How It Works
The calculator divides the total number of pages in the book by the number of pages you plan to read each day, then rounds up to the nearest whole day using a ceiling function. Rounding up ensures you never underestimate your timeline — for example, if you need 13.2 days at your chosen pace, the result shows 14 days rather than 13, because the final partial day still counts as a full day of reading. The weeks estimate divides the ceiling-rounded day count by 7 to give you the broader timeline in weeks, expressed to one decimal place. Both results update instantly as you adjust your reading pace or book length. If you want to finish by a specific date, work backwards: count the days until your deadline and use that as the divisor against the total pages to find the minimum daily page target required.
