I want to get rid of the 64-bit OS forever!, and to revert to my previous Mojave. I have a Time Machine b/u drive. What is the easiest way to do this?I use an iMac from 2017.

It's doable, but it's no picnic.
If you have a Time Machine backup of your Mojave system and files, one that has not since been used by macOS Ventura, then you can use that to restore your system to it's previous state.
To restore your Mac from the Mojave backup, you should first follow the guidance of those above and create a bootable Mojave installer before doing anything else. Test it when done to make sure you've got it right.
After that you can restart the Mac in Recovery mode and prep the drive for the older OS.
Use macOS Recovery on an Intel-based Mac - Apple Support
Use Disk Utility to erase and reformat the drive for use with Mojave.
With that done you would use the Install macOS utility to reinstall the Mojave system from the Time Machine backup drive.
From one use to another though, if it were me, I'd upgrade my workflow rather than downgrade my Mac.
You do you. 👍🏽

Mojave is a 64-bit operating system that is the last release of macOS that supports some 32-bit compatible applications, drivers, and libraries. As mentioned elsewhere in this post, Mojave is neither supported nor receiving updates of any kind from Apple. Many third-party application vendors no longer release products compatible with Mojave or attempts to reinstall their software may fail owing to their discontinued license servers for that platform.
I do not recommend reverting to Mojave from Ventura. There are dragons in that approach…
Follow the advise regarding making a Bootable Installer of Mojave .
This method will WIPE ALL Data and there is No DATA Recovery - Period.
To perform this action will require booting from a Bootable Installer.
The Bootable Installer can Only be performed on an Apple Computer
This will have to be performed from a Qualifying Computer to run the version of macOS to be made on the Bootable Installer.
Example : Bootable Installer of Mojave would have to be done on a computer that Qualifies to run Mojave.
Notation: If the computer being used to perform this action is Too New or Too Old to qualify to run the version of macOS - this computer can’t be used.
Alternative is, to gain access to a Qualifying Apple Computer from a family member, friend or associate.
Shutdown computer and disconnect all external drive Except the newly created Bootable Installer.
Restart and immediately hold the OPTION key until the Startup Manager appears and choose the USB Drive.
It will present options >> Disk Utilities >> View >> View ALL attached Drives.
Choose the Upper Most Drive ( not the volumes indented and list below ).
The drive normally is called Apple Media or Apple SSD - that is the drive to Erase and format as APFS with the GUID Partition Map.
Once that is done >> backup out of Disk Utilities and choose install macOS.
Follow the prompts and it may automatically reboot several time.
Upon a final reboot - Setup Assist will present with the newer version of macOS.
You must make a USB Installer for Mojave & erase the Ventura drive...

FWIW, that is incorrect. the Mac OS has been 32/64-bit since OS X 10.6 Snow Leopard. As Viking pointed out, Mojave was the last version to support 32-bit apps.
Marketing ploy - that’s funny. But no, it’s a response to all the hardware vendors moving to 64-bit architectures and the related expanded address space that comes with that.
32 bit architectures were too limited for the kinds of changes introduced at the time.
Just like 16-bit architectures once were - and I’m sure once upon a time someone thought 32-bit was an unneeded marketing ploy too.
FWIW, Mojave is no longer supported by Apple and some current software may not run.

That is correct... and still I prefer a 32-bit OS. My design work is in 32-bit... and so far the 64-bit I find to be no more than a marketing ploy.
That is correct and the reason I want to revert to 32-bit which is all my design work.
Why would you downgrade from 13.0 (Ventura) to 10.14 (Mojave)
?
How do I downgrade my OS from macOS Ventura to macOS Mojave?
