It may depend on one's mathematical model of reality. Based on my
interpretation of the math taught to me, no day has 24 hours. All days
(excluding special cases) have 23.99999999999999999999.... hours.
At 24, it is no longer the same day. 24 is the start of the next day.
"t" in the expression "0:00 <= t < 24:00" describes the hours in a
day.
However the true answer may depend on answers to the following questions: Is the end of a day, a part of or not a part of the start of the next day? Is time discrete or continuous? Is the universe digital or analog? Received on Thu Nov 11 2004 - 18:02:01 CET
