Yes, but in Roman numerals, not Arabic (MLXVI). The Gregorian calendar was 6 days ahead due to not having leap years yet. The date format wouldn’t matter since it’s just a year being listed.
Probably yes. Dionysius Exiguus invented numbering years since the supposed birth of Christ, instead of counted by era of Roman consuls. So by 1066 the practice would have been common throughout Christian Europe. The only doubts I have are around the introduction of the Gregorian Calendar later, and whether the 14 October 1066 would be counted as the 14 October 1066 in their system. But I think the year would be right.
Would someone from that time recognize 1066 as the year? Were they using modern date formats for years at that time?
