Calendar integration (Google Calendar, etc.)

[FranciscoKnebel]

Hello, I've been trying out the platform recently. Adding this here as I didn't find any discussions about it.
One big feature that other time-trackers have is a 'calendar' view, which we can filter ('current week', 'last week', 'today', 'yesterday').

Instead of just a table with entries, showing views like 'Current Work Week', with all the entries and allowing to move around entries, updating date/time.

Another helpful thing related to this is sync with Google Calendar, allowing for quick adding entries based on saved events from the calendar, showing as suggestions in the 'calendar' view.

Both these things are details we've seen that would be great inclusions to the workflow using the app.

Thank you for the Suggestions. There is a Discussion for Calendar Views here: #267 but there is none for Integrations into Calendar Services yet, so I'll happily convert this into a discussion for Calendar Integrations, as we handle feature requests in discussions (so people can upvote them).

I'd love a Google Calendar and iCal import / sync feature, especially for scheduled tasks like meetings.

Connecting to an app like cal.com would also be fantastic!

I second that, google calendar integration would be really helpful for tracking planned meetings. It would greatly improve our workflow and reduce time for manual entries.

We needed this internally, so we built it in a fork and have been running it in production for a bit. Happy to upstream it if you're interested.

What it does:

• Connect a Google account per user from the profile settings page, OAuth via Socialite, tokens stored in a google_calendar_connections table with refresh handling
• Read-only scope (calendar.events.readonly) — we never write back to the calendar
• Events for the visible range show up as greyed-out background entries in the calendar view, alongside real time entries
• Click one and it opens the create-entry modal prefilled with the event title and start/end, so tracking a meeting you already had is one click

Roughly 1400 lines excluding tests, plus PHPUnit coverage for the endpoints and the service. New model + two migrations, one new controller for the OAuth dance, one API endpoint for fetching events, and some additions to the existing calendar components.

Before I put in the work to rebase and open a PR: is a calendar sync something you want in core at all, or is this the kind of thing you'd rather keep for the extension system? Also happy to cut it down or restructure it if the shape doesn't fit what you have in mind. Just don't want to drop 1400 lines on you unannounced.
