Qada calculator

Qada means making up an obligatory prayer after its time has passed. This calculator helps you estimate how many prayers that might be, so you can plan a pace you can keep.

No. Scholars advise an honest best estimate when the exact number is not known, and the dates of the prayers do not need to be known. If you are unsure, many scholars say to lean toward the higher number. Any extra prayers you make up count as voluntary prayers.

Most scholars say yes, together with sincere repentance (tawba). A smaller group of scholars, including Ibn Hazm, held that a prayer left on purpose cannot be made up and calls for repentance and extra good deeds instead. Both views agree that repentance is needed. Ask a scholar you trust which applies to you.

No. Scholars agree that prayers in the days of menstruation are not made up, and the sources we used say the same for postpartum bleeding (nifas). That is why the calculator has a field for days excused each month. Set it to None if it does not apply to you.

In the Hanafi school Witr is wajib, so it is counted and made up. In the other schools it is a strongly encouraged sunnah. The box is off by default. Turn it on if you follow the Hanafi school, or if a scholar advises it.

Many scholars advise making them up steadily and without needless delay, at a pace you can keep. One suggestion is one make-up prayer with each daily prayer. Rules on order differ between schools and depend on how many there are, so ask a scholar about yours.

No. The estimate is worked out in your browser. Nothing you enter is saved, stored or sent to Niyat or anyone else.

It counts the days between the date you became accountable and the date you began praying regularly, takes away days excused each month, and multiplies what is left by how often you prayed in between: rarely 80 percent, sometimes 50 percent, often 20 percent of days still to make up. The total is rounded to the nearest 5 for large numbers. It is a rough guide, not a ruling.
