Calculating age from birth date and current date using Workflow Definition Language expressions

If I have a date of birth (from a Microsoft form question) and have inserted it into an Excel table row, how would I calculate age using a Workflow Definition Expression which would be placed in an Excel table column beside the one for date of birth?

Re: Calculating age from birth date and current date using Workflow Definition Language expressions

I did manage to get age using ticks for the birthdate (from Microsoft Form field) and utcNow.  After dividing by a couple of constants I was able to get age as a float.

 
Expression is:  div(div(sub(variables('Today'),variables('Birthdate')),864000000000),365.25)
 
Variable Today is "ticks(utcNow())"
 
Variable Birthdate is "
ticks(body('Get_response_details')?['rde329303c5a04b32b9b9f35a0564400e']) based on Microsoft Form response field.
 
At the end of the day I did not go ahead with the calculation as the result is not dynamic, i.e. result does not change if someone has a birthday.

Re: Calculating age from birth date and current date using Workflow Definition Language expressions

Hi @ras1000,

 

Currently it is not possible to use a datediff function in flow to count days between two days. There is a similar request on Flow Ideas Forum, please vote the idea at here:
