Change long date format in Sequoia 15.5

How to get Sequoia 15.5 to display the long date as,
Mon mm/dd/yyyy hh:mm am/pm

Thanks!

The best that you can do is "Day of Week mm/dd hh:mm am/pm}.

You do this by going to System Settings -> Control Center. Scroll down to the Menu Bar Only section and click on Clock Options.

Not what I'm talking about.

There is this:

System Settings > Keyboard > Keyboard Shortcuts > Services > Text > Word Service: Insert Long Date & Time

I have mine set to Ctrl+1 and this produces:
Monday, 06/23/2025 10:27 AM at 10:27:08 AM
NOTE: the time is duplicated - I want to remove the 2ns timestamp
ALSO: I want the date & time to show as: Mon 06/23/2025 10:27 AM
No comma (,) between the day of the week and the date.
And the day of the week should only be three (3) letters.

Ideas?

Cannot be done with macOS native System software.

Is there a 3rd party solution?

Possibly, but I don't know of one personally, where are you inserting this, into what? I mean, is this for documents or spreadsheets? Obviously word processors vary and all have their own settings for formatting date insertion or are we just talking about the System Menu Bar display? If so there are applications to customise System Display but they are complex, expensive and are unlikely to list such a feature in their product description.

With respect, can I ask why you want to modify the Time/Date display?
