Power Automate Desktop : Get First Working Day of the Next Month

Get First Working Day of the Next Month

This flow gets the current date and time and calculates the first working day of the following month. If the first day of the month falls on a Saturday or Sunday, the flow automatically selects Monday as the first working day.

Step-by-Step Explanation

  1. Get the current date and time
    The flow starts by retrieving the current date and time and storing it in the variable Now.
  2. Add one month to the current date
    The flow adds one month to Now and stores the result in Nowplus1. This step ensures we are working with the next month.
  3. Create the first day of next month
    The flow constructs a text value using:
    %Nowplus1.Month%/01/%Nowplus1.Year%
    This represents the 1st day of the upcoming month.
    It then converts this text into a DateTime variable called FirstDayOfNextMonth.
  4. Check the day of the week
    A message box displays the actual weekday of FirstDayOfNextMonth (e.g., Monday, Saturday, etc.).

    The flow then evaluates:
    • If it is Saturday → Add 2 days (next Monday)
    • If it is Sunday → Add 1 day (next Monday)
    • Otherwise → The first day itself is a working day
  5. Show the result
    Finally, the flow displays a message showing which weekday is the first working day of next month.
    Example: "First working day of next month is Monday"

Calling Microsoft Graph API from Power Automate Using Azure App Services – Step-by-Step Guide

Step 1: You should have an Azure subscription, or if you have access to the Microsoft Entra Admin Center, you can create an app from there. This app can then be used in Power Automate to connect to Microsoft Graph API. Step 2: Click on "New registration" , provide a name for your app, assign the required API permissions (such as Microsoft Graph permissions), and then click "Register" to complete the app registration process. Step 3: After registration, you'll be redirected to the app's overview page. From there, navigate to the API permissions tab and click "Add a permission" to assign the necessary Microsoft Graph API permissions. Step 4: Select Microsoft Graph as the API, and based on your requirements, choose the appropriate permissions. In my case, I selected Application permissions , which do not require user sign-in and are suitable for background services or automation. Step 5: Select the required Microsoft Graph API permissions.
