Friday Prayer Time Calculator — Free Online Jummah Schedule Tool

How to Use the Friday Prayer Time Calculator

1. Enter your latitude and longitude: Input your geographic coordinates in decimal degree format. The default values are set to New York City (40.7128, -74.0060). To find your coordinates, open any mapping application on your phone or computer, locate your area, and note the latitude and longitude values. Northern latitudes are positive numbers and southern are negative. Eastern longitudes are positive and western are negative. For the most accurate results, use the coordinates of your mosque or the location where you will attend Jummah.
2. Select your calculation method: Choose the prayer time calculation method recognized in your region from the dropdown. ISNA is the standard for North America, MWL is widely recognized internationally, the Egyptian General Authority method is prevalent in Africa and the Middle East, and the University of Karachi method is used throughout South Asia. While Dhuhr time (the basis for Jummah) is identical across all methods, your choice affects Fajr and Isha times displayed in the full schedule.
3. Enter the date: Input the specific year, month, and day. The calculator automatically detects whether your selected date falls on a Friday. If it is not a Friday, it displays how many days remain until the next Friday and shows the date. This helps you quickly look up the upcoming Jummah without manually finding the next Friday.
4. Review the Jummah schedule: The results panel displays a highlighted green section showing the complete Jummah schedule: the estimated khutba start time (approximately 30 minutes before Dhuhr), the Dhuhr prayer time when the actual prayer begins, the estimated conclusion time, and when the permissible window closes at Asr. Below this section, all five daily prayer times are listed for your complete day's schedule.

The calculator updates results instantly as you change any input. The khutba start time is an estimate based on common mosque practice. Your local mosque may begin earlier or later. Always check with your mosque for their specific Jummah schedule, and use this calculator as a reference for the astronomical prayer window.

Jummah Prayer Time Formula

Variables Explained

• Dhuhr / Solar Noon: The exact moment when the sun crosses the local meridian (highest point in the sky). This is the fundamental reference time for the Jummah prayer and marks the beginning of the Dhuhr prayer period. It is calculated from solar transit using the observer's longitude and the equation of time correction.
• Longitude: Your east-west position on Earth, measured in degrees from the Prime Meridian. Each degree of longitude corresponds to 4 minutes of time difference. This value shifts the solar noon calculation from Greenwich Mean Time to your local position.
• EqT (Equation of Time): A correction factor in minutes that accounts for Earth's elliptical orbit and axial tilt. It ranges from approximately -14 minutes in February to +16 minutes in November, causing solar noon to drift from clock noon throughout the year.
• Timezone: The UTC offset for your location, automatically detected from your device's settings. This converts the calculated UTC time to local time. During daylight saving time, this value shifts by one hour.
• Shadow Ratio: The ratio of an object's shadow length to its height at which Asr begins. The Shafi'i and Hanbali schools use a ratio of 1 (shadow equals the object's height plus the shadow at noon), while the Hanafi school uses a ratio of 2. Our calculator uses a ratio of 1, which is the majority opinion.

Step-by-Step Example

Calculate the Jummah prayer time for Chicago (41.8781° N, 87.6298° W) on a Friday in March 2026:

1. Calculate the equation of time for mid-March: approximately -9 minutes
2. Calculate solar transit: 12:00 - (-87.6298/15) - (-9/60) = 12:00 + 5.842 + 0.15 = 17.99 UTC hours
3. Apply timezone (CST = UTC-6): 17.99 - 6 = 11.99 hours = approximately 12:00 PM CST
4. Dhuhr time: 12:00 PM CST
5. Estimated khutba start: 12:00 PM - 30 min = 11:30 AM
6. Estimated Jummah end: 12:00 PM + 45 min = 12:45 PM

In this example, the permissible window for the Jummah prayer extends from Dhuhr at 12:00 PM until Asr (approximately 3:15 PM in March for Chicago). Most mosques schedule the khutba and prayer in the early part of this window for the convenience of attendees.

Practical Examples

Example 1: Hassan's Work Schedule Planning in Houston

Hassan works in downtown Houston and needs to coordinate his Friday lunch break with Jummah prayer. He enters the coordinates for Houston (29.7604, -95.3698) with the ISNA method for the current Friday. The calculator shows Dhuhr at approximately 12:20 PM CST with a khutba start estimate of 11:50 AM. His nearest mosque starts the khutba at 12:00 PM, closely matching the estimate. Hassan arranges with his manager to take his lunch break from 11:45 AM to 1:00 PM every Friday, giving him enough time to drive to the mosque, attend the prayer, and return. He bookmarks this page to check times throughout the year since Dhuhr shifts by up to 30 minutes between summer and winter.

