Come on guys.... you can do this! :-)

When adding this, please also add importing birthdays from Google. Atm bitthdays from Google Contacts are just ignored, when importing contacts into Proton.

Agreed — this is a basic feature that shouldn't still be missing. I've got hundreds of contacts imported with birthdays already filled in, and none of it shows up in the calendar. Right now I have to manually recreate every single one as a recurring event, which defeats the whole purpose of storing the date in Contacts in the first place.

While I'm at it, a few other things feel critical too: event colors (right now everything blends together, and colors are one of the main ways I visually scan a busy week), some basic display settings — a compact mode, and smaller/adjustable event labels, since right now the text is so large that most events only show a couple of letters before getting cut off — and multi-day events, which are still shown as separate entries instead of one continuous bar across the days, making anything longer than a single day hard to read at a glance.

Beyond the calendar itself, the lack of CardDAV support for Contacts is a much bigger blocker for me. Without it, I can't get a real two-way sync between Proton Contacts and the other apps and devices I actually use day to day, which makes it impossible to keep one consolidated, editable address book — and that's a big part of why birthdays never make it into the calendar in the first place.

Like others here, these are close to blockers for making the whole Proton suite my daily driver, not just Calendar. I'm genuinely happy to become a paying Proton subscriber and support what you're building — I'd jump on it as soon as these points are addressed.

Honestly, I really like Proton but calendar app is really subpar, I'm tired of waiting a basic feature like this; I'll uninstall Calendar till the app gets an updated.

Yes, this would be very nice to see in the calendar

This is pretty much a requirement to be able to use the calendar at all. I'm switching to proton calendar and I already missed a birthday of an acquaintance. Please prioritize. Can't be that this takes 6 years to implement!

if i want to keep with proton suite this is a minimum requirement

Can that be promoted?
If not possible, why having the field in contact?

Should be simple to add and not intrusive or harmful for security

Very important feature for me to start using the Proton Calendar!

This feature is crucial for me to start using the Proton Calendar.

It would be great if this included an optional feature to show how old the contact will become in order to stay aware of the possible significance of a birthday like when someone turns 30, 70 etc.

It's a nonsense to have fields on contacts with birthday or anniversary dates and don't have it on the calendar to remember it.

And a feature that have all the calendars apps.

I just discovered this feature on Google Calendar. It'd be great to see this implemented on Proton Calendar soon, too, along with the ability to edit contacts from within the Proton Mail mobile app.

I can't believe this is open since 2022 and its one of the top 5 most voted feature.

I'm a paying Proton Unlimited subscriber and recently migrated fully from Gmail. This is the single most noticeable missing feature in my daily workflow. The birthday field exists in Contacts – the Calendar integration is just not implemented. Every other major mail/calendar provider (Apple, Fastmail) has had this for years. This request has 1,800+ votes and has been "under review" since 2022. Please prioritize this – it's a basic quality-of-life feature, not a niche request.

Pls add this feature. Birthdays and other anniversaries to be shown in Calendar will be sooo valuable.

This feature is very important. Please expedite this feature release.

Apparently this idea has been waiting developement for over 5 years and has many user votes. If you really listen to us users this would be a top priority!

Hello, this feature is very very important to me!

J'ai importé tous mes contacts dans le but de pouvoir avoir automatiquement leurs anniversaires ajoutés... J'espère que vous le ferez c'est une fonction que j'utilisais beaucoup sur l'agenda Google
