To find out how many times the digit 7 appears from 1 to 100, we can break it down into three categories: numbers with a 7 in the units place, numbers with a 7 in the tens place, and the number 7 itself.

There are 10 numbers (7, 17, 27, 37, 47, 57, 67, 77, 87, 97) with 7 in the units place, 10 numbers (70, 71, 72, 73, 74, 75, 76, 77, 78, 79) with 7 in the tens place, and the number 7 itself.

Therefore, the digit 7 appears 19 times from 1 to 100.
