Hi, When creating an event in the calendar view, I get my timezone displayed (Europe/Paris), I set my starting and ending time and save.

On event display in the calendar, I immediately notice that the time is off by 1h. On viewing the details, the right time is displayed but on 'Europe/Dublin' timezone. Changing it back doesn't fix the time, timezone always change after save.

I took a look at my settings, tried to use "use system timezone" (= Europe/Paris) of forced it to Europe/Paris, even checked the config editor, but nothing changed.

Did I miss a setting ?

My calendar is sync by CalDav (using TBSync), don't know if this could be related.

Thunderbird 115.9.0 (64-bit).

I have my timezone set to manual, Europe.

I create an event for 30 March 2024 and the time is displaying in my time zone

I mark it as ALL DAY and it switches to Local Time (not a problem so far)

If I display the calendar as 1 month starting with 24 March, then the event shows properly on Saturday 30 March

If I scroll the calendar up to start on 31 March, now the event shows on 31 March.

If I edit the event, it says the timezone is Chicago.

Changing the timezone and resaving it doesn't help.

Whenever I enter a new calendar event in Thunderbird, the calendar always defaults the event start time to 15 minutes after the hour, regardless of what time I'm making the new calendar entry. Is the new event start time a default setting and if so, how do I change the default to start new events on the hour, meaning HH:00 and not HH:15 which is what Thunderbird always defaults to? I use Thunderbird v115.9.0 (64-bit) for Windows, and the computer runs Windows 10 Home, v22H2, build 19045.4170. Please advise. Thank you.

On my new laptop I can't get convert to task working. When I click on this option nothing happens. Convert to event works fine.

This functionality works fine on my desktop PC

Hi, I have a nextcloud setup at home on my internal network. Whenever I am away from that network, Thunderbird bombards me with error messages because it cannot sync a specific calendar (An error occurred when writing to the calendar Contact birthdays! Please see below for more information.) This is the first calendar on the list of calendars so I think it just happens to be that one that causes the error. What I would like to do is have Thunderbird detect that it isn't on my home wifi and not sync the calendars. Is this possible? Thanks!

Hello, In Thunderbird (Vers. 115.9, OS Linux Zorin OS 17) I can integrate a calendar from a Mailbox.org account as described here(https://kb.mailbox.org/de/privat/adressbuch-und-kalender/caldav-clients-outlook-thunderbird-macos-evolution-kontact/). Everything works fine. If I now want to import a 2nd calendar from another mailbox.org account, this does not work. I can go through the process normally, but the 2nd calendar is not displayed. Does anyone have the same problem? It can't be that Thunderbird is not able to integrate 2 calendars ? Many thanks for your help

The attendees I select are not receiving their invites to my calendar events. My version of Thunderbird (TB) is 115.9.0 (64-bit). I check my sent folder and it does not send. Older versions of TB, the Calendar invite worked and I can see it was sent from the sent folder. Please note that I am not tech savvy and I need a solution that an average person can employ. If someone has a solution, please get it in step by step instructions and assume I know next to nothing.

Hello! I am facing the issue with time zone translations. Here is what I do. First, I create event on web-interface of the google calendar. That account is linked to TB's calendar. This calendar has settings for my timezone as in the first screenshot, that is GMT+3 for Kyiv, Ukraine. It is actually GMT+2 + daylight saving hour in effect. Country is also set to Ukraine. Next, my Windows 11 system is set to set time and timezone automatically, region - Ukraine. It displays UTC+2 Helsinki, Kyiv,... I guess it's Windows settings display quirk, because time is correct and WSL console shows

~$ date -R Thu, 18 Apr 2024 18:59:25 +0300

My TB's calendar is set to have system's timezone as in 3rd screenshot.

Now if I see my event in TB calendar, it is placed one hour later, say 9 am event starts at 10. So reminders also come hour later. Also strange thing is that event properties in TB show correct time like 9:00 till 10:40, but for some strange timezone Europe/Zaporozhye, as in 4th picture.

However, if I set TB's calendar manually to Europe/Kiev (which should be Kyiv, but that's another story), then events are shifted hour up to their right place, 9 am. So this is my issue: when I set calendar forcibly to Kyiv timezone, it does translate it right. When I ask calendar to rely on system's timezone, which indeed is also Kyiv, then I get one hour behind.

I'm having a really annoying problem where Calendar events, even tho they have reminders/notifications properly set up, just don't actually trigger these notifications when they're supposed to.

Are there any logs or debug settings or anything I can do to troubleshoot this further? All of the direct UI settings are definitely set up correctly. And there are other events for which notifications work fine, so it's not that notifications are broken altogether

Thunderbird is is displaying 24hr in emails and calendar but the system is set not to used 24hr I'm running Linux Mint 19.3 (64-bit) Thunderbird 102.11.0 (64-bit).

