BOOKENDS puzzle #2, October 29, 2026

That Thursday's BOOKENDS word was CALENDAR. It has eight letters, starts with C and ends with R. The day's shelf held 800 words that fit between the bookends at the start.

What it means: noun: a system of timekeeping that defines the beginning and length and divisions of the year.

Tip for this word: a word starting with C sits about 12% of the way through the alphabet, so a first guess near the middle of the dictionary, such as a word that starts with M, cuts about half the shelf whichever side the answer is on. Aim each later guess at the middle of the gap that is left.
