Comprender los calculos de los horarios de oracion
This page explains how Pray.Zone builds prayer times from calculation methods, twilight angles, the Asr juristic setting, and high-latitude adjustments.
Overview
Prayer times begin with your location, date, and time zone. After that, the selected calculation preset decides the twilight angles for Fajr and Isha, the juristic rule for Asr, and the fallback logic used in very high latitudes.
Most users should keep the official method used in their country or city. The custom settings are there for people who want to match a local mosque, council, or school of thought more precisely.
Métodos de cálculo
Each method preset bundles together a known convention for Fajr, Isha, and sometimes special regional adjustments. Choosing a method in the settings drawer automatically fills the related angles, Asr madhab, and high-latitude rule.

Ángulo de Fajr (°)
The Fajr angle is the solar depression used to estimate true dawn. A larger angle usually makes Fajr earlier because it assumes dawn begins while the sun is farther below the horizon.
Ángulo de Isha (°)
The Isha angle is the solar depression used for the night prayer. A larger angle usually makes Isha later because the model waits for deeper twilight before considering nightfall complete.
Madhab de Asr
The Asr juristic setting changes only the Asr prayer. The standard option follows the Shafi'i, Maliki, and Hanbali opinion, while Hanafi uses a later shadow ratio and therefore produces a later Asr time.
Regla de Altas Latitudes
In places where twilight remains for a very long time, or does not fully disappear in some seasons, standard angle-based calculations can become unreliable. High-latitude rules provide a fallback so Fajr and Isha remain usable.
Mitad de la noche
Splits the night in half and uses the midpoint as a practical limit.
Un Séptimo de la Noche
Uses one-seventh of the night as the adjustment window for dawn and nightfall.
Basado en ángulo / 1/60 de la noche
Keeps the twilight-angle idea but scales it to a fraction of the night.
Custom settings
When you change the angles, Asr madhab, or high-latitude rule manually, the site can treat your setup as a custom configuration. That is useful when you want to follow a local mosque timetable rather than a national default preset.
