Great! - but I'm missing this functionality for iOS and iPadOS

Great! 😊

I just want to check, it says that this feature is now available for the web, but I am not sure that I understand how to do it. The help file also does not explain it. Is this actually already available? https://proton.me/support/calendar/using-calendar/manage-events

Small thing appaently, but will definitely be an improvement ! Life's made of routines, after all...))

YAY!!!!!

Duplicating on Mac App is possible, in mobile Version of IOS not can this be changed ?

Duplicating calendar events is a huge time saver for me. I chose to move my calendar to Proton only after I was sure that this feature was added, and I was disappointed to discover it was only added to the web app. I will have to find another secure calendar unless this feature comes to the Android/mobile apps soon

I would like to add a more specific detail to how this experience should work.
Apple Calendar, and many design-oriented apps like Sketch, Figma, Excalidraw etc.) allow a user to copy an object by option+dragging an event on MacOS. This is incredibly useful and I hope that this hotkey is included.

Thank you - would be occasionally useful to me.
More important would be, to be able to use Calendar in Landscape on my tablet.

Glad this is on the web app!

Good to know, thank you. It took you 3.5 years to deploy it - amazing.
What about Search on Android?

This seems like a small addition but it's a huge time saver. Please add this to the mobile apps!

Now that finally colors of the events can be chosen and night shift can be correctly visualized this feature is the missing part to complete 100% migration from Digical

To streamline using calendar, duplication of event is a must expectedly! Copy and paste an event at a day in week view, or paste to multiple days in calendar month view.

I would prefer to have a list of templated events when clicking on a date. For example, clicking on April 12 would show a list of templates to insert like Doctor, Dentist, Vacation, etc. That way I can control what's in the template (a separate view to create and edit templates) and then just need to click the date to add the event.

This feature is a game changer, now the usability of the callendar for recurring events that doesn`t has the same schedule is a big pain.

More than 3 years later and the Android app doesn't support yet the simple duplicate feature...!

Please add this feature to iOS. And as mentioned below, Shortcuts for copy and paste would be really appreciated, either alt-drag as other suggested or ctrl+c / ctrl+v on Web browser.

Adding my support for the duplicate function within the Android app! This is an important feature to me

In Proton Calendar in Android we cannot copy an existing event as we can from the web browser. Some recurring events like doctor's appointments, friends get-togethers and others may contain a good deal of information. The ability to make a copy of that existing event and paste it to a new time and date would be extremely useful.