Example 2: Maryam Comparing Jummah Times Across Multiple Cities

Maryam is a consultant who travels frequently between Los Angeles (34.0522, -118.2437), Dallas (32.7767, -96.7970), and Miami (25.7617, -80.1918). She uses the calculator to find the Dhuhr time for each city on the same Friday. Los Angeles shows Dhuhr at approximately 12:05 PM PST, Dallas at 12:25 PM CST, and Miami at 12:15 PM EST. Despite being in different time zones, all three times represent the same astronomical event: the sun crossing each city's meridian. Maryam saves these times to plan her Friday travel schedules so she can always attend Jummah regardless of which city she is visiting. She selects ISNA for all three since she prefers consistency in her prayer schedule.

Example 3: Ibrahim in Oslo During Summer

Ibrahim lives in Oslo, Norway (59.9139, 10.7522) and uses the calculator to check Jummah timing for a June Friday. At this far-northern latitude, the calculator shows significantly different times from what he experiences in winter. Summer Dhuhr in Oslo is approximately 12:40 PM, giving a comfortable midday Jummah. However, he notices that Fajr is extremely early at around 1:30 AM and Isha is past 11:00 PM, meaning his daily prayer schedule is spread over nearly 22 hours. For Jummah planning, the Dhuhr and Asr times give him a generous window of approximately 4 hours. His mosque schedules the summer Jummah at 1:30 PM, slightly after Dhuhr, to accommodate congregants coming from work.

Example 4: Nadia at a University Campus

Nadia is a university student in Ann Arbor, Michigan (42.2808, -83.7430). Her campus Muslim Student Association organizes Jummah prayer, and she uses the calculator with the ISNA method to help plan the semester's prayer schedule. For a February Friday, Dhuhr falls at approximately 12:45 PM EST, but by April it shifts to 1:30 PM EDT due to daylight saving time. The MSA adjusts their Jummah schedule each semester: 12:30 PM in winter months and 1:15 PM in spring and fall. Nadia schedules her Friday classes around these times, ensuring she has a two-hour gap from 12:15 PM to 2:15 PM every Friday. She shares the calculator link with other students who need to plan their course schedules around Jummah.

Tips and Complete Guide

Maximizing the Spiritual Benefit of Jummah

Friday holds special significance in Islam as the best day of the week. To maximize its spiritual benefit, arrive at the mosque early to perform voluntary prayers and recite Quran before the khutba begins. Reciting Surah Al-Kahf (Chapter 18) on Friday is a recommended practice. Performing ghusl (ritual bath) before Jummah, wearing clean and pleasant-smelling clothes, and applying perfume are all established Sunnahs. Use the Qibla Finder if you need to verify the prayer direction at an unfamiliar location. Making abundant supplications (dua) during the last hour before Maghrib on Friday is particularly emphasized, as the Prophet Muhammad mentioned a special time on Friday when prayers are answered.

Understanding Seasonal Prayer Time Shifts

Dhuhr time shifts throughout the year due to the equation of time and daylight saving adjustments. In most locations, Dhuhr varies by approximately 30 minutes between its earliest and latest occurrences during the year. When daylight saving time begins in spring, clock-based prayer times shift forward by one hour even though the sun's position has not changed. This means a mosque that held Jummah at 12:30 PM in winter may shift to 1:30 PM after the spring clock change. Check this calculator periodically throughout the year, especially around the daylight saving transitions in March and November, to keep your Jummah schedule current. The calculator accounts for your device's current timezone setting automatically.

Finding Jummah Prayer While Traveling

When traveling to a new city, this calculator is particularly valuable for planning your Friday prayer. Enter the coordinates of your hotel or workplace in the destination city to get the local Dhuhr time. Then search online for nearby mosques that offer Jummah prayer. Many mosques worldwide list their Jummah times on their websites or social media pages. In cities with large Muslim populations, there are often multiple Jummah congregations at different times to accommodate various schedules. Airport chapels and prayer rooms in some countries also host Jummah services for traveling Muslims. If you cannot locate a mosque, the calculator's times help you pray Dhuhr individually at the correct time.

Common Mistakes to Avoid

• Assuming the same Jummah time year-round: Dhuhr shifts by up to 30 minutes throughout the year, and daylight saving time adds an additional hour shift. Check the calculator periodically rather than relying on a memorized time from months ago.
• Arriving after the khutba has started: The Prophet Muhammad emphasized arriving early for Jummah. If you arrive during the khutba, sit down quietly and listen. If you arrive after the prayer has begun, join for whatever portion you can catch. Missing both rakaat means you must pray the full four-rakaat Dhuhr instead.
• Praying Jummah outside the permissible window: Jummah must be prayed between Dhuhr and Asr. A prayer performed before Dhuhr time is not valid as Jummah. Some mosques start the khutba before Dhuhr but ensure the actual prayer begins after Dhuhr enters.
• Confusing calculator times with mosque schedules: The calculator shows astronomical prayer times. Your mosque's schedule may differ by several minutes. Use the calculator as a reference and always follow your mosque's announced times for the congregation.
• Not accounting for travel time: Plan to arrive at the mosque well before the khutba starts. Factor in commute time, parking, and ablution (wudu). Setting a reminder 45 minutes before the estimated khutba start is a good practice.
