ISO 8601 defines for its purposes midnight as the start of the new day (and end of the old day). But that does mean that since 1582 everyone who uses or used the Gregorian calendar as their civil calendar has/had also used midnight to divide days. Such usages may have exist, they just would not be ISO 8601 compliant.
