Oh that is just too funny !,so tell me,without mechanical clocks in
antiquity,how did they determine that the annual cycle is 365 days 5
hours 49 minutes whereby the fractional 5 hour 49 minute difference is
collected to form the leap day correction on Feb 29th of the 4th year.

"They" didn't. Different ancient cultures had different ideas about the
length of a year, some more accurate, some less. And different cultures
adopted different calendar strategies to deal with drift. A leap day in
February is rather recent. Many cultures let things drift for a while
and then added a special out-of-cycle period, or maintained different
types of calendars for different purposes.

Of course, dealing with the non-integral number of days in a year is an
entirely different thing than what everyone else is discussing here,
which is how the calendar is adjusted to compensate for the precession
of the equinoxes.
