When it comes to dates of birth and death, we have different systems. US records tend to be month-day-year. European records tend to be day-month-year.
I think both systems should be replaced with year-month-day.
There are two reasons for this:
Logic. A year is the largest unit; then the month; then the day.
Microsoft sort filters only work properly with year-month-day.
In the long run, it will help everyone if we transition to a system that is logical and universal.
