# Time Duration Calculator

Use our free Time Duration Calculator which helps to find the time duration between two different times in four different formats: HH:MM:SS format or Hours only or Minutes only or Seconds only.
Within this user-friendly tool, you can effortlessly configure the current time in a 12-hour format with a simple click on the clock icon (‘🕐’) located in both the Start Time and End Time sections.

The primary function of this calculator is to find out how much time has passed between two different time. In this calculator, we fill the time in 12-hour clock format, which divides the day into two parts: AM (Ante Meridiem, before noon) and PM (Post Meridiem, afternoon). This calculator could be used for various purposes, such as calculating work hours, travel times, event planning, or any situation where knowing the time difference is important.

Note: This ‘Time Duration Calculator’ specifically calculates the time interval between two events with a maximum time difference of less than 24 hours.

Additionally, you can copy the result with a single click on the notebook icon (‘📋’) in the result section. & For a fresh start with the calculator, you can simply press the clear button.

## Step-By-Step Guide To Using ‘Time Duration Calculator’

1. Set Start Time

To use the current time as the start time, simply click the clock icon (‘🕐’).

If you wish to enter a custom start time manually:

• In the “Hours” field, input the hours (e.g., 2).
• In the “Minutes” field, input the minutes (e.g., 30).
• In the “Seconds” field, input the seconds (e.g., 15).
• Select “AM” or “PM” as appropriate.

2. Set End Time
Follow the same process as in the previous step to set the end time.

3. Calculate the Time Duration
After entering the time components, click the “Calculate” button. This will compute and display the time duration in four different formats: HH:MM:SS, Hours only, Minutes only, and Seconds only.

4. Copy the Result
To copy the calculated time duration for further use, click on the notebook icon (‘📋’) next to the result format you want to copy. This will copy the result to your clipboard, allowing you to paste it elsewhere.

5. Clear the Fields
To start over or enter a different time, click the “Clear” button. This will reset all input fields and result values to zero.

## How to Calculating Time Duration Manual

In our ‘time duration calculator,’ you can calculate time duration between two times in four different formats: hh:mm:ss format, hours only, minutes only, or seconds only. However, during the process, I will only display time differences in the hh:mm:ss format. To learn how to convert hh:mm:ss format into hours only, minutes only, or seconds only, please refer to my post titled ‘Time To Decimal Calculator.’

Example 1. To calculate the time difference between 12:51:55 AM and 9:17:22 PM, you can follow these steps: Step 1: Convert both times to a 24-hour format (hh:mm:ss) using the following rules:

• If the time is in AM and the hour (hh) is 12, then the new hour (hh) becomes old hour (hh) – 12.
• If the time is in PM and the hour (hh) is less than 12, then the new hour (hh) becomes old hour (hh) + 12.

Start Time: 12:51:55 AM becomes 00:51:55.
End Time: 9:17:22 PM becomes 21:17:22.

Step 2: Calculate the time difference by subtracting the start time from the end time. 21:17:22 – 00:51:55
Step 3: Perform the subtraction for each component (First seconds, Second minutes, and Third hours).
For seconds: 22 – 55 = -33. Since the seconds are negative, carry 1 minute.
22 seconds + 1 minute – 55 seconds = 22 + 60 – 55 = 27 seconds.

For minutes: (17 – 1) – 51 = -35. Since the minutes are negative, carry 1 hour (60 minutes).
(16 + 60) – 51 = 25 minutes.

For hours: (21 – 1) – 0 = 20 hours.
So, the time difference between 12:51:55 AM and 9:17:22 PM is 20 hours, 25 minutes, and 27 seconds.

Now To learn how to convert 20 hours, 25 minutes, and 27 seconds into hours, minutes, or seconds individually, please refer to my article titled “Time To Decimal Calculator.”

Example 2. To calculate the time difference between 1:45:23 PM and 3:55:11 AM.  you can follow these steps:

Step 1: Convert both times to a 24-hour format (hh:mm:ss) using the following rules:

• If the time is in AM and the hour (hh) is 12, then the new hour (hh) becomes old hour (hh) – 12.
• If the time is in PM and the hour (hh) is less than 12, then the new hour (hh) becomes old hour (hh) + 12.

Start Time: 1:45:23 PM becomes 13:45:23.
End Time: 3:55:11 AM remains same 3:55:11.

Step 2: Calculate the time difference by subtracting the start time from the end time. 13:45:23 – 3:55:11
Step 3: Perform the subtraction for each component (First seconds, Second minutes, and Third hours).
For seconds: 11 – 23 = -ve. Since the seconds are negative, carry 1 minute.
11 seconds + 1 minute – 23 seconds = 11 + 60 – 23 = 48 seconds.

For minutes: (55- 1) – 45 = 9 minutes.

For hours: 3 – 13 = -ve. Since the hours are negative, carry 1 day.
3 hours + 24 hours – 13 hours =14 Hours.
So, the time difference between 1:45:23 PM and 3:55:11 AM is: 14 hours, 9 minutes, and 48 seconds.

Now To learn how to convert 14 hours, 9 minutes, and 48 seconds into hours, minutes, or seconds individually, please refer to my article titled “Time To Decimal Calculator.”
