Reliability
Our service reliability and uptime commitments
Overview
Our goal is simple: provide precise and trustworthy Sehri and Iftar (Maghrib) times for any location worldwide. Accuracy matters because even small errors in time calculation can affect fasting schedules.
We combine peer-reviewed astronomical algorithms, internationally recognised calculation methods, and robust timezone data to ensure reliability.
How Accuracy is Ensured
1. Astronomical Calculations
- • Sunrise, sunset, and twilight times are calculated using NOAA algorithms, validated by modern observation.
- • Fajr times are based on the angle of the sun below the horizon, following multiple Islamic scholarly methods (MWL 18°, ISNA 15°, Umm al-Qura 18.5°, Diyanet 20°).
- • Iftar times are calculated from the exact moment of sunset, adjusted for atmospheric refraction.
2. Timezone Verification
- • Local time is determined using coordinate-based IANA timezone lookup.
- • Daylight Saving Time (DST) is applied automatically where applicable.
- • This prevents errors from simplistic longitude-based or country-only approximations.
3. Fallback & Redundancy
- • If the primary data source (sunrise-sunset API) is unavailable, built-in fallback calculations ensure continuous service.
- • All fallback calculations use the same validated astronomical algorithms to maintain accuracy.
Sanity Checks & Validation
- • Fajr is always confirmed to occur before sunrise.
- • Iftar is verified to occur at sunset.
- • Multiple calculation methods are checked for consistency across global latitudes.
- • Extreme latitude locations (e.g., Alaska, Hawaii, Northern Europe) are validated to avoid physically impossible times.
Edge Cases & Regional Variations
- • Different Islamic schools interpret dawn slightly differently; all recognized methods are supported.
- • Optional user-defined buffer minutes are available to align with local mosque practices.
- • The system automatically accounts for latitude, longitude, elevation, and timezone differences.
Continuous Updates
Astronomical calculations, timezone data, and regional offsets are periodically reviewed and updated. This ensures ongoing accuracy for new years, daylight saving changes, or political timezone adjustments.
Summary
By combining rigorous astronomy, scholarly consensus, and modern software verification, the platform ensures reliable and accurate prayer times for users everywhere. Every calculation is designed to match real-world conditions while respecting traditional observances.
