I strongly disagree. Why would you put the number you use the least in the first place?

Month and year change far less frequently, so why prioritize them over the day?

The day is what you use daily, so its proper position is at the beginning. DD/MM/YYYY is the only logical way to write dates.

It doesn't make sense but you are used to it. Just like imperial measure units. They doesn't make any sense but you all use it because you are used to it.
