Islamic Prayer Times Explained: When to Pray Each Salah

Why Do Prayer Times Change?

One of the first things new Muslims notice about prayer times is that they are different every single day, and they vary from city to city. This is because Islamic prayer times are not set by a clock. They are determined by the position of the sun in the sky relative to your location on earth.

As the earth orbits the sun throughout the year, the length of daylight changes. In summer, days are longer, so the gap between Fajr and Maghrib stretches out. In winter, days are shorter, and the prayers cluster closer together. If you live in a northern city like London or Toronto, you will notice a dramatic difference between summer and winter prayer times. If you live closer to the equator, the shift is much more subtle.

This is why Muslims rely on prayer time tables or apps rather than fixed schedules. The times are recalculated for your exact location and the current date, ensuring accuracy down to the minute.

The Five Prayers and Their Time Windows

Each prayer has a window of time during which it should be performed. It is best to pray as close to the beginning of the window as possible, but your prayer is valid any time within the window.

Fajr — The Dawn Prayer

Fajr begins at true dawn, which is the moment when the first thin line of light appears across the horizon. This is not the same as sunrise — true dawn occurs well before the sun actually comes up. The Fajr window ends at sunrise. In most locations, this gives you roughly 60 to 90 minutes to pray, depending on the time of year.

Fajr is two rakats (units of prayer), making it the shortest of the five daily prayers. Many Muslims find it the most challenging to pray consistently because it requires waking up before dawn, but it is also described as one of the most rewarding. The quiet stillness of early morning, before the world wakes up, creates a uniquely peaceful environment for connecting with God.

Dhuhr — The Midday Prayer

Dhuhr begins when the sun passes its highest point in the sky (its zenith) and starts to decline. In practical terms, this is shortly after solar noon — not 12:00 PM on the clock, but the actual midpoint of the day based on the sun's position. The Dhuhr window ends when the time for Asr begins.

Dhuhr is four rakats. For many people, it falls during the workday or school hours. Muslims who pray Dhuhr at work often find a quiet room, office, or even an empty conference room. The prayer takes about five to seven minutes once you are familiar with it.

Asr — The Afternoon Prayer

Asr begins when the shadow of an object becomes equal to its actual length (plus the shadow length at solar noon). Different schools of Islamic jurisprudence have slightly different opinions on this: the Hanafi school holds that Asr begins when the shadow is twice the length of the object. This is why you might see two sets of Asr times in some prayer time apps. The Asr window ends just before sunset.

Asr is four rakats. The Prophet Muhammad (peace be upon him) emphasized the importance of not missing Asr, making it a prayer that carries special weight in Islamic tradition.

Maghrib — The Sunset Prayer

Maghrib begins immediately after the sun fully dips below the horizon. The window is relatively short compared to the other prayers — it lasts until the red twilight glow fades from the western sky, which is typically 60 to 90 minutes after sunset. Because of this shorter window, many Muslims prioritize praying Maghrib promptly.

Maghrib is three rakats, making it unique among the five daily prayers (the others are two or four). It is also the prayer at which Muslims break their fast during Ramadan, making it especially meaningful during that month.

Isha — The Night Prayer

Isha begins after the twilight has completely disappeared and the sky is fully dark. The window lasts until the middle of the night (the midpoint between Maghrib and Fajr) according to many scholars, though some extend it until Fajr. Isha is four rakats.

Isha is typically the last prayer of the day. Many Muslims follow Isha with additional voluntary prayers, including the witr prayer, which is a recommended practice especially during Ramadan.

How Location Affects Prayer Times

Because prayer times are based on the sun, your geographic location has a significant impact on your daily schedule.

• Latitude matters. People closer to the poles experience more extreme variations between summer and winter. In northern Europe or Canada, Fajr in summer can be as early as 2:00 or 3:00 AM, while in winter, Isha and Fajr may be relatively close together.
• Longitude matters too. Two cities at the same latitude but different longitudes will have different prayer times because the sun reaches them at different moments.
• Altitude and time zone play smaller but real roles. Higher altitudes can see the sun slightly earlier and later, and time zone boundaries mean that your clock time may not perfectly reflect your solar time.

This is why a generic prayer timetable for an entire country is not accurate enough. You need prayer times calculated for your specific city or, ideally, your exact coordinates.

What If You Miss a Prayer?

Life happens. You might oversleep through Fajr, get stuck in a meeting during Dhuhr, or simply lose track of time. If you miss a prayer, the most important thing is to make it up as soon as you remember or as soon as you are able. A missed prayer that is made up is called qada.

The process for making up a prayer is exactly the same as praying it on time. You perform wudu, face the qibla, and pray the same number of rakats with the same recitations. The only difference is that you are praying it outside of its original time window.

Do not let missing a prayer discourage you. The fact that you feel concerned about it shows that your heart is in the right place. The Prophet Muhammad (peace be upon him) instructed that if someone forgets a prayer or sleeps through it, they should pray it as soon as they remember. There is no sin in genuinely forgetting or oversleeping — the sin would be in deliberately choosing not to pray at all.

As a new Muslim, you are still building your routine. Some days you will catch every prayer on time. Other days you might miss one or two. That is part of the learning process. What matters is that you keep trying, keep improving, and never give up on the habit entirely.

Using Prayer Time Apps and Tools

Given that prayer times change daily and depend on your location, using a prayer time app is practically essential for any practicing Muslim today. A good prayer time app will calculate your exact prayer times based on GPS, send you notifications before each prayer so you can prepare, and adjust automatically as the seasons change.

When choosing an app, look for one that lets you select your calculation method and school of jurisprudence. Different Islamic organizations use slightly different formulas for calculating Fajr and Isha in particular, and using the method recommended by your local mosque ensures your times align with your community.

Revertly includes built-in prayer times that are calculated based on your exact location, with support for multiple calculation methods so you can match the standard used by your local community. It sends you gentle reminders for each prayer, helping you build and maintain your prayer routine as you learn.

Building Your Prayer Routine

Knowing when to pray is the first step. The second step is building a routine that makes it natural. Here are a few tips that many Muslims find helpful:

• Start with the prayers that fit your current schedule best. If you are already awake during Dhuhr and Asr, start there. Add the others as your routine develops.
• Set alarms or notifications. Until praying at the right time becomes second nature, let your phone remind you. Many Muslims keep prayer notifications on for years, even after they are experienced.
• Pray at the same spot each day. Having a dedicated prayer space — even just a corner of a room with a mat laid out — reduces friction and makes it easier to start.
• Be consistent before being perfect. Praying five times a day, even imperfectly, is far more valuable than waiting until you have every Arabic word memorized. Build the habit first. The refinement comes naturally with repetition.

The five daily prayers are the rhythm of a Muslim's life. They mark the passage of each day with moments of stillness, gratitude, and connection. As you learn when each prayer falls and begin praying them consistently, you will discover that they do not just structure your day — they transform it.
