I asked that question once before and did get a reasonable answer as to why (which I can't remember) but also agreement that our system is more logical than the American one.

If you think about it to go from small units to big units gives DD/MM/YY. I suppose the only problem with that system is we work on HH:MM:SS which works the other way round so perhaps the most logical system would be YY/MM/DD which allows the DD to be further divided int HH:MM:SS while retaining the same logic. Either way ,to go MM/DD/YY is completely illogical.
