Adhan JavaScript

The Adhan JavaScript implementation is written to be compatible with the latest version of all major browsers.

Build Status



Simply include Adhan.js in your HTML page

<script src="Adhan.js"></script>


Adhan is available in npm

npm install adhan

and then require the module

var adhan = require('adhan')

Upgrading from 1.0.1 to 2.0.0

Upgrading to 2.0.0 introduces breaking API changes.

JavaScript Date and Number prototypes are no longer patched by this library. The library should now be pure without any side effects.

This means you can no longer depend on methods like formattedTime being directly accessible on the Date instance. For example,


prayerTimes.fajr.formattedTime(); // no longer works


adhan.Date.formattedTime(prayerTimes.fajr); // works


To get prayer times initialize a new PrayerTimes object passing in coordinates, date, and calculation parameters.

var prayerTimes = new adhan.PrayerTimes(coordinates, date, params);

Initialization parameters


Create a Coordinates object with the latitude and longitude for the location you want prayer times for.

var coordinates = new adhan.Coordinates(35.78056, -78.6389);


The date parameter passed in should be an instance of the JavaScript Date object. The year, month, and day values need to be populated. All other values will be ignored. The year, month and day values should be for the local date that you want prayer times for. These date values are expected to be for the Gregorian calendar.

var date = new Date();
var date = new Date(2015, 11, 1);

Calculation parameters

The rest of the needed information is contained within the CalculationParameters object. Instead of manually initializing this object it is recommended to use one of the pre-populated instances in the CalculationMethod object. You can then further customize the calculation parameters if needed.

var params = adhan.CalculationMethod.MuslimWorldLeague();
params.madhab = adhan.Madhab.Hanafi;
params.adjustments.fajr = 2;
Parameter Description
method CalculationMethod name
fajrAngle Angle of the sun used to calculate Fajr
ishaAngle Angle of the sun used to calculate Isha
ishaInterval Minutes after Maghrib (if set, the time for Isha will be Maghrib plus ishaInterval)
madhab Value from the Madhab object, used to calculate Asr
highLatitudeRule Value from the HighLatitudeRule object, used to set a minimum time for Fajr and a max time for Isha
adjustments JavaScript object with custom prayer time adjustments in minutes for each prayer time


Value Description
MuslimWorldLeague Muslim World League. Fajr angle: 18, Isha angle: 17
Egyptian Egyptian General Authority of Survey. Fajr angle: 19.5, Isha angle: 17.5
Karachi University of Islamic Sciences, Karachi. Fajr angle: 18, Isha angle: 18
UmmAlQura Umm al-Qura University, Makkah. Fajr angle: 18, Isha interval: 90. Note: you should add a +30 minute custom adjustment for Isha during Ramadan.
Dubai Method used in UAE. Fajr angle: 18.2, Isha angle: 18.2.
Qatar Modified version of Umm al-Qura used in Qatar. Fajr angle: 18, Isha interval: 90.
Kuwait Method used by the country of Kuwait. Fajr angle: 18, Isha angle: 17.5
MoonsightingCommittee Moonsighting Committee. Fajr angle: 18, Isha angle: 18. Also uses seasonal adjustment values.
NorthAmerica Referred to as the ISNA method. This method is included for completeness but is not recommended. Fajr angle: 15, Isha angle: 15
Other Fajr angle: 0, Isha angle: 0. This is the default value for method when initializing a CalculationParameters object.


Value Description
Shafi Earlier Asr time
Hanafi Later Asr time


Value Description
MiddleOfTheNight Fajr will never be earlier than the middle of the night and Isha will never be later than the middle of the night
SeventhOfTheNight Fajr will never be earlier than the beginning of the last seventh of the night and Isha will never be later than the end of the first seventh of the night
TwilightAngle Similar to SeventhOfTheNight, but instead of 1/7, the fraction of the night used is fajrAngle/60 and ishaAngle/60

Prayer Times

Once the PrayerTimes object has been initialized it will contain values for all five prayer times and the time for sunrise. The prayer times will be Date object instances initialized with UTC values. To display these times for the local timezone, a formatting and timezone conversion extension to the Date object has been provided. Call formattedTime(date) and pass in the date instance and the UTC offset in hours for the appropriate timezone. There is also a second optional parameter of style, if you pass in '24h' the times will be formatted in 24 hour mode.

adhan.Date.formattedTime(prayerTimes.fajr, -4);
adhan.Date.formattedTime(prayerTimes.fajr, -4, '24h');

Full Example

var date = new Date();
var coordinates = new adhan.Coordinates(35.78056, -78.6389);
var params = adhan.CalculationMethod.MuslimWorldLeague();
params.madhab = adhan.Madhab.Hanafi;
var prayerTimes = new adhan.PrayerTimes(coordinates, date, params);
var formattedTime = adhan.Date.formattedTime;
document.write('Fajr: ' + formattedTime(prayerTimes.fajr, -4) + '\n');
document.write('Sunrise: ' + formattedTime(prayerTimes.sunrise, -4) + '\n');
document.write('Dhuhr: ' + formattedTime(prayerTimes.dhuhr, -4) + '\n');
document.write('Asr: ' + formattedTime(prayerTimes.asr, -4) + '\n');
document.write('Maghrib: ' + formattedTime(prayerTimes.maghrib, -4) + '\n');
document.write('Isha: ' + formattedTime(prayerTimes.isha, -4) + '\n');


Adhan is made publicly available to provide a well tested and well documented library for Islamic prayer times to all developers. We accept feature contributions provided that they are properly documented and include the appropriate unit tests. We are also looking for contributions in the form of unit tests of of prayer times for different locations, we do ask that the source of the comparison values be properly documented.
