Quick Examples #

Daily Prayer Times #

Generate and display prayer times for a single day:

import 'package:prayer_timetable/prayer_timetable.dart';
import 'package:timezone/data/latest.dart' as tz;

void main() {
  tz.initializeTimeZones();

  final timetable = PrayerTimetable.calc(
    timetableCalc: TimetableCalc(
      date: DateTime.now(),
      timezone: 'America/New_York',
      lat: 40.7128,
      lng: -74.0060,
      precision: true,
      fajrAngle: 15.0,
    ),
    jamaahOn: true,
    jamaahMethods: ['afterthis', '', 'afterthis', 'afterthis', 'afterthis', 'afterthis'],
    jamaahOffsets: [[0, 15], [0, 0], [0, 10], [0, 10], [0, 5], [0, 15]],
    timezone: 'America/New_York',
  );

  print('=== Prayer Times for ${DateTime.now().toString().split(' ')[0]} ===');

  final prayerNames = ['Fajr', 'Sunrise', 'Dhuhr', 'Asr', 'Maghrib', 'Isha'];
  for (int i = 0; i < 6; i++) {
    final prayer = timetable.current[i];
    final timeStr = prayer.prayerTime.toString().split(' ')[1].substring(0, 5);
    final jamaahStr = prayer.jamaahTime != prayer.prayerTime
        ? ' (Jamaah: ${prayer.jamaahTime.toString().split(' ')[1].substring(0, 5)})'
        : '';
    final status = prayer.isCurrent ? ' [CURRENT]' : prayer.isNext ? ' [NEXT]' : '';

    print('${prayerNames[i].padRight(8)}: $timeStr$jamaahStr$status');
  }

  print('\nNext prayer in: ${timetable.utils.countDown}');
  print('Qibla direction: ${timetable.utils.qibla.toStringAsFixed(1)}°');
}

Terminal Output:

=== Prayer Times for 2025-10-27 ===
Fajr    : 06:15 (Jamaah: 06:30)
Sunrise : 07:42
Dhuhr   : 12:28 (Jamaah: 12:38) [NEXT]
Asr     : 15:45 (Jamaah: 15:55)
Maghrib : 18:14 (Jamaah: 18:19)
Isha    : 19:32 (Jamaah: 19:47)

Next prayer in: 2:15:33.000000
Qibla direction: 58.5°

Monthly Prayer Timetable #

Generate a complete monthly prayer schedule:

import 'package:prayer_timetable/prayer_timetable.dart';
import 'package:timezone/data/latest.dart' as tz;

void main() {
  tz.initializeTimeZones();

  final calc = TimetableCalc(
    date: DateTime(2025, 3, 1),
    timezone: 'America/New_York',
    lat: 40.7128,
    lng: -74.0060,
    precision: true,
    fajrAngle: 15.0,
  );

  // Generate March 2025 prayer times
  final monthlyPrayers = PrayerTimetable.monthTable(
    2025, 3, // March 2025
    calc: calc,
    timezone: 'America/New_York',
    jamaahOn: false,
  );

  print('=== March 2025 Prayer Timetable (New York) ===');
  print('Date       Fajr   Sunrise Dhuhr   Asr     Maghrib Isha');
  print('─' * 58);

  for (int day = 0; day < monthlyPrayers.length; day++) {
    final dayPrayers = monthlyPrayers[day];
    final date = dayPrayers[0].prayerTime;
    final dateStr = '${date.month.toString().padLeft(2, '0')}/${date.day.toString().padLeft(2, '0')}';

    final times = dayPrayers.map((prayer) =>
      prayer.prayerTime.toString().split(' ')[1].substring(0, 5)
    ).toList();

    print('$dateStr       ${times[0]}  ${times[1]}   ${times[2]}   ${times[3]}   ${times[4]}   ${times[5]}');
  }

  print('\nTotal days: ${monthlyPrayers.length}');
}

Terminal Output:

Core Classes #

PrayerTimetable #

Main class with three calculation methods:

Astronomical Calculations

final timetable = PrayerTimetable.calc(
  timetableCalc: TimetableCalc(
    date: DateTime.now(),
    timezone: 'America/New_York',
    lat: 40.7128,
    lng: -74.0060,
    precision: true,
    fajrAngle: 15.0,
    madhab: 'shafi', // or 'hanafi'
  ),
  jamaahOn: true,
  timezone: 'America/New_York',
);

Pre-calculated Maps

final timetable = PrayerTimetable.map(
  timetableMap: yourPrayerTimeMap,
  jamaahOn: true,
  timezone: 'America/New_York',
);

List-based Timetables

final timetable = PrayerTimetable.list(
  timetableList: yourPrayerTimeList,
  differences: monthlyDifferences,
  jamaahOn: true,
  timezone: 'America/New_York',
);

Prayer Object #

Each prayer contains timing and status information:

Prayer fajr = timetable.current[0]; // Prayer IDs: 0-5
print('${fajr.name}: ${fajr.prayerTime}');
print('Jamaah: ${fajr.jamaahTime}');
print('Current: ${fajr.isCurrent}');
print('Next: ${fajr.isNext}');

Prayer IDs:

• 0: Fajr, 1: Sunrise, 2: Dhuhr, 3: Asr, 4: Maghrib, 5: Isha

Utils Class #

Prayer analysis and Islamic calculations:

Utils utils = timetable.utils;
print('Next prayer in: ${utils.countDown}');
print('Prayer completion: ${utils.percentage}%');
print('Qibla direction: ${utils.qibla}°');
print('Hijri date: ${utils.hijri}'); // [year, month, day]

Hijri Calendar Integration #

Comprehensive Hijri calendar conversion utilities:

// Date conversions
DateTime gregorian = Utils.hijriToGregorian(1446, 9, 26);
var hijri = Utils.gregorianToHijri(DateTime(2025, 3, 26));

// Month operations
DateTime ramadanStart = Utils.getHijriMonthStart(1446, 9);
int ramadanDays = Utils.getHijriMonthLength(1446, 9);

// Formatting and names
String formatted = Utils.formatHijriDate(1446, 9, 26); // "1446-09-26"
String monthName = Utils.getHijriMonthNameEnglish(9);  // "Ramadan"
String arabicName = Utils.getHijriMonthNameArabic(9);  // "رمضان"

Jamaah Configuration #

Customize congregation prayer times:

final timetable = PrayerTimetable.calc(
  timetableCalc: calc,
  jamaahOn: true,
  jamaahMethods: ['fixed', '', 'afterthis', 'afterthis', 'afterthis', 'afterthis'],
  jamaahOffsets: [
    [6, 0],    // Fajr at 6:00 AM (fixed)
    [0, 0],    // Sunrise (no jamaah)
    [0, 15],   // Dhuhr + 15 minutes
    [0, 15],   // Asr + 15 minutes
    [0, 5],    // Maghrib + 5 minutes
    [0, 20]    // Isha + 20 minutes
  ],
  jamaahPerPrayer: [true, false, true, true, true, true],
  timezone: 'America/New_York',
);

Monthly Timetables #

Generate complete monthly schedules for both Gregorian and Hijri calendars:

// Gregorian month
List<List<Prayer>> marchPrayers = PrayerTimetable.monthTable(
  2025, 3, // March 2025
  calc: timetableCalc,
  timezone: 'America/New_York',
);

// Hijri month
List<List<Prayer>> ramadanPrayers = PrayerTimetable.monthHijriTable(
  1446, 9, // Ramadan 1446 AH
  calc: timetableCalc,
  timezone: 'America/New_York',
);
