Nice work but some problems.

1. "甲寅(虎)年 三月十九" this is showing after the birthdatefield in the profile page.

2. "Edit profile items" link in admin menu is gone.

3. most of the variables are in chinese in the lib.php file. For example

function cyclical($num) {
            $Gan = Array ("甲", "乙", "丙", "丁", "戊", "己", "庚", "辛", "壬", "癸" );
            $Zhi = Array ("子(鼠)", "丑(牛)", "寅(虎)", "卯(兔)", "辰(龙)", "巳(蛇)", "午(马)", "未(羊)", "申(猴)", "酉(鸡)", "戌(狗)", "亥(猪)" );
            return $Gan [$num % 10] . $Zhi [$num % 12];
        }
   
        function display() {
            $nStr = array ('   ', '正', '二', '三', '四', '五', '六', '七', '八', '九', '十', '十一', '腊' );
            $nl = sprintf ( "%s年\n%s%s月%s\n", $this->cyclical ( $this->yearCyl ), ($this->isLeap ? " 闰" : ""), $nStr [$this->month], $this->cDay ( $this->day ) );
            //echo   sprintf("农历   %s%s月%s<br>",($this->isLeap?" 闰":""),$nStr[$this->month],$this->cDay($this->day)); 
            //echo   sprintf("%s年   %s月   %s 日",$this->cyclical($this->yearCyl),$this->cyclical($this->monCyl),$this->cyclical($this->dayCyl)); 
            RETURN $nl;
        }
   
        function cDay($d) {
            $nStr1 = array ('日', '一', '二', '三', '四', '五', '六', '七', '八', '九', '十' );
            $nStr2 = array ('初', '十', '廿', '卅', '　' );
           
            switch ($d) {
                case 10 :
                    $s = '初十';
                    break;
                case 20 :
                    $s = '二十';
                    break;
                case 30 :
                    $s = '三十';
                    break;
                default :
                    $s = $nStr2 [floor ( $d / 10 )];
                    $s .= $nStr1 [$d % 10];
            }
            return $s;
        }
    }

Should be in english for users to know what they are doing.

And a feature request to show birthdates in " 14th Feb 1978" this format would be great and separate access controls for year and rest of the birthdate(day and moth) So that we can just show "14th February " to public.

Thanks for the great work anyway.

"甲寅(虎)年 三月十九" is your birthday in Chinese Lunar calendar }:)

I'll add comments to the class Lunar.This class was write by somebody else.

Year show toggle will add later,I'm hard to get time to do this for now.

And,I disabled profile item edit from admin page.

As the customized profile item doesn't use '$shortname' for metadata name,that makes this problem:U setup a customize profile item name 'website',but it dosen't show the meta named 'website' that user saved before u do the customize.

thanks Snow...very great work!

I'm agree with bosssumon :

a better graphic in edit profile

and more clear code for all....

then i hope elggteam take this work as default for elgg.

thanks again!

About graphic edit profile.Er...I not going to do that as codes is more friendly than to GUI for my self }:P

About the codes in Chinese.All the Chinese char is just for Chinese Lunar birthday output.
