I am trying to create a personal calendar as a checklist for chores. Is it possible to make a list of tasks without adding a time to each task? When I try to print the calendar, the time stamp takes a lot of space and is unnecessary for my purposes. Also, I have added birthdays/anniversaries/holidays to my calendar, and these also require an unnecessary time stamp. Is there a way to add these without an associated time?

When I add a calendar event, it defaults to Holidays in US. How do I change this to the calendar associated with my email address? I often forget to change the desired calendar. Also, How do I edit the Holidays calendar? Thanks BigSam

Cannot dismiss reminder or set the snooze. Get the following:

Status Code: 2147500037, The request cannot be processed.

An error occurred when writing to the calendar charles.novak@gmail.com! Please see below for more information.

Server Replied with 400 If you're seeing this message after snoozing or dismissing a reminder and this is for a calendar you do not want to add or edit events for, you can mark this calendar as read-only to avoid such experience in future. To do so, get to the calendar properties by right-clicking on this calendar in the list in the calendar or task view.

I use TB as a personal home email client & calendar. All the prenamed Category labels for events are primarily oriented to business use. If there a way to rename the Categories and apply a color that I want?

I'm trying to list future events in the T-bird Calendar without including my numerous daily reminders (mostly when I'm supposed to take my meds). Is there a way to suppress their inclusion? Or is there a way to enter daily events as a separate class that won't show up in the standard future events list? Thank you.

I have added my calendar to Thunderbird and it is syncing with Google but when I add a new event it only allows me to set one notification time. I have a standard notification of 30 minutes before something happens and in Google I can add additional notifications like a day before or a week before. I don't see that I can do that when I create the event in Thunderbird. Need to create all of my calendar events in my Google calendar?

I’m using Thunderbird on a MacBook Air M1 2020 with 103 GB of free disk space and 8 GB memory. I’m using it primarily as a calendar and task management system because I like the reminder options in Thunderbird. I use local calendars. Thunderbird auto-updated to V 128.5.2 from V115.18.0 on 12/17/24 (I didn’t realize auto-update was set) and since then gets hung every time a reminder comes up and I either dismiss it or snooze it. I have to Force Quit Thunderbird to get the spinning beach ball to go away. I backup my computer weekly using Time Machine and tried restoring to 115.8.0, but was unable to restore my profile with my current calendar items on it. I got an error message saying that the new version of my profile (with my local calendars) is incompatible with Thunderbird V 115.8.0. Is there any way to get my current calendar info into an older version of Thunderbird, or better yet, create a fix so that it doesn’t get hung? If it's time for me to move to a different application for this use, just be honest. Thanks in advance for your advice and expertise!

I'm trying to create an event that start from time in PST, and end in China Standard Time. However, the date time selector doesn't seems to be aware with the timezone I selected and still prompt that I selecting wrong time.

I'm on the latest stable Thunderbird release, 138

I have 4 gmail accounts in Thunderbird. The calendar shows items from all 4 accounts. My issue comes when setting up an invitation. Pretend my accounts are:

personal1@gmail.com personal2@gmail.com personal3@gmail.com business1@gmail.com

If I want to set up a meeting with invitations from business1@gmail.com, I select the account from the left side of the calendar list, then I create a new event on the day I want. The dialogue box correctly shows "business1@gmail.com in the Calendar drop down box at the top. I can then fill in title, location, category, time etc. But when I click on Invite Attendees, thunderbird has already added "personal1@gmail.com" as the first attendee and is waiting for me to enter the contact of the second attendee. If I add people and send it out, it goes from my "personal1" account and not my "business1" account and any replies come into "persoanl1". Same thing happens if I start by selecting the "personal2" or "personal3" accounts first in Calendar view. It always sets "personal1" as the organizer.

I can not figure out why Thunderbird is automatically using "personal1" as a default and sending from there. I am adding a screen shot to show what it looks like after adding an invitee.

When I add/edit a calendar event, it only allows for 1 reminder. I often set up multiple reminders for an event, especially if it is scheduled for several weeks in the future. I want to set up a reminder for '2 weeks before', '2 days before', and '12 hours before', but I can't find where to add the additional reminders.

I have been using ThunderBird on Linux Mint for some time now. I am using Outlook.com for emails, calendar and contacts and I sync with another laptop and mobile phone. All fine until a few days ago when I noticed calendar events were not syncing with my phone. I found one calendar event in ThunderBird had an error when I manually synced with TbSync. The error report did not say anything specific. I deleted this calendar event and TbSync ran successfully uploading 2 events that it had not uploaded due to the calendar sync error. I then wanted to manually recreate this calendar event in ThunderBird. When I clicked on "New Event", the Calendar New Event pop-up window did not appear. When I minimised the ThunderBird window, the New Events was not behind it. The ThunderBird icon pinned to the panel had a "2" in the corner. When I hovered over the ThunderBird icon in the panel, it showed both the ThunderBird window and New Event window preview. When I selected the New Event preview window in the panel, it still did not become visible. All I could do with with New Event preview window in the panel was click in the 'X' to close it. I checked for Lightning Calendar Tab add-on updates. It was up to date. I check the settings. All OK. I disabled and enabled this add-on. Still not working. My Windows habits made me shutdown and restart my device. Still Not working. When I checked the other ThunderBird functions, New Event pop-up windows appeared for Emails and Contacts but not Tasks which had the same symptoms as the Calendar.

When trying to edit the Description of a Calendar Event the description window only shows part of the first line. I am unable to scroll or resize the text box. Windows 11 64 bit, Thunderbird 1.28 and Thunderbird Eclipse 140.0.1 - 64 bit

Nach Update auf Release Kanal kein Geburtstagskalender mehr und Geburtstage werden nicht im Kalender angezeigt. Geburtstage in Kontakten vorhanden. Benutze keine Cloud und kein Google. Wie werden Geburtstage wieder im Kalender angezeigt?

I am trying to import a ics file into thunderbird. If I specify a local calendar as the destination calendar, the import works. However, if I specify a caldav-connected calendar as the destination, the import starts but never completes, and I always see an import status of 0%. I have tried importing into calendars from different caldav providers, but in all cases, the import fails. I would greatly appreciate your feedback. For me, this import is a convenient way to semi-automatically populate a web calendar.
