal calendar the top part of the function was chopped off in my code cut and paste that is the line for the function which looks like, the top 3 line will need to be replace with:
<?php
print_r(MayanTikalCalendar(time(),0));
function MayanTikalCalendar($unix_time, $gmt,
?>

Well this is the second part, well more the second calendar of Maya the Tikal there is two of them one for long count, one for general date seeding, this is using an implementation of floating point time (roun).

This will return the mayan long count calendar which cycle reaches 13.0.0.0.0 in 2012, I have had to compress the changemaya function for this code library so if you want to space it out your more than welcome. It works with unix time. To call the routine use the following syntax. The mayan calendar is a day count that is around 5000 years old, it tracks our cestial position in the galaxy
<?php
echo MayanLongCount(time());
function MayanLongCount($tme){
$config = array('ppo' => array(13,0,0,0,0),
'epoch' => strtotime('2012-12-21'));
$diff=(($tme-$config['epoch'])/(60*60*24));
$ppo = changemaya($config['ppo'],ceil($diff));
return $ppo[0].'.'.$ppo[1].'.'.$ppo[2].'.'.$ppo[3].'.'.$ppo[4];
}
function changemaya($ppo,$diff){
if ($diff>0) { $amount=1; } else { $amount=-1; }

To calculate NTP timestamp from unix timestamp:
<?
function ntptime()
{
return 2208988800 + time();
}
?>
NTP timestamps are represented as a 64-bit unsigned fixed-
point number, in seconds relative to 0h on 1 January 1900.

fRay Fergusons light reimplimentation doesn't work all of the time, because of the inaccuracy in the calculations (it is quite accurate but not accurate enough for a live web app)
