Age according to DoB

[MelauriePelland]

I've tried using the following JSON formula to calculate the age according to the date of birth column but ever since I tried adding the formula to my pre-existing list, the age displays as 53. How do I fix this?

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/column-formatting.schema.json",
  "elmType": "div",
  "txtContent": "=floor((Number(@now)-Number([$Birthday]))/(1000*60*60*24*12)/365*12)"
}

@MelauriePelland sorry, I can't reproduce this; copying & pasting your JSON I get the correct results:

Make sure the Age column is a number column set to no decimal places.

@RobElliott

The age column is set as a number column with no decimal places already. I get this error message when I enter the JSON formula : $ref '/properties/attributes/class' in 'https://developer.microsoft.com/json-schemas/sp/column-formatting.schema.json' can not be resolved.(768)

Could that be the reason why it's not working for me?

@MelauriePelland If you are using SharePoint online, use below schema in your JSON: 

"$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",

Example: 

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
  "elmType": "div",
  "txtContent": "=floor((Number(@now)-Number([$Birthday]))/(1000*60*60*24*12)/365*12)"
}

@ganeshsanap You do realize you just gave me the exact same JSON I already had?

[#6]

@MelauriePelland No, look closely at the URLs. 

You were using this schema URL: 

https://developer.microsoft.com/json-schemas/sp/column-formatting.schema.json

and I am asking you to try using this URL instead: 

https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json

The first URL/schema is required for SharePoint 2019 and the v2 schema is used for SharePoint online.

Well, whether a v2 was added or not, I get the same results.

[#8]

@MelauriePelland Are you still getting error related to $ref '/properties/attributes/class' after using v2 schema?

@ganeshsanap Yes, the same error messages appears when using the v2.

@MelauriePellandI am also getting 53 as every age

[#11]

53 always 53 ... doesn't matter which json I use... frustrating

@Thomasw1964 since my earlier post in this thread I have moved tenant, so I tried it again on a new list but, sorry, I still couldn't reproduce the result of 53, everything was correct:
