Create customer birthday calendar view


I added 1 custom field birthdate to customer doctype and I create a calendar view in this doctype base on birthdate field.
How can I make the birthday event repeat?


@Pheakdey_Tes1 do you mean every year at the same day ?

Yes exactly what I wanted.
I have checked in Event Calendar, it has option to repeat event yearly. but in calendar view for doctype doesn’t have.
