Totally agree. Simple first. Get it working, then add the complicated age breakdown later if people actually ask for it.

Honestly, just showing the birthday on the date itself is underrated. I do the same thing for keeping my brain sharp — nothing fancy. One trivia question every morning. That's it.

I use https://dailytriviaquestions.com because it's exactly that: simple. New question daily. Guess. See the answer. Done in 30 seconds.

Same philosophy as your birthday idea — small, consistent, actually useful. No fluff.

Hope you get that shipped. Simple stuff is usually what people end up loving most.

What would be even more useful than the birthday date is a reminder at say two weeks beforehand. This means one could send a card, a present or even schedule a call on the actual date.

This would be a good start to making Proton a more fun/personable experience.

Good and simple feature, duplicate of https://protonmail.uservoice.com/forums/932842-proton-calendar/suggestions/42258667-contact-birthdays-appear-on-calendar

I would definitely want an option to also NOT show specific birthdays, even if they are in the contact details.
