Average Time Calculator

Average time refers to the middle point between two or more time values. We built our average time calculator to handle both clock times and moving times to give an instant response and be exported in a CSV file.

How our average time calculator works

By default, our time calculator shows two rows of data entry but can be adjusted for as many rows as needed. We built the calculator to handle both clock times by inputing the hours and minutes like the hands of a clock & for pacing times in the same way. Data is downloaded in a csv form and compatible to be copied to gsheets if needed.

How to use it

Simply input the hours, minutes, and seconds for each time entry you want to average. Click the "Calculate Average" button to see the result. You can add more rows by clicking the "+ Add Row" button. To reset the form, click the "Reset" button. To download the data in CSV format, click the "Download CSV" button.

Cheat sheet:

  • Click the "+ Add Row" button to add more time entries.
  • Click the "Calculate Average" button to see the average time.
  • Click the "Reset" button to clear all time entries.
  • Click the "Download CSV" button to download the time entries in CSV format.

How to find average times

  • 24-hour vs. 12-hour Clock: Time can be represented in either format. Consistency is crucial.
  • Conversion to Uniform Units: Times must be converted to the same unit (minutes or seconds) for accurate computation.
  • Calculation of Cumulative Average: The sum of all time values, once converted, is divided by the number of values to find the average.
  1. Convert Times to Minutes or Seconds
  2. Make your times standard. Whether this is for clock times or a timer, I'd recommend using the same number unit to make your calculation much easier.

  3. Sum All Converted Times
  4. Once you have your times in the same unit, add them together. This is why we need everything in the same unit.

  5. Divide by the Number of Time Values
  6. Divide the total sum by the number of values to find the average time. For example, if you've averaged four different times to minutes and found the sum, divide your total minutes by four.

  7. Convert the Average Back to Time Format
  8. Convert the average time back into a standard time format. This can be clock time or hours/minutes. We want to covert with consistency back to the original format.

When to Average Time

Averaging hours and minutes

Objective: Find the average time between 2:15 PM and 4:45 PM.

  • Convert to Minutes: Convert 2:15 PM to 135 minutes (2 hours * 60 + 15 minutes) and 4:45 PM to 285 minutes (4 hours * 60 + 45 minutes).
  • Calculate Total Minutes: Add the minutes together (135 + 285 = 420 minutes).
  • Find the Average: Divide the total minutes by 2 to find the average (420 / 2 = 210 minutes).
  • Convert Back to Time Format: Convert 210 minutes back to a standard time format to get 3 hours and 30 minutes, or 3:30 PM.

Averaging clock time

Objective: Find the average time between 11:00 PM and 2:00 AM.

  • Convert to 24-Hour Format: Convert 11:00 PM to 23:00 (1380 minutes) and 2:00 AM to 2:00 (120 minutes).
  • Calculate Total Minutes: Add the minutes together (1380 + 120 = 1500 minutes).
  • Find the Average: Divide the total minutes by 2 to find the average (1500 / 2 = 750 minutes).
  • Convert Back to Time Format: Convert 750 minutes back to a standard time format to get 12:30 AM.
