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.
Calendar 日历函数
简介
日历扩展是由一系列简单的日历格式转换函数组成。媒介或标准是基于儒略日计数（Julian Day Count）。儒略日计数是从公元前 4713 年 1 月 1 日开始计算的。在不同的日历系统中转换，必须先将其转换为儒略日计数，然后转换为目标日历格式。儒略日计数与罗马儒略历（Julian Calendar）完全不同！更多关于儒略日计数的信息，请访问 » http://www.hermetic.ch/cal_stud/jdn.htm。更多关于日历系统的信息，请访问 » http://www.fourmilab.ch/documents/calendar/。从此页面引用的信息包含了这些介绍，在引号之内。

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,
?>

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 { $amount=-1; }
for ($sh=1;$sh<abs($diff);$sh++){ if ($ppo[4]+$amount>20){

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.
