Question 1

How are Islamic prayer times calculated?

Accepted Answer

Islamic prayer times are calculated based on the sun's position relative to specific angles: Fajr (dawn): when light first appears horizontally; Dhuhr (noon): when the sun passes its zenith; Asr (afternoon): when shadow equals object length (Shafi'i) or twice object length (Hanafi); Maghrib (sunset): when sun disappears; Isha (night): when redness disappears. These calculations consider latitude, longitude, date, and altitude.

Question 2

Why do prayer times vary between different mosques and apps?

Accepted Answer

Variations occur due to: 1) Different calculation methods (University of Islamic Sciences Karachi, Muslim World League, Egyptian General Authority, etc.), 2) Juristic opinions on Asr timing (Shafi'i vs. Hanafi schools), 3) Different angles used for Fajr and Isha (typically 15-18° for Fajr, 15-18° for Isha), 4) Local mosque adjustments for community convenience, and 5) Manual vs. astronomical calculations.

Question 3

What is the best calculation method for my location?

Accepted Answer

The appropriate method depends on your location and juristic school: The Muslim World League method works well for most mid-latitude regions; University of Islamic Sciences Karachi is common in South Asia; Egyptian General Authority is used in Africa and parts of the Middle East; North America (ISNA) is optimized for North America. Many calculators allow you to compare methods and follow what your local mosque uses.

Question 4

How do extreme latitudes (like Scandinavia) affect prayer times?

Accepted Answer

In extreme latitudes (above 48.5°), conventional prayer time calculations can result in very short or non-existent nights in summer (affecting Isha/Fajr) or very short days in winter. Special methods apply: 1) Nearest latitude (use times from 45° or 48.5°), 2) Nearest day (use times from nearest normal day), 3) One-seventh of night method (divide night into 7 parts), or 4) Local consensus methods established by Muslim communities in those regions.

Question 5

What is Qibla direction and how is it determined?

Accepted Answer

Qibla is the direction Muslims face during prayer—toward the Kaaba in Mecca. It's calculated using spherical trigonometry based on your latitude/longitude and Mecca's coordinates (21.4225°N, 39.8262°E). The direction varies worldwide: east-southeast in North America, south in Europe, northwest in Southeast Asia. Quality prayer time calculators include Qibla direction based on your precise location.
