Lists Formulas For Calculate Age From Date of Birth
Hi,
In the below list I have a column labeled 'DoB (Date of Birth)' and another column labeled 'Age". How do I make the calculated age based on the date of birth automatically populate the 'age' field?
Thanks

jinibob You can do this with JSON column formatting. I tested this solution by RobElliott and it worked perfectly. Date calculation on SharePoint lists between today and a birthdate - Microsoft Tech Community
{ "$schema": "https://developer.microsoft.com/json-schemas/sp/column-formatting.schema.json", "elmType": "div", "txtContent": "=floor((Number(@now)-Number([$DoB]))/(1000*60*60*24*12)/365*12)" }- Hi,
Thanks for the info. Where do I need to paste the above code that you have kindly provided?
Thanksjinibob Addition to above all responses, Here's Microsoft official documentation on this topic which might help you:
Use column formatting to customize SharePoint
Note: column (JSON) formatting only customizes display of list view to show the formatted value. It does not store/save actual value in column. So, you will not be able to apply sort/filter based on these values in list view.
