Understanding with Example

When someone says it’s 8 AM, it means that the me is 8 O’ Clock in the morning. So, from 12 at night to 12 in the noon (exactly at 11:59 AM), it represents the day clock.

Similarly, when someone says it is 8 PM, it means that the me is 8 O’ Clock in the evening. Hence, from 12 in the noon to 12 at midnight (precisely,11:59 PM), it is the night clock.

AM: It represents time from midnight to noon. (12:00 AM to 11:59 AM). For example: If you say that you have to go to school at 11 AM, it means 11 O’clock in the morning.

PM: It represents time from noon to just before midnight. (12 Pm to 11:59 PM). For example: If you say that you have to take dinner at 9 PM, it means 9 O’clock in the night.
