Online Calendar Software

I'm looking for some online calendar software, which uses CalDAV.

I currently use TheGood.Cloud (a public NextCloud instance), but it's unencrypted and a tad slow where I am. I also used to use fruux.

For to-do lists, I currently use Todo.txt, but I am moving to Vikunja.

Is there anything out there?

I'd also like to make it clear that I AM IN NO POSITION TO SELF-HOST. At least, I won't be for a long time.

Thanks!

Mailbox.org. You can connect via CalDav to your calendar there.

- I'm not OP but also looking for a calendar. Would this allow me to share a calendar of events publicly with whoever has a link? A lot of people can't see my google calendar if they don't have a Gmail account, which is annoying.

  I just checked and yes. When you use the link, it puts you in like a guest account to view the calendar.

- I second that, been using mailbox for the past 6 months and it works like a charm. You also have a todo tool on mailbox that I think synchronizes via Caldav too, but I don't use it so I don't know how it compares to todo.txt

  It does, yes. I use the tasks.org app to manage.

I second this big time. I've been looking for some good online calendar as well that is probably protected. Long time ago I used borg calender. Simple but unfortunately only offline.

ooo. this is a good question!

not sure about free or CalDAV, but i thought that proton mail was putting in some calendar function, and eteSync also do calendar, however, it is their own protocol (i think), not calDav. check it out though, it may work with an external CalDAV server?

- My biggest problem with Proton is the price. Their family plan is $AUD800 (479 Euro) for 2 years at the cheapest price which is obscene. I can get a family plan with the likes of Microsoft (ugh) for just $260/2 years and it includes Office 365 as well.

  Yhe family plan is the price of 3 "unlimited" subscriptions, if you don't need unlimited then Mail Plus is far more reasonable at AU$140/2yrs, for one person though.
  
  I do wish they had a "Mail Plus Family" for up to 3 people, would be a good middle ground to get my family to switch.

- Proton has a nice UI and works well (I've used it for two years before moving to mailbox.org) but as of 6 months back, I was unable to make it work outside their walled garden. You can subscribe to proton calendar with any other calendar app, so you can read your calendar via caldav, but I found no way to edit it other than using their app.
  
  I would recommand Proton for a lot of reasons, but if having a caldav calendar matrers to you I don't think Proton is a good option.

- Proton recently updated their calendar to include an option to share a calendar with anyone (so they do not need a Proton account to see events).

Are you aware that you can purchase NextCloud hosting for very cheap? I think I'm paying less than $25 USD per year.

Has anyone tried tutanota? I started checking a bit and anternativeto.net recommend me this when I asked for an alternative to Google calendar. https://alternativeto.net/software/tutanota/about/ From the description sounds like it has all that's needed. I just wouldn't need the email account linked to it.

- I already use Tutanota for email, but you have to pay if you want multiple calendars.
  
  I mean, I could probably code events manually using colour emojis (🟥🟧🟨🟩🟦🟪⬛️⬜️🟫), but ideally multiple calendars would be standard.

  Does it have an option to add contacts with their birthdays?

About the calendar with CalDAV support, I always used the one that comes with my Zoho Mail free account and never had a problem with it.
To sync notes and todo.txt between devices, I use Syncthing, that is end to end encrypted and peer-to-peer, so there's no need to rely on a centalized cloud or self-host.

Otherwise you could write to the good cloud team , they can put you on another node. That happened to me , twice , and now it is much faster . I use it to manage my calendars
