Frequently asked questions

How do I calculate my missed prayers?

Enter the required values into the input fields and press the calculate button. The tool applies the formula Total = (years×354 + months×29.5 + days) × 5; clear days = ⌈total ÷ daily make-up⌉ and returns the result with a short explanation of each step, so you can check the working yourself.

Do I really have to make up years of prayers?

The dominant scholarly view is that missed obligatory prayers must be made up (qadha) regardless of how many accumulate, because the obligation is not dropped by delay. Many scholars combine this with sincere repentance and, where relevant, tawbah. The calculator totals the qadha count so you can build a realistic make-up schedule rather than being overwhelmed.

How do I pray Qadha practically?

Pair each make-up prayer with its current counterpart: after today's Fajr, pray one missed Fajr, and so on through the day — one extra 'day' of prayers daily. Any time outside the brief disliked windows is valid, and grouping several at once is also acceptable. The calculator totals the qadha owed so you can build a sustainable daily make-up schedule.

Is repentance enough without Qadha?

Repentance (tawbah) addresses the sin of neglecting the prayers, but the prayers themselves remain an obligation that most scholars say must still be performed in qadha. The Hanbali and dominant view holds that repentance does not cancel the missed prayers. The calculator shows how many prayers are owed so you can pair sincere repentance with a practical make-up plan.
