Pray Times

Islamic project aimed at providing a Dart library for calculating Muslim prayers times.

Usage

import 'package:pray_times/pray_times.dart';

main() {
  double latitude = 31.7775067;
  double longitude = 35.2368801;
  double timezone = 2;

  PrayerTimes prayers = new PrayerTimes();
  prayers.setTimeFormat(prayers.Time24);
  prayers.setCalcMethod(prayers.MWL);
  prayers.setAsrJuristic(prayers.Shafii);
  prayers.setAdjustHighLats(prayers.AngleBased);
  var offsets = [0, 0, 0, 0, 0, 0, 0];
  prayers.tune(offsets);

  final date = DateTime(2023, DateTime.january, 20);
  List<String> prayerTimes =
  prayers.getPrayerTimes(date, latitude, longitude, timezone);
  List<String> prayerNames = prayers.getTimeNames();

  for (int i = 0; i < prayerTimes.length; i++) {
    print("${prayerNames[i]} - ${prayerTimes[i]}");
  }
}

Calculation Methods

Name	Fajr Angle	Isha Angle	Maghrib Duration	Description
MWL	18	17		Muslim World League, usually used in Europe, Far East and parts of America. Default in most calculators.
ISNA	15	15		Islamic Society of North America, used in Canada and USA.
Umm al-Qura	18.5		90 minutes	Umm al-Qura University in Makkah which used in Saudi Arabia.
Karachi	18	18		University of Islamic Sciences, Karachi.
Egypt	19.5	17.5		Egyptian General Authority of Survey.
Tehran	17.7	14		Institute of Geophysics at University of Tehran.
Jafari	16	14		Shia Ithna Ashari that used in some Shia communities worldwide.
Custom	0	0		Calculation method for customization .

Madhab

Value	Factor	Description
Shafi	1	Asr begins when the length of any object's shadow equals the length of the object itself plus the length of that object's shadow at noon.
Hanafi	2	Asr begins when the length of any object's shadow is twice the length of the object plus the length of that object's shadow at noon.

High Latitude

In locations at higher latitude, twilight may persist throughout the night during some months of the year. In these abnormal periods, the determination of Fajr and Isha is not possible using the usual formulas mentioned in the previous section. To overcome this problem, several solutions have been proposed, three of which are described below.

Value	Description
MIDDLE_OF_THE_NIGHT	Fajr will never be earlier than the middle of the night and Isha will never be later than the middle of the night
SEVENTH_OF_THE_NIGHT	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
TWILIGHT_ANGLE	Similar to SEVENTH_OF_THE_NIGHT, but instead of 1/7, the fraction of the night used is fajrAngle/60 and ishaAngle/60
