About Clock Hours:

An hour is the most common time unit people use to read the time. There are two formats of reading clock time, which include:

12 Hour Clock:

This time format includes numbers from 1 to 11 (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11). It either includes AM or PM, which are phases consisting of 12 hours each. Ante Meridiem (AM) stands for the morning time hours, while Post Meridiem (PM) represents the time after noon. Most often, the terms “12 Midnight” & “12 Noon” are used to remember these times.

This concept was introduced in the 2nd Millennium BC and became famous in the 16th century.

24 Hour Clock:

In the 24-hour clock, there is no consideration for AM & PM. The day starts at midnight and ends at the next midnight, comprising 24 hours in total. This is indeed the most modern time system that is accepted globally and recognized by ISO 8601 as well.

How to Calculate Hours Between Two Times?

The step-by-step guide to calculating hours is as follows:

Step 1: Convert to 24-Hour Format

For AM hours, let them as it is

For PM hours, add 12 to the given time

Step 2: Subtract the Start Time from the End Time

Subtract the start time's hours from the end time's hours

Subtract the start time's minutes from the end time's minutes

Step 3: Handle Negative Minutes (Optional)

If the minutes result is negative, borrow an hour from the hours result and add 60 to the minutes.

Step 4: Combine Hours and Minutes

The final result is the number of hours and minutes between the two times.

Example:

Given Times:

Starting Time: 9:00 AM

Ending Time: 3:30 PM

Calculations:

Step 1:

9:00 AM remains 9:00

3:30 PM becomes 15:30

Step 2: 

End Time: 15:30

Start Time: 9:00

Hours: 15 - 9 = 6

Minutes: 30 - 00 = 30

Step 3:

End Time: 10:15

Start Time: 11:45

Hours: 10 - 11 = -1

Minutes: 15 - 45 = -30

Borrow an hour: Hours = -1 + 1 = 0

Add 60 minutes: Minutes = -30 + 60 = 30

Step 4:

Hours: 6

Minutes: 30

Final Result: 6 hours and 30 minutes
