If this is Windows 10 then have you changed the taskbar buttons to small ones?
(Note this option is not available in Windows 11).
When you use the small buttons you get a thinner taskbar, but it then only has space to show the time in the System Tray and not both time and date.
Right-click anywhere on the Taskbar and select 'Taskbar Settings'.

I doubt that CCleaner would do that.

Nope.
Did not help.
Windows 10: yes
When I get a windows update I get date settings back.
If so then I would stop doing that, it is not meant to be used regularly.
Registry cleaning is an advanced tool sometimes used when trying to fix an already broken machine.
Using it regularly on a machine that isn't broken runs the risk of breaking something, or even bricking the whole machine, - you will find posts in this forum where exactly that has happened.
Registry cleaning will not make your machine run any faster, or any 'better', and the space it may save is only a few KB.
Windows 10/11 changes the registry too often to make using any registry cleaner totally safe.

Date disappeared after normal CCleaner.
I do not use Reg cleaner that often.
Just checking if anyone else get this date problem .....
<div class="ipsQuote_contents">

I'm just fishing here but could you try to make the taskbar a little bit bigger to see if the date pops up? This suggestion is based on one of the answers here <a href="https://answers.microsoft.com/en-us/windows/forum/all/taskbar-does-not-show-date/f2764f6f-d1cc-482c-ab4f-dce871b0afa1" rel="external nofollow">https://answers.microsoft.com/en-us/windows/forum/all/taskbar-does-not-show-date/f2764f6f-d1cc-482c-ab4f-dce871b0afa1</a> (the second one)

I don't recall anyone report this happening before, and I've been on the forum a number of years now.
</p>
<p>
Are you running Health Check or Custom Clean when it happens?
</p>
</div>
I do the upper heart CCleaner run.
But I have some adjustments in the second button.
Do the second button effect the upper Heart button when run ?
<div class="ipsQuote_contents">
<p>
No that are not the same.
</p>
<p>
The Heart is Health Check, which uses it's own cleanng rules, and checks for software updates, etc.
</p>
<p>
The other is Custom Clean, which as the name says you can customize what gets cleaned or not.
It just does cleaning and nothing else.
</p>
<p>
The only thing that currently gets shared between the two is if you have set any cookies to be kept and not cleaned.
</p>
<p>
I'm still not sure why Health Check appears to be affecting the time/date in your System Tray, but nobody else is reporting the same thing happening.
I can only think that it is something unusual in your Windows settings on that machine, Just what that 'something' may be is another question.

The old "Have you tried turning it off and then on again?" became a cliche for a reason - it often works.
Nowadays I would modify it though.
Intead of turning off and then on again do a 'Restart' from the Power button in Start.
With Windows 10 and 11 a 'Restart' clears more of the Windows Kernel than just Shutting Down and Rebooting clears.

Good to hear that you seem to have sorted it out.
