Frequently Asked Questions (Faq)

Could you please provide details on the mathematical formulas employed in the calculation of prayer times?
We rely on the comprehensive research and data available from praytimes.org for our prayer calculations.
What accounts for the variations in Fajr and Isha prayer times compared to other sources?

Kindly verify whether you have experimented with adjusting the "prayer calculation method" and the "high latitude method." These methods are the primary factors contributing to variations in Fajr and Isha prayer timings.

It's important to bear in mind that different prayer times websites may employ distinct formulas and sets of parameters, resulting in varying outcomes. Consequently, prayer times obtained from one source may differ when compared to another, whether that source is another website or a timetable provided by your local mosque.

How accurate are these prayer times?

Prayer times are established through a rigorous calculation and formula that consider multiple factors, including the latitude and longitude of a specific location. Consequently, variations in prayer times can arise when different organizations use these calculations, resulting in approximations that may differ.

Additionally, in regions with high latitudes, discrepancies in prayer times are even more pronounced, particularly during the summer months.

As a result, the introduction of the high latitude method became necessary to provide a practical approximation.

What is the horizon?
The horizon refers to the apparent line where the sky meets the Earth's surface when observed from a specific point. It's essentially the boundary between the sky and the ground or any other surface.
What is dawn?
Dawn is when whitishness starts to appear. The dictionary defines dawn as the time each morning at which daylight first begins.
What is dusk?
Dusk is when it is dark, or when the reddishness in the sky ends. The dictionary defines dusk as the darker stages of twilight.
What is the twilight angle?

To determine Isha and Fajr calculations, one needs to calculate the time when the sun is at a certain distance below the horizon. The twilight angle is used for this purpose and it is defined as the angle in degrees of the sun below the horizon, when total darkness begins or ends.

Some organizations' use a fixed time after Maghrib to determine the start of Isha time.

Several standards have been established for determining Fajr and Isha prayer times.

Egyptian General Authority of Survey:
Region Africa, Syria, Iraq, Lebanon, Malaysia, parts of the USA
Fajr – twilight angle 19.5
Isha – twilight angle 17.5
Islamic Society of North America (ISNA):
Region Parts of the USA, Canada, parts of the UK
Fajr – twilight angle 15
Isha – twilight angle 15
Islamic Organisations Union of France:
Region France
Fajr – twilight angle 12, 15 or 18
Isha – twilight angle 12, 15 or 18
Majlis Ugama Islam Singapura:
Region Singapore
Fajr – twilight angle 20
Isha – twilight angle 18
Muslim world league:
Region Europe, Far East, parts of the USA
Fajr – twilight angle 18
Isha – twilight angle 17
Umm Al Qura:
Region The Arabian Peninsula
Fajr – twilight angle 18.5
Isha – twilight angle 90 minutes after Maghrib (120 minutes during Ramadan)
University of Islamic sciences, Karachi:
Region Pakistan, Bangladesh, India, Afghanistan, parts of Europe
Fajr – twilight angle 18
Isha – twilight angle 18
What is twilight?
Twilight is the name given to the light that is observed after sunset and before sunrise. At this point the sun is below the horizon.
What are Shafi and Hanafi?

These are the 2 schools of thoughts for determining the start of Asar prayer times.

These 2 schools of thoughts use different criteria to determine the start of Asar prayer. They do not affect the timings of the other prayers.

Shafi: The start of Asar is when the shadow of any vertical object exceeds the length of an object.
Hanafi: The start of Asar is when the shadow of any vertical object exceeds twice the length of an object.

Usually Hanafi Asar time is approximately 1 hour later than Shafi Asar prayer time.

How are the times of the prayers determined?

The times of the prayer are determined by the position of the sun, i.e. by defining the above in astronomically measurable terms.

However for countries above 48 degrees (including Britain), Fajr and Isha timings require some estimation as the twilight may persist between sunset and sunrise for certain months of the year.

In these months the sun does not go below the horizon by a sufficient amount and so there is no true night.

Under these circumstances Salahtimes uses the 1/7 rule method by default (for UK) to calculate the Fajr and Isha times respectively, although you can change this to an alternative method.

What are the definitions of the 5 prayer times?

Muslims pray 5 times a day. The times of each prayer vary from place to place and from day to day. It is vital that Muslims perform these prayers at the correct time.

The 5 prayers are described below:

Fajr:
Starts at dawn or morning twilight
Ends just before sunrise

Zohar:
Starts at approximately 5 minutes after Zawaal
Ends at start of Asar time

Asar:
The start of Asar is dependant upon the length of the shadow that is cast by an object. Different schools use different criteria.
Ends just before sunset

Maghrib:
Starts at sunset
Ends at the start of Isha (i.e. when there is reddishness in the sky)

Isha:
Starts after dusk
Ends when the evening twilight disappears (i.e. when it first starts to get light)
