Your best friend tells you he or she is leaving on a cruise at "midnight" on May the 10th. What day should you arrive at the dock in time to say bon voyage? Should you arrive on May the 9th (assuming he or she is leaving at the very beginning of the 10th)? Or should you arrive on the 10th (assuming he or she is leaving at the end of the 10th)? Are you absolutely sure?

That's why even though not correct time-wise, it is often better to use approximations:

* 11:59 PM or 12:01 AM, or

* 23:59 or 0:01 (24-Hour Clock)

That's what railroads and airlines do. Even the military! They can't afford confusion.

The above is an example of something we all know, but don't always know that we know: conventional timekeeping has holes that can get us very confused. Here is another one... While you know what 12:20 A.M. and 12:20 P.M. are, you do not know what 12:00 A.M. and 12:00 P.M. are. You can't. Because just as dividing by zero is an undefined mathematical operation, so too neither 12:00 A.M.or P.M. are defined. By the way, the conventional solution to this 12:00 A.M. or P.M. problem is simply to say 12:00 Noon in the day and 12:00 Midnight if at night. But even that does not always end the confusion. Because that leads us back to the confusion which began this page. Fortunately, YOUR "customized to your place in time and space" free KinderClock has been designed to lead you out of this confusion.

Even better, as you will see further on in this site, your KinderClock addresses far more disorienting aspects of what has become, over the past seven hundred years, today's ever more unnatural "corporate" way of looking at and telling time.
