FAQ

How do you add time that crosses the hour?

Add the hours, then the minutes. If the minutes reach 60 or more, change 60 minutes into one more hour: 2:45 + 30 minutes = 2:75 = 3:15.

What changes when the time crosses noon or midnight?

The clock starts again at 12, and a.m. changes to p.m. at noon (or p.m. to a.m. at midnight). 11:30 a.m. plus 2 hours is 1:30 p.m.
