A few centuries ago, Muslims predicted the prayer timings by looking at the Sun.

But today, you visit a website, like prayertimes.org, open some app, like Muslim Sadiq, and no matter what corner of Earth you live in, you get the most accurate prayer timing.

So, this article is going to be interesting because …

We will discuss all the methods and calculations these websites or apps use to give you accurate prayer times!

Let’s dive in!

Overview of Prayer Time Calculation

It’s fascinating to learn how Muslim prayer times are calculated. The precise tracking of the Sun’s position in relation to specific geographical coordinates – latitude, longitude, and altitude – is at the heart of this complex process.

Accurate calculation methods ensure that devout Muslims perform their daily Salah at the correct times according to Shari’ah Compliant Calculations.

Furthermore, websites like prayertimes.org provide top class widgets for prayer times to programmers, so they can easily include them in their websites, further integrating faith into modern-day technologies.

Definitions and Concepts in Prayer Time Calculation

In this section, we will explore key definitions and concepts that are essential to understanding prayer time calculation. From twilight and solar altitude to the factor of shadow length at Asr, we’ll dive into how these elements influence accurate prayer times.

Twilight and Solar Altitude

Twilight is the time between sunrise and sunset when there is still some light in the sky. The solar altitude, or the height of the Sun above the horizon, is considered when calculating prayer times.

This is important in determining the Fajr (dawn) and Isha (nightfall) prayer times. For example, Fajr is calculated based on when the horizontal spread of morning light reaches a certain level. On the other hand, Isha is determined by different criteria, such as the disappearance of Shafaq (twilight).

Accurate prayer times for Muslims worldwide can be calculated by considering twilight and solar altitude.

Factor of shadow length at Asr

The Asr factor of shadow length is critical in prayer time calculation methodology. It assists in determining the exact timing of the Asr prayer based on the length of an object’s shadow reaching a particular factor.

This factor is calculated by adding the object’s length to its shadow at noon. Using this measurement, prayer calculators can accurately determine when Asr should be performed, ensuring Muslims perform their prayers on time.

Latitudes

At latitudes above 60°, where there are periods of perpetual day or night, another method known as Sab’u Lail, or the 1/7th of the night rule, calculates Fajr and Isha prayer times.

Factors that Influence Prayer Times

Latitude, longitude, elevation, and time zone of the target location all play a role in determining accurate prayer times.

Latitude of target location

The latitude of the target location is critical in the methodology for calculating prayer times. Different latitudes necessitate different calculations to determine accurate timing for Fajr, Dhuhr, Asr, Maghrib, and Isha prayers.

For example, locations closer to the equator have shorter twilight periods and have different requirements for Fajr and Isha prayer times.

Longitude of target location

The longitude of the target location is critical in calculating precise prayer times. The time difference from the standard meridian  (usually Greenwich Mean Time GMT) will affect when the Sun rises and sets, depending on where you are.

Cities located westward, for example, have later sunset times than cities located eastward. If you live in Riyadh, Saudi Arabia (longitude 46°E), your prayer times will differ from those in Miami, Florida (longitude 80°W).

This is an important consideration when determining your daily prayer schedule.

Time zone of target location

The target location’s time zone is an essential factor that influences prayer times. Based on its longitudinal position, each world region has its time zone. This means there will be a difference in local time as you move from one time zone to another.

Because prayer times are determined by the position of the Sun and other celestial bodies, it is critical to consider the correct local time when calculating prayer times for a specific location.

Detailed Calculation Process

The detailed calculation process involves converting the date to Julian Days, calculating the Sun’s declination, determining the equation of time, finding transit time, and calculating the Sun’s altitude for each prayer time.

Conversion of date to Julian Days

One of the first steps in accurately calculating prayer times is converting the date to Julian Days. Julian Days is a count of days that began on January 1st, 4713 BC. This conversion facilitates mathematical calculations and date comparisons.

Calculation of Sun declination

Calculating the declination of the Sun is an essential step in determining accurate prayer times. The angle between the equatorial plane and the path of the Sun in the sky is referred to as sun declination.

It varies throughout the year due to the tilt of the Earth’s axis. We can calculate the Sun’s declination to see how high or low it will be in the sky at different times of the day.

This information is critical for accurately calculating prayer times because it allows us to understand when specific events, such as Fajr and Maghrib, occur as a result of sunrise and sunset.

Calculation of equation of time

Calculating the time equation is an important step in determining accurate prayer times. This calculation considers the difference between solar time and clock time due to the Earth’s elliptical orbit around the Sun.

The equation of time accounts for variations in the length of a day over a year caused by factors such as the Earth’s axial tilt and noncircular orbit.

Prayer times can be adjusted to align with accurate solar positions by accurately calculating the time equation.

Calculation of local noon

Calculating local noon is critical. The Sun’s transit time is when it crosses the observer’s meridian and reaches its highest point in the sky.

This event is critical for calculating the Dhuhr prayer. Precise prayer times can be determined by accurately calculating this transit time and other factors such as latitude and longitude, elevation, and time zone.

Calculation of Sun altitude for each prayer time

Knowing the Sun’s angle above the horizon for each prayer is critical.

The Sun’s altitude varies throughout the day, peaking at noon and gradually decreasing until it sets. Precisely measuring these angles ensures that Muslims can perform their prayers at the appropriate times.

Final calculation of prayer times

After going through the detailed calculation process, the final step is to determine the prayer times based on the calculated data. This entails using specific criteria for each prayer and taking into account factors such as the target location’s latitude, longitude, elevation, and time zone.

Fajr prayer time, for example, is determined by the horizontal spread of morning light in the sky, whereas Dhuhr prayer time is calculated when the Sun begins to fall after reaching its highest point.

Special Considerations for High Latitudes

High latitudes require special considerations in prayer time calculations.

Middle of the night method

In areas with higher latitudes, one of the methods used to determine Fajr and Isha prayer times is the middle-of-the-night method.

This method accounts for the longer nighttime duration in these regions by dividing the night into two halves and using the middle point as the time for Fajr prayer.

It provides a more straightforward and more practical method for accurately calculating prayer times in areas where nighttime can last much longer.

One-seventh of the night method

The “One-seventh of the night method” is a calculation method designed specifically for locations above 60° latitude with long periods of daylight or darkness. This method divides the night into seven equal parts to ensure accurate prayer observation, whether light or dark, regardless of how long it is.

It is a practical solution for people who live in cities with obstructions and light pollution, as well as in areas where accurate prayer calculation may not be possible.

The One-seventh-of-the-night method demonstrates Islamic practices’ adaptability to different geographical circumstances, facilitating prayer times even in areas with unique challenges.

Angle-based method

Rather than relying solely on standard angles for the Sun’s disappearance below the horizon, this method takes into account the specific angle at which the sun sets relative to an observer’s location.

This angle can accurately determine prayer times, even in regions where the Sun does not fully set during certain seasons. This ensures that Muslims in these areas can pray at the appropriate times throughout the year.
