Calculate Your Age in Days - Power Automate Desktop Flow

Calculate Your Age in Days - Power Automate Desktop Flow

This flow asks the user to select their birth date and then calculates how many days they have lived so far. Finally, it shows the result in a motivational message.

Step-by-Step Explanation

  1. Show flow description
    The flow begins by displaying a message box explaining what the automation does: it will ask for your birth date and compute your age in total number of days.
  2. Prompt user to select their birth date
    A date selection dialog appears where the user picks their birthday. The selected date is saved in the variable BirthDate.
  3. Get the current date
    The flow retrieves today’s date (without time) and stores it in CurrentDate.
  4. Calculate the difference in days
    Using the DateTime.Subtract action, the flow subtracts the birth date from today's date. The result—total days alive—is stored in DaysAlive.
  5. Show the age in days with a motivational message
    A final message displays the number of days the user has lived so far, along with an encouraging note reminding them to make every day count.
