Thanks @ohrenkino for your quick response.
Is there a way to have a more precise formula? If I have the «-» data in the TITLE tag, it will be replaced by «/»

Please show us the details in a screenshot from Alt +T to see where and how exactly your current dates are formattted.
In your initial question you speak about the tags
START DATE
and
END DATE
Now you speak about
TITLE
?
What Field exactly did you use in your first replace attempt?

Sorry @LyricsLover and @ohrenkino, I misinterpreted the answer...
I ran the test again with ohrenkino data, and it works perfectly. 👍
Another question: can I place two tags in the
Replace
Field
at the same time? START DATE and END DATE

No, you can only select 1 target field at a time.
There are a few special "Fields" like \_ALL or \_TAG, but you loose control over what fields will be changed.

I would NOT recommend to use this special fields until you are absolutely sure what they do.

Thanks @LyricsLover, for your answer, I will do a programming, for the 2 tags

@Sergius FYI - you should be marking the solution on the post made by the person providing the details!

Great idea @MotleyG, I'll make a little video...

Here's a short video
To edit the data for both tags: | START DATE | END DATE | with Actions (Quick) Mp3tag
Data received for the START DATE and END DATE tags:
mm-dd-yyyy «-»
Data to edit for the START DATE and END DATE tags:
mm/dd/yyyy «/»

Here's a second video
You can also program using the «Actions», command in Mp3tag, thanks to @ohrenkino and @LyricsLover for showing me, how to program with this command.
The two tags: | START DATE | END DATE | change «-» by «/»
You can program your 2 tags semi-automatically with Mp3tag «Actions», after programming, you can execute the «Actions» command for your 2 tags with just one mouse click.

Just a hint: If you want to have more or less the same action only for different fields, it would be easiest to copy (there is a button for that) the action and set the new field name.
Everything else could stay the same.

Not in this action type. You could use "Guess value" as described here:

(just this post as example, the rest of the thread does not help)

Thanks @ohrenkino for this fairly detailed information. @LyricsLover also wrote me some examples.
Ohrenkino, I'm working on some of my tags with ('Album') ('EP') ('LP') ('Single')
If one day I need to program this type of data with Actions, I'll run some tests. If it doesn't work, I'll write on the Mp3tag Community to see if we can program them.
Thanks for your help, Ohrenkino, and the other volunteers too, and Florian, who gives us great updates with new features that sometimes impress me...
