only 2 days in your life aren't 24 hours long
-1
-unless you never cross a time zone.
-2
And twice a year when you move the clock.
No, its the first and last day of one's life.
I would argue that the statement is not accurate for birth/death or for the timezone example (the DST example is actually pretty good still). The only type of day that is 'always' 24 hours long is the
civil/calendar day. The solar day is almost never exactly 24 hours anyway (watch
this for a tidy explanation). So you have to be talking about what we decided is a civil day, which is by its definition a 24 hour period, from midnight to midnight. an individual being born or dying in the middle of the day doesn't change the length of the day. The same is true for timezones and the dateline - the length of the day is the same in any particular place, you're just moving around. In both these examples, the person is 'experiencing' more or less of the defined day. Whereas with DST, the civil definition of that day is 23 or 25 hours.
