Converting Gregorian date to Hijri date

Question

How do you convert Gregorian dates to Islamic Hijri dates using JavaScript?

Answer 1

If you need only the year of Hijri date converted from Gregorian date (Miladi date) you can simply write this equation in javascript:

var GregorianYear = (new Date()).getFullYear();
var HijriYear = Math.round((GregorianYear - 622) * (33 / 32));

you can use this simple equation in the footer in master page like كل الحقوق محفوطة لـ ... ©

 م -  هـ

you will get: كل الحقوق محفوطة لـ ... © 2014 م - 1435 هـ

you can also use C# embedded in asp page as:

<%= DateTime.Now.Year %> - <%=  Math.Round((DateTime.Now.Year - 622) * 1.03125) %>

will return : 2014 - 1436

Finally, if you need to convert to UmAlQura date, simply try this line of code:

let _date = new Date('7/10/2019').toLocaleDateString('ar-SA').format('DD/MM/YYYY');

console.log(_date);

will return : ٧‏/١١‏/١٤٤٠ هـ
