31blabla2020 is ok but 31blabla202020 was not acceptable before I could create the control statement on the regex. I want your help please.

What I have tried:

((([1-9])|([12][0-9])|(3[01]))(\w+)([12][0-9][0-9][0-9]))

Just a few interesting links to help building and debugging RegEx.
Here is a link to RegEx documentation:
perlre - perldoc.perl.org[^]
Here is links to tools to help build RegEx and debug them:
.NET Regex Tester - Regex Storm[^]
Expresso Regular Expression Tool[^]
RegExr: Learn, Build, & Test RegEx[^]
Online regex tester and debugger: PHP, PCRE, Python, Golang and JavaScript[^]
This one show you the RegEx as a nice graph which is really helpful to understand what is doing a RegEx: Debuggex: Online visual regex tester. JavaScript, Python, and PCRE.[^]
This site also show the Regex in a nice graph but can't test what match the RegEx: Regexper[^]

(([1-9])|([12][0-9])|(3[01]))([a-zA-ZİÜĞŞÇÖ]+)([12][0-9][0-9][0-9])

I designed such an expression with expresso. Problem solved. Thank you.

Add a start and end of string:

^...$

Get a copy of Expresso[^] - it's free, and it examines and generates Regular expressions.
