For example, my birthday is 9/9. My brothers' birthday is 12/12. Tomorrow will be 3/3. Is there a word that describes when it is the same date as the number we use to represent the month?

Please note that "palindrome" dates usually include the year, so while these numbers are kind of palindromes, I don't think that's the correct word to be applied.

    Palindrome also wouldn't work because 12/21 would be the palindrome in December. An article about your case is here, with a source about as good as you're going to get: wellandgood.com/tiktok-trends-vsp-vision-pure.

  • There doesn't seem to be a clever term - one site calls them repeating dates, and more generally along with palindromic dates, incrementing/sequential dates, and others they can be called fun dates.
