The number 1 appears 21 times between 1 and 120. This includes 1 itself, and then it appears in the tens and units places in the numbers 10-19 (10 times) and in the numbers 21, 31, 41, 51, 61, 71, 81, 91, 101, 111 (11 times). Thus, the total count is 1 (from 1) + 10 (from 10-19) + 10 (from 21, 31, etc.) = 21.
