Yes please! Especially if it can incorporate tasks as well! I'm migrating away from google as much as I can. Using Soverin.net now as server for email, calendar and tasks. On my desktop/laptop I use Thunderbird as the client, but on mobile it's still a lot more complicated (calendar app, thunderbird mobile, tasks.org, davx5; quite complicated)
The lack of calendar on mobile is the only reason I'm still using Outlook on my phone. I'm limited on client choice do to my job. So I'm left with Gmail, Outlook, or Thunderbird. But I need calendar support on mobile as my daily calendar changes by the hour.
I would love to have a Thunderbird Calendar on my Android phone that would synchronise directly with the thunderbird calendar on my Windows Laptop without using Google. At the moment my calendar data is scattered among several calendar apps that I have tried, but did not do the job and it becoming very confusing.
Yes. This is exactly why I am here this evening. I want to avoid using the normal online calendars, and use the same calendar as on my desktop and laptop computers. One of the suggestions by Mozilla is to use one of the 'many calendars' on Google Play, but I am reluctant to do so. I prefer to have an integrated system, across platforms.
Ever since the death of Lotus/IBM Smartsuite, and thus the IBM/Lotus (formerly Threadz) Organizer, I have witnessed gradual loss of functionality, and the Thunderbird calendar is the next best calendar.
