Questions people ask
The things that come up about add hourss, answered plainly.
Why is the clock 25 hours later when I added 24?
You crossed an autumn daylight-saving change, where the clocks go back and the civil day is 25 hours long. Adding hours moves along the timeline; the wall clock does not always agree.
What if the result is tomorrow?
It says so. The new date and weekday are shown beside the time, so an overnight result is never mistaken for the same day.
