Nextcloud, CalDAV, Thunderbird.

Radicale + client (Thunderbird on desktop, fossify calendar on phone)

I use Nextcloud. Of course that only makes sense when you use the other Nextcloud stuff as well.

Radicale on my server and davx5 on my android to sync contacts and calendar.

I host a CalDAV server (specifically Nextcloud's Calendar app, though plenty of others exist, like Radicale) and all my devices sync with it.

Private I use Nextcloud + Betterbird (Thunderbird Softfork (stays compatible with the matching esr version)) + DAVx5 for Android.

At work we use an old web calendar in php5, as this is the only calendar we found that has a side by side view. Each coworker has his own calendar and in the 4 week view, each is displayed side by side. We didn't found any replacement with that kind of view. Also we use the categories very strict. Each entry need a category, the admin defines the categories and it shows icons for it. Nextcloud even introduced categories a few years ago and still doesn't have the option to define ones and delete default ones. You can add own categories on the fly, but this is so bad in design, as everyone needs discipline, which doesn't happen.

I have a paper calendar on my wall. It's really nice because I find writing things down helps me remember, and also because you can get ones with different pictures or jokes or facts or recipes on the other side, so you get a new set each month.

Also if you follow two calendar systems it's particularly nice because they can both be on the same calendar. (For example mine is a combined hebrew gregorian calendar, which is much nicer than just having the computer tell me when holidays are)

We use Nextcloud. (It's honestly about the only thing we use Nextcloud for.) For adding events and checking stuff we just use the web UI; it's also synced to Kalendar/Merkuro Calendar on our desktop and we get calendar notifications that way.

I have a paper 4 year calendar hanging on the wall. Takes a while to write in all the dates and holidays. With liquid paper/white out I have been using the same calendar for well over 10 years.

On my phone - Fossify Calendar.

We use Home Assistant. My wife wants to have as few apps as possible on her phone, so this way we can use the calendar and Mealie all in one app

The self hosted calendar solutions have rubbish web apps, unfortunately. I'm pretty sure Radicale still doesn't let you search your entire calendar for entries.

Obviously most calendar apps on desktop and your phone will have that feature, but that's not exactly useful when you're on a device you don't manage and just wanna check your calendar real quick.

I've been playing with calcurse and calcure, both TUI calendars because I can't keep something like Thunderbird open on my cruddy low RAM laptop. There are some sync methods but they're pretty janky. I'm tempted to just set up a plaintext file with appointments and have a script scan for the upcoming 24 hours for notifications or something
