Understanding a.m. and p.m. means interpreting times on the 12-hour clock as parts of one 24-hour day: a.m. identifies times from midnight through the morning before noon, while p.m. identifies times from noon through the evening and night. The same clock reading, such as 7:00, can therefore name two different times, and this distinction supports ordering daily events and interpreting schedules; 24-hour notation and more advanced time-zone conventions are not included.
A day has two parts for each clock number:
So, the clock reading 7:00 can mean two different times:
Example: Maya eats breakfast at 7:00 a.m. and goes to bed at 7:00 p.m. Which event happens first?
Therefore, Maya eats breakfast at 7:00 a.m. first, and she goes to bed at 7:00 p.m. later.
