 # pray_calc_dart
 
-Islamic prayer times for Dart and Flutter. Implements the MCW seasonal model and dynamic twilight angles. Uses [nrel_spa](https://pub.dev/packages/nrel_spa) for the NREL Solar Position Algorithm.
+Islamic prayer times for Dart and Flutter. Calculates Fajr, Dhuhr, Asr, Maghrib, Isha, midnight, and Qiyam for any date and location. Implements the MCW seasonal model and Dynamic Prayer Calculation (DPC) algorithm. Depends on `nrel_spa` for solar positioning.

+# Advanced Usage
+
+## Madhab Selection
+
+The Asr time differs between the Hanafi and standard (Shafi'i/Maliki/Hanbali) methods:
+
+```dart
+import 'package:pray_calc_dart/pray_calc_dart.dart';
+
+final standard = getTimes(
+  DateTime.utc(2024, 3, 15),
+  40.7128, -74.0060, -5.0,
+  config: const PrayerConfig(madhab: Madhab.standard),
+);
+
+final hanafi = getTimes(
+  DateTime.utc(2024, 3, 15),
+  40.7128, -74.0060, -5.0,
+  config: const PrayerConfig(madhab: Madhab.hanafi),
+);
+
+print('Asr (standard): ${standard.asr.toStringAsFixed(4)} h');
+print('Asr (Hanafi):   ${hanafi.asr.toStringAsFixed(4)} h');
+```
+
+## MCW Seasonal Model
+
+The MCW (Mohammed Camille Widad) seasonal model adjusts Fajr and Isha depression angles across the year to match observed sighting data. This is the default behavior. The DPC (Dynamic Prayer Calculation) variant uses ML-calibrated angles derived from verified sighting observations.
+
+Both models are used automatically based on latitude and date. No configuration is needed.
+
+## Fixed Angle Override
+
+For interoperability with fixed-angle calculation methods (ISNA, MWL, etc.):
+
+```dart
+final times = getTimes(
+  DateTime.utc(2024, 3, 15),
+  40.7128, -74.0060, -5.0,
+  config: const PrayerConfig(
+    fajrAngle: 15.0,   // ISNA
+    ishaAngle: 15.0,
+  ),
+);
+```
+
+## High Latitude Adjustments
+
+At latitudes above 48°N or below 48°S, Fajr and Isha times may behave unusually due to near-continuous twilight. The library applies the Middle of Night method automatically for extreme latitudes. Check `times.fajr.isNaN` to detect fallback conditions.

+# Quickstart
+
+## Install
+
+Add to `pubspec.yaml`:
+
+```yaml
+dependencies:
+  pray_calc_dart: ^1.0.0
+```
+
+Run `dart pub get`.
+
+## First Call
+
+```dart
+import 'package:pray_calc_dart/pray_calc_dart.dart';
+
+void main() {
+  final times = getTimes(
+    DateTime.utc(2024, 3, 15),
+    21.3891,  // Makkah latitude
+    39.8579,  // longitude
+    3.0,      // UTC offset (Arabia Standard Time)
+  );

+  print('Fajr:    ${times.fajr.toStringAsFixed(4)} h');
+  print('Dhuhr:   ${times.dhuhr.toStringAsFixed(4)} h');

+  print('Maghrib: ${times.maghrib.toStringAsFixed(4)} h');
+  print('Isha:    ${times.isha.toStringAsFixed(4)} h');
+}
+```
+
+## Output Fields
+
+`getTimes` returns a `PrayerTimes` object:
+
+| Field | Type | Description |
+| --- | --- | --- |
+| `fajr` | `double` | Fajr time (decimal hours, local) |
+| `dhuhr` | `double` | Dhuhr time |
+| `asr` | `double` | Asr time |
+| `maghrib` | `double` | Maghrib time (sunset) |
+| `isha` | `double` | Isha time |
+| `midnight` | `double` | Islamic midnight |
+| `qiyam` | `double` | Last third of night start |
+
+All times are decimal hours in the local timezone defined by `utcOffset`.
+
+## Converting to DateTime
+
+```dart
+DateTime timeToDateTime(DateTime date, double hours, double utcOffset) {
+  final totalMinutes = (hours * 60).round();
+  final h = totalMinutes ~/ 60;
+  final m = totalMinutes % 60;
+  return DateTime(date.year, date.month, date.day, h, m)
+    .subtract(Duration(hours: utcOffset.truncate(), minutes: ((utcOffset % 1) * 60).round()));
+}
+```
