A happy number is defined as a number that eventually reaches 1 when replaced repeatedly by the sum of the squares of its digits. For 1776, the process is as follows: 1² + 7² + 7² + 6² = 1 + 49 + 49 + 36 = 135. Continuing this process, 135 does not lead to 1, which means 1776 is not a happy number. Therefore, 1776 is not a happy number.
