Hello from New York City!

Is it possible to share a calendar event. When right clicking an event brings up a pop-up menu but a command to share the event does not exist.

Similar calendar event sharing functionality exists in other web based calendar software.

From an avid user on Win11x64 with Thunderbird 115.7.0 (64-bit).

Any clues appreciated. Thank you.

Wenn ich den Wochenkalender ausdrucke erscheint nie der Wochentag (Montag, Dienstag usw.), obwohl diese auf dem Bildschirm in der Wochenansicht zu sehen sind. Leider finde ich keine Möglichkeit, dies zu ändern. Können sie mir weiterhelfen? Mit freundlichen Grüßen Gerhard

I was wondering if there's a way to include more than just 4 weeks worth of events/task in the calendar sidebar? I have increased it from 2 weeks to 4 weeks but I would like to see more without going directly into the Calendar. Thank you,

Google Calendar on iphone - I want to have it available on Thunderbird on my PC. Advice please. Can't seem to find any comprehensible instructions.

Running Thunderbird 115.6.1 (64-bit) on Windows 10. I can add an EVENT to any of my 5 calendars in the dropdown. But when I try to add a TASK, only 4 calendars are offered. Naturally, it's the missing calendar (xxx@gmail.com) I need!

Suggestions would be deeply appreciated.

Thanks, Jeff

For many years I have been printing each month with all dated information. I use that info to manage my life and meetings. The new version 115.3.3 (64 bit) will not allow me to print a month. What do I have to do to print what I need?

Hi, I'm trying to figure out what is the correct procedure (if any) for migrating calendar/task data between different profiles WITHOUT using the UI (since upgrading to version 115, Thunderbird's UI became irresponsive when started with my existing profile , so I'm no longer be able to access my data nor to trigger the export procedure via the UI.

Can anyone point me to the right direction?

Thanks in advance for any answer.

Hello I am having issues with my calendar option not retaining the events that I have entered. I have never had this issue before. I have no clue how to get it to retain the entered events. Any direction would be greatly appreciated. Thank you! Monique

I use Calendly.com for scheduling my meetings. I'll receive a meeting confirmation email when someone books, and linked from that email is an .ics file I can import to Thunderbird calendar. This all works fine except that meetings imported don't respect the default reminder setting. No reminder is set at all for these meetings - I have to edit each event manually to append the reminder to match what I have saved in the Reminder Defaults section of Settings (15 mins).

Meetings added to my calendar in other ways (i.e. an invitation direct to my inbox) respect and apply the 15min default. This places the blame on Calendly so I looked at the .ics files I'm getting from there and find no TRIGGER reference at all. I imported an unrelated sample .ics file with the TRIGGER explicitly defined and this works, but in the absence of a TRIGGER reference in the Calendly files, my expectation is that the default reminder time would be applied.

Any advice on what may be happening?

Thanks

I recently updated to Thunderbird 115.6.0 on Linux. After doing so I can no longer add events to my calendar. In the error console I get the message, "An error occurred when writing to the calendar ... Could not find definition for Eastern Standard Time". This seems like a rather odd error. How do I fix it?

In every version from 118 beta to the latest, the Calendar View Events filter option is limited to max 1 year. In previous versions, there was a filter option to view All events. I need this option in filter to be re-instated because 1 year is not enough. I want to see all events to manage my calendar more effectively.

Specific 'Calendar' topic, but could also be considered to be about updating (improving) the Thunderbird controls/options/addons.

Is this a Feature Request, per say? If so, is it in the right place here? If not, where to put this?

Platform: Windows 10. Issue: Thunderbird (Lightning/Calendar) keeps aggressively stealing focus, i.e. putting the Reminder window on top of whatever else I am doing. This is incredibly annoying and unproductive. The only option is to completely disable Reminders, which defeats the purpose of course. See also, for example, https://www.reddit.com/r/Thunderbird/comments/185c727/how_can_i_prevent_the_reminders_window_from/. Requirement: I would like to still hear the Reminder sound, and it would be great if the application also 'gets highlighted' (in orange) on the Taskbar (like many applications that have something new going on, but do not immediately push themselves to the foreground) to get a visual Notification, as well.

