how to show contacts birthday date without year

Hi,

I'm used to sync my Google contacts with my iPhone (IOS 16.3).

Googling around, it seems that IOS wants a year to show up the birthdy date in the iPhone Contacts. It seems a feature.

Otherway, if I set a birthday with dd/mm on the iPhone, it does updates contacts in Google, but still not showing the birthday date.

Google does accept birthdays without year and remind it to me in the iPhone Calendar, so not a big issue.

But, still I would like to see the birthday of my contacts on the iPhone.

Provided that it's normal/polite/whatever or siply happens that you don't know the exact year of birth of a contact, there is a work around to show a birthday without a year in iPhone? obviously without setting a dummy date
