Welcome to Pray Times, an Islamic project aimed at providing an open-source library for calculating Muslim prayers times.

General Usage

The first step for using PrayTimes in a web-page or widget is to include it using a line like this:

<script type="text/javascript" src="PrayTimes.js"></script>

After including PrayTimes.js, an object named prayTimes is created and is ready to use. We can immediately get the prayer times (using the default settings) from this object. For example, to get today's prayer times for a location with latitude 43, longitude -80, and time zone -5, we can call:

prayTimes.getTimes(new Date(), [43, -80], -5); There are several functions for adjusting calculation parameters. For example, we can call the following function (before calling getTimes) to change the calculation method to ISNA:

prayTimes.setMethod('ISNA'); Details of the functions available in PrayTimes along with their description are provided below.

Get Prayer Times

The following function is used to retrieve prayer times for a given date and location:

getTimes (date, coordinates, timezone, dst, format) The input parameters are described below:

date The date for which prayer times are calculated. You can use new Date() to specify today. Date can be also entered as a triple [year, month, day]. For example, [2009, 2, 26] specifies February 26, 2009. coordinates Specifies the coordinates of the input location as a triple [latitude, longitude, elevation]. Latitude is a real number between -90 and 90, longitude is between -180 and 180, and elevation is a positive number, specifying the height in meters with respect to the surrounding terrain. The elevation parameter is optional. Examples of valid coordinates are [-43.2, 80.6] and [12.5, -25.8, 300]. timezone The difference to Greenwich time (GMT) in hours. If omitted or set to 'auto', timezone is extracted from the system. dst Daylight Saving Time: 1 if date is in daylight saving time, 0 otherwise. If omitted or set to 'auto', dst is extracted from the system. format Output time format, according to the following table: Format Description Example 24h 24-hour time format 16:45 12h 12-hour time format 4:45 pm 12hNS 12-hour format with no suffix 4:45 Float Floating point number 16.75 Return Value

getTimes return an associative array containing 9 prayer times (see here for the list of times and their definition). Each time can be accessed thorough its name. For example, if the output of getTimes function is stored in an object times, the time for sunrise can be accessed through times.sunrise.

Example

var times = prayTimes.getTimes(new Date(), [43, -80], -5); document.write('Sunrise : '+ times.sunrise) Set Calculation Method

There are several conventions for calculating prayer times. The default convention used in PrayTimes is Muslim World League. You can change the calculation method using the following function:

setMethod (method) method can be any of the followings:

Method Description MWL Muslim World League ISNA Islamic Society of North America Egypt Egyptian General Authority of Survey Makkah Umm al-Qura University, Makkah Karachi University of Islamic Sciences, Karachi Tehran Institute of Geophysics, University of Tehran Jafari Shia Ithna Ashari (Ja`fari)

More information on the above calculation methods is provided here.

Example

prayTimes.setMethod('Makkah'); Adjusting Parameters

The calculating parameters can be adjusted using the following function:

adjust (parameters) parameters is an associative array composed of any number of the following parameters:

Parameter Values Description Sample Value imsak degrees twilight angle 18 minutes minutes before fajr 10 min fajr degrees twilight angle 15 dhuhr minutes minutes after mid-day 1 min asr method asr juristic method; see the table below Standard factor shadow length factor for realizing asr 1.7 maghrib degrees twilight angle 4 minutes minutes after sunset 15 min isha degrees twilight angle 18 minutes minutes after maghrib 90 min midnight method midnight method; see the table below Standard highLats method higher latitudes adjustment; see below None

asr methods Method Description (more info) Standard Shafii, Maliki, Jafari and Hanbali (shadow factor = 1) Hanafi Hanafi school of tought (shadow factor = 2)

midnight methods Method Description Standard The mean time from Sunset to Sunrise Jafari The mean time from Maghrib to Fajr

higher latitudes methods Method Description (more info) None No adjustments NightMiddle The middle of the night method OneSeventh The 1/7th of the night method AngleBased The angle-based method (recommended)

Example

prayTimes.adjust( {fajr: 16, dhuhr: '5 min', asr: 'Hanafi', isha: 15} ); Tuning Times

You can further tune calculated prayer times (for precaution) using the following function:

tune (offsets) where offsets is an associative array containing time offsets in minutes for each prayer time.

Example

prayTimes.tune( {sunrise: -1, sunset: 3.5} ); Notes: By default, PrayTimes rounds minutes to the nearest values. To round a specific time up, you can tune it by +0.5 minutes, and to round it down, you can tune it by -0.5 minutes. Tuning is the last step after calculating step, and thus, it has no effect on the calculation parameters. For example, if Isha is set to be 90 minutes after sunset, tuning sunset by 5 minutes will not push Isha forward.