Hi

I am unable to access my old calendar details after moving to google calendar. I had entries in calendar prior to dec 2016 that if possible I would like to retrieve. I backed up a copy on 070717 including email address book and calendar. I have the files on my hard drive. There is a folder called calendar-data with cache info in it but when I click on it it says to open in microsoft store? How do I access them now in Thunderbird calendar I have the latest thunderbird version 115.7.0 64bit

would appreciate your support Brad

I have a website from which I can download a calendar as an ics file which I'd like to import. Initially this works OK. However, sometimes this website calendar is amended and I'd like to be able to update my Thunderbird calendar but a subsequent import fails completely if it includes an update to an existing entry. I know that the UID of an event in the ics file matches that of an existing Thunderbird entry but the LAST-MODIFIED value is later in the second ics file entry. Is there any other condition that should be required to allow the import to run and update any matching existing entries? Any ideas welcome. CrowboroughChris

While trying to import a .ics into thunderbird calendar an error occurs:

"Beim Schreiben in den Kalender Privat ist ein Fehler aufgetreten! Weitere Informationen stehen weiter unten." "Fehlercode: MODIFICATION_FAILED" "Beschreibung: Falls diese Nachricht nach dem Verwenden von "Zurückstellen" oder "Schließen" für eine Erinnerung angezeigt wird, aber Sie für diesen Kalender keine Termine hinzufügen oder bearbeiten wollen, so können Sie diesen Kalender als schreibgeschützt markieren, um diese Mitteilung nicht mehr angezeigt zu bekommen. Klicken Sie dazu mit der rechten Maustaste auf den Kalender in der Kalenderliste der Termin- oder Aufgabenansicht und öffnen Sie die Eigenschaften."

The .ics file was generated by calendar export from Thunderbird version 115.6.0 and the import is also being done with the same TB version. OS: Linux Mint 21.3 Virginia

I can import the .ics into other calendar software without problems, so it doesn't seem to be damaged.

Thunderbird 113 (?), local calendar, Win 10, email invites stopped being sent to the listed Attendees. Correct email was entered on Calendar/Properties/Email and Notify attendees was ticked in New Event dialogue. Attendees were correctly entered under New Event/Invite Attendees but after clicking Save and Close, there was no Invitation email record in "Sent" emails and no Attendees receives email invitations. The event was correctly saved in the originator's calendar.

TB 115.7.0 installed from scratch on a new Win 11 PC and the emails/calendar data transferred from the old PC. Everything works *except* that no invitation emails are still sent to the listed Attendees of a new event (same symptoms as on the Win 10 PC). So transferring emails and calendar entries transferred the problem to the new PC.

What next?

Hi!

We found an issue with import cancelled recurrence .ics events which affected by caldav import also.

Steps to reproduce (simple version without caldav server)

1. Create recurrence event with one participant
2. Delete/cancel one event from recurrence with notify participant
3. Download received event of cancellation
4. Try to import this event to the Thunderbird calendar

Issue caused by:

• The problematic line is: "RECURRENCE-ID;TZID=Europe/Berlin:20240208T140000"

If i delete this line, the import works as expected.

Can you help with this?

Thanks! BR, Z

Hi,

I recently installed a CalDAV server at my workplace to connect to in the Thunderbird calendar, as we all already use Thunderbird for e-mail.

If I create a meeting in the calendar and invite everyone else, they all get an email invite with the name, time & place of meeting etc.. And at the top of the email, just below the title of the email, there is a purple bar with boxes saying "Accept", "Tentative", "Deny" and "More" (or something synonymous, I have it in Swedish).

For one employee that purple bar with the "Accept"-box does not appear, and the only way for him to get the meeting to his calendar is by downloading the "invite.ics" file that is attached and importing it afterwards.

I have added two screenshots showing what I mean. One with the Accept, Deny etc. and the one person's e-mail that doesn't have the boxes.

We have checked his settings without finding anything that seems wrong in first glance. I have checked the caldav user account but the user account has the same settings as the others. Thunderbird is updated to the latest version (115.7.0, same as I use and it works for me).

When he invites people to a meeting they all get the invite correctly, so nothing is wrong when he creates a meeting invitation, only when he recieves an invite.

What could be wrong? Is there a setting he might've activated/deactivated in Thunderbird that we missed when looking or could there be something else we have thought of?

Thanks, Tim

When scheduling on Calendar, it is set to "Contacts," and I have to manually click on that box and change it to my e-mail each time I schedule something. I can't find how to make my e-mail the default. Help?

Calendar print shows two items where only one exists. See attachments of both the original Google Calendar and the TB calendar prints. If only one of the calendars is selected, the print is correct

I use Thunderbird calendar for all my events and without it I am lost. Yesterday, I wanted to export my calendar to be imported later by an online platform. I used the export function. I noticed however, that under the name of my calendar on the left pane this has appeared ( . export). I thought the ics file is already created, so I went ahead and deleted the strange ". export" item that appeared under my calendar name in the left pane. What happened next was that all my events disappeared from my normal calendar window. My question is how I can get back all my events? Or how I can restore the ". export" so my events come back.

Additional information: I did not have backup for my calendar. I cannot locate anywhere the ics file I thought it is "exported" I am using the latest version of Thunderbird as of March 2024.
