How long would it take to read a book?
Pages in the book, pages a day — and the day you turn the last one.
You would need
15 active days
- Calendar time
- 15 days
- Finished around
- 16 October 2026
- Pages a week
- 140
Assumptions behind this result
- 20 pages on every active day, 7 days a week, starting today.
- Active days are spread evenly through each week, so the calendar time is an approximation.
Look at the page count, decide how many pages a day is realistic, and see when you would finish. It works just as well for a whole reading list: add up the pages.
How it is worked out
Active days are the total divided by your daily rate, rounded up — a part-finished day still counts as a day.
Calendar time spreads those active days over the week: active days × 7 ÷ days a week, rounded up. The finish date counts today as day one.
