How to use it and understand the result
Use the page count in your own edition. The editable default of 604 is an example; Quran editions, translations and commentaries do not all have the same pagination. Enter 0 for the last completed page to start at page one.
The tool distributes remaining pages as whole numbers. For 604 pages over 30 days, the first four days have 21 pages and the remaining 26 have 20. It never skips or duplicates a page. If days exceed remaining pages, it assigns one page per day and finishes early.
If you miss a day, enter the last page you finished, a new start date and your remaining days to recalculate. This schedule is not a religious obligation, a recommended speed or an automatic completion record. Allow time for studying meaning and pronunciation too.
