Go to Office 365 → Microsoft Flow

  • After this you will be redirected to below screen, Please select Organization Name (Your CRM Organization) and Entity name (In this case we considered Contact entity)
  • After this, you need to add condition to check if Birthdate field is Empty or not to proceed.Below is fetch expression to validate the same.@empty(triggerBody()?[‘birthdate’])
  • We need to add an Action to update the record and calculate Age field value in a number of* years using from expression.To update record use highlighted action as shown in below screenshot:

After this you need to select Organization Name and Entity Name once again. Here we need to select one more field i.e. Record Identifier to uniquely identify the record which needs to be updated.

Follow below screenshot to set the Record Identifier, here we select Contact:

Click on ‘Show Advanced option’ as shown in below screenshot, to populate value of Age field:

Find Age field in list then click on “Add dynamic content” then add mentioned expression as below under “Expression” tab then click OK.

int(split(string(div(div(sub(ticks(utcNow()),ticks(triggerBody()?[‘birthdate’])),864000000000),365.25)),’.’)[0])

    This will not calculate the correct age all the time. The age calculation will only be correct if utcNow() has passed the birth date for the given year ex) January 1, 1975 – June 18, 2019 = 44 years. If utcNow() is prior to the birth date for the given year, it will be inaccurate ex) September 1, 1975 – June 18, 2019 = 44 years per calculation, but should be 43 years.

      Hi,

      I have updated the blog which will resolve the issue specified in the below comment.

      Earlier I used to subtract Birth Year from Current Year however, in the updated blog I started calculating differences between Current Date and Birthdate and converted that result in Years.

      Suppose,
      Current Date = 20 June 2019
      Birthdate = 25 June 1990
      Difference in day = 10587 (i.e. 28 Years)

      Let me know if you have any further queries.

      Thanks!
