Missed Prayer (Qaza) Calculator
Calculate your missed prayers and fasts. Each calculator includes PDF download, a daily table and a plan calculator — all in your browser, with no registration.
How to use the service?
The Qaza calculator is a tool that combines 3 separate calculators. First choose the service you need, then fill in a simple form and start calculating. No registration or data entry is required — everything runs in your browser.
Choose a calculator
Click one of the 3 cards above: Qaza prayer, Qaza fast or the special calculator for women with valid excuses.
Enter your data
Fill in your name and the required dates (Day/Month/Year). For women, additionally — the number of menstruation and postpartum days.
Get the result
Click the "Calculate" button. The result appears instantly: the total count, statistics, a monthly table and a plan calculator.
What does each service do?
- Qaza prayer — 6 prayers are calculated for each day between the date of maturity (puberty) and the date prayers were started. It outputs circles for each day in the form of a monthly table.
- Qaza fast — 30 days for each Ramadan between the year of maturity (puberty) and the year fasting was started. A table with circles lets you check off each fast.
- Women with valid excuses — combines the two calculations above, but produces the result with menstruation and postpartum days deducted.
How does the PDF download work?
After calculating, a "Download PDF" button appears at the bottom of each page. Click the button — the PDF file is automatically downloaded to your computer. The file contains:
- Your personal data (name, dates)
- The total calculated amount
- Circles for each day or each prayer — convenient to print out and mark on paper
Why do you need the plan calculator?
Inside each calculator there is a separate section called "Plan". It asks how many qaza you perform per day (or per week) and automatically calculates when you will finish.
For example: if you have 22,000 qaza prayers and read 6 a day — it will take about 10 years. By changing the number, you can try different options.
Where is my data saved?
Nowhere. This service works 100% in your browser — no data is sent to our server or stored. If you refresh the page or close and reopen it, your entered data is cleared. The PDF is also generated in the browser and goes directly to your computer.
Can it be used on a mobile phone?
Yes. The service is fully responsive — it works the same on phone, tablet and computer. PDF download also works in the mobile browser. Just note: for large calculations (e.g. 10+ years of qaza) PDF generation may take 2–5 seconds.
Frequently asked questions
Is the service free?
Yes, completely free. No payments, subscriptions or hidden costs. You can use it as many times as you like. We also keep advertising to a minimum as much as possible.
Is registration required?
No. Email, phone number or any other data is not needed. Open the page and use it right away.
Will my entered data remain after refreshing the page?
No. If you refresh the page or close and reopen it — all data is cleared. This is intentional: so your personal data is not stored even in the browser. If you want to save the result — download the PDF.
How accurate is the result?
The calculation is mathematically accurate — the days between dates are computed using the Gregorian calendar. But the result is still approximate, because it is difficult to know the exact date of maturity (puberty). To be safe, we recommend setting the date of maturity a little earlier.
Who can I contact if there is an error?
Contact us through the "Contact" section at the top of the site. You can report any suggestion, idea for improvement or an error.
The PDF didn't generate or is too large — what should I do?
If your qaza amount is very large (e.g. 50,000+), PDF generation may take a few seconds and the file may turn out large. Please be patient — while the button shows "Preparing PDF...", the process is running. If it keeps not working, refresh the browser and try again.
Can it also be used on a phone?
Yes. The service is fully adapted to mobile mode: the Day/Month/Year inputs are convenient, tables are scrollable, buttons are large. The PDF downloads in the mobile browser too and goes to the gallery or the "Downloads" folder.
How many kinds of result are shown?
Each calculator has 3 sections:
- Overview / Statistics — the total count and metrics
- Monthly table / Fast circles — visual tracking
- Plan — a calculator for when to finish
Can one of the 3 services be used at once?
Yes. The women with valid excuses calculator actually combines 3 services: qaza prayer + qaza fast + deduction of menstruation and postpartum days. For women, using this one alone is enough.
