Yes, there is a day in a year that has 25 hours. You can count it yourself if you don’t believe me. Okay. That day is today. The day that we change back hour clocks one hour back. The day when the Daylight Saving Time ends.

At 0200 today we change back the time to 0100. So this one hour repeat itself. I mean not the situation per se, but the clock pass through 0100 twice today. That means there’s an extra hour. That is the hour that makes today 25 hours. I wonder how would it be for any meetings. How would one say when to meet? Or in the television, how would one differentiate both times? When someone say they want to meet at 0130 on October 28, 2008, do they mean the time before or after we change our clocks?

And yes, there are also one day that has only 23 hours. That is the day that we forward the clocks when the DST started. We skip the 0200 to 0300. We lost an hour there. To make it up, we have an extra hour today.
