Believe it or not, I had a similar question just today.

However, what I want is to add tasks to todo.txt and somehow see them in my calendar (as events or as a task list, my calendar app supports task lists as well as calendars). I was thinking of a way to turn my tasks from todo.txt to calendar events or something and I guess a script on a server (I have a server and use it to sync stuff like notes and files) could watch for changes, parse them and add servers to Google calendar.

Anyway, it's a slightly different question, and I can't answer your question.

Maybe there's a python library to work with Google keep notes, and you too could sync your todo.txt with your server (using syncthing) and watch file for changes, parse them and send them to Google keep using some API. I'm not sure if it's possible but you could try searching in that direction.

I also used to have a bunch of stuff in Google Tasks. Not sure how helpful what I say is gonna be but maybe it helps someone.

Google Tasks used to be its own thing, a to do/notes type of organizer which had its own Android app and web app.

Then some things happened:

• Google came out with Keep which is also a notes app but organized slightly differently.
• The Tasks web app was rolled into Gmail and became the "email tasks" thing in there.
• Google came up with this thing called "reminders" which were sort of like CalDAV tasks but not really, because only their own Calendar app was allowed to manage them (even though other calendar apps were allowed to manage Google events, just not reminders).
• Then they changed their mind and said "reminders are tasks" and last time I checked they had merged them into Tasks and they showed up both in Calendar as reminders (well "tasks" now) and in Tasks in a special list called "My Tasks".

Personally I've switched from Google Calendar to a self-hosted CalDAV and the events and tasks there are proper CalDAV events and tasks now.

As for the Googlish "Tasks" I've done a Takeout and converted the Tasks.json lists to Org Mode markdown. Org Mode is a widely supported format for notes/to-do and there are lots of apps (it's also Markdown so you can simply edit with a text editor and sync with whatever method you want). On Android I'm using the Orgzly Revived app.

I've also considered using CalDAV journals for this but there's almost zero support for them out there. DAVx5 can sync them and there's exactly one Android app (jtx Board) which I don't vibe with unfortunately (the interface rubs me in all the wrong ways). I hear Thunderbird is considering adding journal support though so that's nice of it happens.

I don't know why CalDAV journals (and CalDAV in general) isn't more widely used. Finding CalDAV web apps is a chore too, there's again like only one app that supports events, tasks and contacts (InfCloud).

Anyway that's my saga, hope it helps someone.

I'm afraid you can't

The calendar shares information due to CalDav compatibility, however I don't think it applies to Tasks as well, since we don't even know what protocol Google Tasks uses

I think the best you can do is use the Todo.txt app on your phone and sync it through Google Drive to have access in both your phone and your PC

Real homies use obsidian amd syncthing
