Prayer 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.

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
