The idea of a single addition/subtraction of a 'leap second' is

astronomical cycle.


Now Gerald, you should realize that sometimes leap seconds
are added (or subtracted) to keep so the civil time and sidereal
day will stay synced, just like we add (or don't add) leap days
to keep the seasons synced with the sidereal year.


The calendar represents the convenience of a linear progression of
years using the equable/average 24 hour day from a raw orbital cycle
and if an individual learned that much they would have achieved a good
day's work.
