Actually, I disagree that DD/MM/YYYY even qualifies as being small to big.

If you actually treat it as a counter from 01/01/2024 onward, note that the first digit that moves is actually the second digit in the 8-digit representation. In terms of significance, the most significant digit is the 5th one in the string, then counting down the significance it’s 6th, then 7th, then 8th, then jumps back to the 3rd, then the 4th, then the 1st, then the 2nd.
