Calendar support on Thunderbird mobile

[SamBouwer]

It would be great if Thunderbird mobile supports calendars like the desktop applications supports calendars.

Perhaps it is a crazy idea, but why not bringing back the old Sunbird as a calendar app for mobile devices?

It would be nice to have an agenda on Thunderbird for Android

Such a great idea, I'm trying to de-google my life and I think that would be good

Having calendar would be awesome. More than that, I'd say it is necessary.

Update - in the mobile plan for 2026, not yet released, we plan to do some exploration of this idea.  So there may not be code released, but there will be an evaluation.

It would be nice if it would be a separate app rather than part of Thunderbird Mobile. Even better, Lightning name could have a return in this form as Thunderbird Lightning as a dedicated mobile calendar app.

Same, would really use an integration of the desktop calendar, it would allow to fully replace outlook in that regard

[Yoseph]

I got sick of using outlook on my mobile especially after the ADD been added. though, I switched to my favorite thunderbird as I am a long time user on Desktops. I was realy surprised that there is no Calender. I am glad to see many request here, and hope to see one if not better than outlook then at least equivalent. 

Thanks team, your work has been appreciated for years!

a huge win if it can be shipped. I need it too!

Is Thunderbird also capable of registering on Eurostack, or not without a complex restructure? That would also be a great win.

We at Natural Capital AI (www.naturalcapitalai.com, open source github set for release next month) would love to also help with an energy management MCP for the calendar function - the commercial ones are.. mad.

Love and go Thunderbird.
