Astronomical Islamic Prayer Times & Qibla Direction Studio
Astronomical Islamic Prayer Times Studio delivers daily prayer schedules and Qibla directions by querying the public Aladhan API according to your selected city or user-consented GPS coordinates, paired with client-side session caching and real-time countdown tracking. It provides Fajr, Sunrise, Dhuhr, Asr, Maghrib, and Isha times calibrated to astronomical solar calculation standards.
Users can select recognized calculation conventions: Muslim World League (MWL), Islamic Society of North America (ISNA), Egyptian General Authority, Umm Al-Qura University Makkah, and Diyanet Turkey. Method #13 applies Diyanet Turkey solar angle conventions (Fajr 18.0°, Isha 17.0°); note that official mosque calendars in Turkey incorporate localized administrative temkin adjustments, so users should verify against local mosque schedules. Geolocation detection is strictly optional and only queried upon explicit user confirmation; manual city selection works completely without location permissions.
Concrete Scenario: A traveler in Berlin selects the Muslim World League calculation method with standard Asr. The studio queries the Aladhan timing endpoint, caches the schedule in browser session memory, and presents solar transit, sunset/Maghrib, twilight times, and a live countdown badge indicating the remaining time until the next prayer.
Prayer schedule data is cached in client session memory during your browser session to eliminate redundant network round-trips. Kaaba Qibla direction is computed entirely locally in the browser using Great Circle spherical trigonometry.
Best Practices & Essential Guidelines
- Select the calculation convention officially recognized in your geographic region (e.g. Diyanet in Turkey, ISNA in North America, MWL in Europe) for consistent local scheduling.
- Toggle between Standard (Shafi'i/Maliki/Hanbali) and Hanafi school settings for Asr prayer time to match your community's practice.
- Apply high-latitude adjustments during summer months in locations north of 48° latitude when twilight persists through the night.
- Ensure device system time is accurate, as the live countdown timer syncs against your local device clock.
