So, the generic worldwide standard is DD/MM/YYYY.
Of course in the US, we state it as MM/DD/YYYY.
But when did the worldwide standard change? And for that matter when did the US decide which we were doing.
The old English statement of date was, for example, "On this day of December the 25th" or, more simply "December the 25th". But older US documents frequently reference "The 25th December" or "This, the 25th day of December".
I don't know why I'm thinking about this.
