The actual battle was 1st July
Of course that was the Julian Calender, in 1752 the Gregorian Calender was introduced and added 11 days to prior dates ..... hence the 12th July celebration.
Of course that raises a whole new set of questions as to which dates have been corrected and which not... as different countries adopted the Gregorian system at different times.
I suspect that there was also a lot of chanting
