Time Duration Calculator On The Clock

















Introduction

Calculating durations between specific times is a common requirement in various activities, from scheduling events to tracking work hours. The Time Duration Calculator presented here operates on a 12-hour clock system, allowing users to accurately determine the duration between two selected times. This tool is especially handy for tasks where time intervals are crucial.

Formula

The calculator employs a 12-hour clock format, considering both the hours and minutes, as well as the AM/PM designation. It calculates the difference between the start and end times, taking into account the AM and PM selections. The result is displayed as hours and minutes.

How to Use

  1. Enter the starting hour in the “Start Hour” field (1-12).
  2. Enter the starting minute in the “Start Minute” field (0-59).
  3. Select AM or PM in the “AM/PM” dropdown for the start time.
  4. Enter the ending hour in the “End Hour” field (1-12).
  5. Enter the ending minute in the “End Minute” field (0-59).
  6. Select AM or PM in the “AM/PM” dropdown for the end time.
  7. Click the “Calculate” button.
  8. The calculated duration will be displayed in the “Duration” field.

Example

Suppose you want to find the duration between 3:30 PM and 8:45 AM. Enter “3” in the “Start Hour,” “30” in the “Start Minute,” select “PM” for “AM/PM,” enter “8” in the “End Hour,” “45” in the “End Minute,” and select “AM” for “AM/PM.” Click “Calculate,” and the calculator will display a duration of 05:15 (5 hours and 15 minutes).
