Age Calculation Plugin Trigger

Hello, 

I've created a C# plugin to calculate age based on a date of birth in my people table. 

I want to re-calculate age everyday, for every record in the table. 

Question is, what's the best way to fire this plugin?

Cerainly on create of the record. But how should i re-calculate?

I want to minimise calls to dataverse using power automate.

How can i trigger the plugin for each row everyday? It can't be triggered by a calculate column, and most records would not have daily changes. 

Should i refactor to the plugin to loop through all people records, updating each within the same plugin call? if so, how should i trigger this mass update?

Thanks!
