 * Hello, Is there a mathematical formula to calculate the number of years between
   two dates or do I have to create a function?
   My request concerns the calculation
   of the age of a person starting from a current date field and a date of birth
   field
 * Best regards

 * Hello [@kjou06](https://wordpress.org/support/users/kjou06/)
 * Thank you so much for using our plugin.
 * The plugin includes a module specific for Date/Time operations ( [https://cff.dwbooster.com/documentation#datetime-module](https://cff.dwbooster.com/documentation#datetime-module))
 * For example, assuming the fieldname1 is the a date field to allow the users enter
   their birth date. You can insert a calculated field in the form and enter the
   equations:
 *     ```wp-block-code
       DATEDIFF(fieldname1, TODAY(), 'dd/mm/yyyy', 'y')['years']
       ```
   
 * And that’s all.
 * Best regards.
