Rename old files with last modification date

Hi everyone,

I have files like file1_Mod.txt, file2_Mod.txt. I want to rename the old files with the last modification date. I write the below script to rename with current date, but I donīt know how to use "date -r" to get the last modification date with the same format I have below (dd-mm-yyyy_hhmmss).

The ouput I would like is:
file1_Old_dd-mm--yyyy_hhmmss.txt
file2_Old_dd-mm--yyyy_hhmmss.txt

Script what I have so far.
Code:
for each in *Mod.txt;
do
mv $each $(basename $each Mod.txt)Old_$(date +"%d-%b-%Y_%H%M%S").txt
done

May somebody help me with this issue.

Thanks in advance.
