Question

I\'m developing a web App and I have a unix timeStamp. I need to convert a unix date format to Jalali/Persian/Shamsi Calendar by using jQuery selectors and then convert it b

Answer 1

I have these simple functions:

function convertTimeStampToJalali(timestamp){
    var date = new Date(timestamp);
    if(!date)
        return false;
    return ( gregorian_to_jalali(date.getFullYear(),(date.getMonth()+1),date.getDate()) );
}//end of function convertTimeStampToJalali

function gregorian_to_jalali(gy,gm,gd){
    g_d_m=[0,31,59,90,120,151,181,212,243,273,304,334];
    if(gy > 1600){
        jy=979;
        gy-=1600;
    }else{
        jy=0;
        gy-=621;
    }
    gy2=(gm > 2)?(gy+1):gy;
    days=(365*gy) +(parseInt((gy2+3)/4)) -(parseInt((gy2+99)/100)) +(parseInt((gy2+399)/400)) -80 +gd +g_d_m[gm-1];
    jy+=33*(parseInt(days/12053)); 
    days%=12053;
    jy+=4*(parseInt(days/1461));
    days%=1461;
    if(days > 365){
        jy+=parseInt((days-1)/365);
        days=(days-1)%365;
    }
    jm=(days < 186)?1+parseInt(days/31):7+parseInt((days-186)/30);
    jd=1+((days < 186)?(days%31):((days-186)%30));
    return [jy,jm,jd];
}//end of function gregorian_to_jalali