In any case, this overly dominant behaviour of the application should NOT persist.

Thunderbird 115.6.0 (64-Bit) is no longer syncing with Google Calendar.

I do not know since when, but recently added dates in Google Calendar are not show in Thunderbird calendar and vice versa. 

I've tried to setup new connection between Thunderbird and Google, this seems to work, because I got question on smartphone (authenticator app) to allow new connection. But the dates are still not synced. Even forcing sync does not do anything. Same things happens on two Windows 10 64bit computers, but also on Linux Mint. Any advice? Thanks.

if I schedule a meeting locally for 9am some attendees receive the meeting scheduled at 8am (1 hour earlier than actual). I have checked my thunderbird date and time settings and they are correct. The attendees claim their settings are correct but between the 2 systems (Thunderbird and Outlook) there is an hour discrepancy. This is causing clients to miss my meetings. Please assist.

I installed the beta version of Thunderbird without realizing it's incredibly difficult to switch back to stable, so I'm stuck with beta. In beta, can someone explain the reasoning to me behind why calendar shows a view-only window when double clicking an event title instead of going directly to the editing window? It was so much easier to edit events before:

double click the title > start editing

Now, in beta, both ways to edit an event require extra steps:

right click title > click edit > scale the window larger > start editing or

double click title > scale the window larger > click edit > scale the window larger again > start editing.

It doesn't make any sense. I can't think of any reason for having two separate window states for an event - you don't need a display view and an edit view, because they both display the same information. Just have it open directly into the edit view like it used to.

I made a video to attach but it doesn't allow videos. Let me know if I can provide something else instead.

I used to have 3 calendars. now everything shows in one calendar named 'calendar'. how do I get to display one calendar at a time. In the current display under column 'calendar, name' I see 3 different names and the items in the display are pink, green, and yellow. I think at some time I hit 'synchronize' by mistake.

Thanks for your help.

Hi,

I have several individuals stored in my Contacts for whom I've loaded their birthdates. I would like to receive reminders and/notifications in Thunderbird when these birthdates are approaching, say like 10 days out. Is there a way to configure Contacts and/or Calendar to get these reminders/notifications in advance of these birthdates? If so, how?

thanks, Tom

I'm not sure exactly when it happened, but pretty recently, my calendar started showing 6 weeks (in 6 rows) instead of less (I think it was 4).

How do I show less weeks at once (so more of each day's pane is bigger and shows more of itself), like it used to be?

I have Thunderbird for Mac v 115.6.0

Thanks, Ted

This is probably not the best place to ask. But I would like to know how thunderbird parses icalendars. Is there is place I can see this file?

I am working on a project that uses [https://sabre.io/baikal/] Baikal

You can do a call that gets the icalendar properties but I am having trouble finding a library that can handle this. I have looked into two:

This is probably old but kind of works, however fails with malformed bad ics calendar properties link text

This one looks a little more complicated, and I think this is from some folks at thunderbird working the calendar from what I read. however fails with malformed bad ics calendar properties link text

What I do not get, is that the same ics for instance I am testing that is malformed, Thunderbird reads it like a champ and it is in my calendar. But when I try it in my own APP project, I can't get these front end libs to read it properly.

anyways, if anyone has some info on how the folks at thunderbird parse shared calendars I would love to read up on that lead.

Thanks! happy holidays!

In setting up a new phone, using BirdieSync to synchronize Thunderbird Calendar with the phone, Calendar ended up with duplicate events, but only those that had originally be setup using the "Repeat" button in the "New Event" window. (Ex. a class that meets the same time, same day, each week.)

I cannot find any way to locate and batch delete the duplicates. This seems like it should be basic functionality for a digital calendar. Is it really missing from Thunderbird or am I missing some obscurely located "Delete Duplicates" menu item?
