Introduction

Time is a valuable resource that we all have to manage effectively. Whether you are a student, a professional, or a business owner, understanding time duration is essential to your success. In this article, we will explore how to calculate the time duration between 9am to 1pm.

Calculating Time Duration

Calculating time duration is a simple process that involves subtracting the start time from the end time. In this case, we want to find out how many hours there are between 9am and 1pm.

To do this, we need to convert the time into a 24-hour format. In the 24-hour format, 9am is equivalent to 09:00 and 1pm is equivalent to 13:00. We can then subtract the start time from the end time:

13:00 – 09:00 = 4 hours

Therefore, there are 4 hours between 9am and 1pm.

It is important to note that when calculating time duration, we need to consider the time format. If we were to calculate the time duration between 9am and 1pm in a 12-hour format, we would get a different result:

1:00pm – 9:00am = 4 hours

However, this result is incorrect because it does not take into account the fact that the time format changes from AM to PM. Therefore, it is important to always convert the time into a 24-hour format before calculating time duration.

Conclusion

Calculating time duration is a simple process that can be done by subtracting the start time from the end time. When calculating time duration, it is important to consider the time format and convert it into a 24-hour format before performing the calculation. In the case of 9am to 1pm, there are 4 hours between the two times.
