Thunderbird Calendar Date Format Unwanted Change
My Thunderbird Calendar has started displaying time in 24-hr format (HH:mm), while by Thunderbird eMail continues to display the ‘am/pm’ format (hh:mm tt), correctly using my laptop’s Windows 10 System format, as shown in Control Panel/Region/Formats tab. I’d like to get Calendar back to hh:mm tt, without loosing all my calendar data. I suspect the problem was caused by an interruption when downloading the latest Thunderbird update, so I’ve tried manually downloading and installing a fresh copy of Thunderbird Setup 102.0.3, but the time display format wasn’t fixed. Is there a reliable way to roll back to the previous version without losing what I’ve added to my calendar between the time this format change occurred and the time I first noticed the change?

I'm using Windows 10 and Thunderbird 102.0.3 I did have computer and therefore Thunderbird all using 24 hour.
re :as shown in Control Panel/Region/Formats tab.
I check that location on my computer and I have:
- Short time: h:mm tt
- Long time: h:mm:ss tt
However, Windows OS has two locations for setting up date/time etc. As you have the correct settings in the Control Panel/Region/Formats tab Please check the other method just in case something is out of synch with Windows. I have known this to occur before.
- In windows bottom search type: 'Date time' and selected 'Change the date and time'
- select : 'Date, Time and regional formatting'
- select 'Change data formats'
Please work through each one, maybe select one you do not want eg:24 hr and then reset to one you want to use as below.
- Set short time as : eg: 9:40 AM
- Set Long time as: eg: 9:40:07 AM
Note: Computer clock in bottom right changed to match selection.
Exit Thunderbird. Wait a few moments and then restart Thunderbird.
In my case result: all email and everything in calendar was now on the AM/PM 12 hour clock.
This didn't solve my problem, but two Thunderbird updates later did fix it!
