This works but can you please tell for what we use "TZ" and "CST"???

The 'TZ' parameter permits overriding the default time zone. 'CST' is the name of a timezone.

So CST+24 and then the date command.....

so how does the time zone gets set.......

I have a Q. what is the difference between CST & PST?

TZ=CST+24 date %d
TZ=PST+24 date %d

if I want to get the "day" of a date, instead of using `datecalc -D {date}`, any other options?

The clever shell scripter is using an undocumented feature of the time zone command. It worked for +48 and -168 when I tested, but adding a semicolon to end the command ruins it. The CST is "Central Standard Time".
