The Europeans use the month/date/year sequence. As fpr the Julian calendar, well, it sort of is. We use the Gregorian calendar which is a modification of the Julian calendar. By the 1500's, the days had gotten WAY out of sequence with the year. Pope Gregory instituted the change to stay with the celebration of Easter. All Christian nations except for Britain adopted it with the British Empire following in the 1700's. Instead of an hour, people lost 15 days or so. Landlords still charged a months rent though.
