Hijri.js

A simple implementation for the Islamic calender(Hijri) in Javascript

The Problem

I made this project just because I did not found any correct and open source Hijri converter. Each time I try one its either stored in database and fetch the data each time or it does not give me the correct date "specially when I try before 1420H"

Usage

Current Day

To get Today in Hijri:

<body onload="initWork()" >
    <!-- Include Hijri.js in your work -->
    <script type="text/javascript" src="https://github.com/xsoh/Hijri.js/raw/master/Hijri.js"></script>

    <span>Today is: </span><span id="today"></span>
    <script type="text/javascript">
    function initWork() {
        //Today
        var todayElement = document.getElementById("today");
        todayElement.innerHTML = HijriJS.today().toString();
    }
    </script>
</body>

Conversion

To convert between Hijri and Gregorian use the HijriJS.toHijri(dateString, splitter) to convert Gregorian to Hijri or HijriJS.toGregorian(dateString, splitter) to convert Hijri to Gregorian where the splitter is the symbol splits the date (e.g. for 1434/1/1 is HijriJS.toGregorian("1434/1/1", "/")):

<body>
    <!-- Include Hijri.js in your work -->
    <script type="text/javascript" src="https://github.com/xsoh/Hijri.js/raw/master/Hijri.js"></script>

    <!-- Input Area -->
    <input id="gregorianInput" onchange="convertToHijri()" />
    &nbsp; <span id="hijriDate"></span>

    <script type="text/javascript">
    function convertToHijri() {
        var gregorianDate = document.getElementById("gregorianInput").value
        var hijriDate = document.getElementById("hijriDate");

        var date = HijriJS.toHijri(gregorianDate, "/");
        hijriDate.innerHTML = date.toString();
    }
    </script>
</body>

Formating

More advanced is to print the date with different format you can use date.toFormat(yourStringFormat); where yourStringFormat can be:

YYYY: For the four digit year notation e.g. 1434.
YY: For two year notation e.g. 34 of 1434.
mm: For two digit month notation e.g. 03.
m: For one digit month notation e.g. 3.
dd: For two digit day notation.
d: For one digit day notation.
n: For calender notation "H for Hijri or G for Gregorian".

You can use the same example above and change it like this:


function convertToHijri() {
    var gregorianDate = document.getElementById("gregorianInput").value
    var hijriDate = document.getElementById("hijriDate");

    var date = HijriJS.toHijri(gregorianDate, "/");
    hijriDate.innerHTML = date.toFormat("dd/mm/yyyyN");
}
