Will work for a single file
Code:
awk '
  /^Event/,/^END/ {
    i=$1
    sub($1,x)
    A[i]=$0
  } 
  /^Date/,/^END/ {
    if(NR>FNR && !/^END/) print $0 A[$NF]
  }
' file file

Appreciate the logic which simplifies the implementation.

1. The code does the job if file name is Specified manually,
but how to process multiple files(60-70 files) at one go as the same file name has to be mentioned twice. Now *.* can not be used ....

2. While executing in Terminal in a single line, Code is running fine, but while trying to run the same Code from a file, its waiting for input ...
Running in Terminal:

Script.sh File1 File1

Code in file "Script.sh"
Code:
awk '/^Event/,/^END/ {i=$1;A[i]=$0;} /^Date/,/^END/ {if(NR>FNR && !/^END/ && NF>4) {printf "%5s %2s %2s %15s %s\n" ,$1,$2,$3,$4,A[$NF]} }'

end

END(7)								   SQL Commands 							    END(7)

NAME

       END - commit the current transaction

SYNOPSIS

       END [ WORK | TRANSACTION ]

DESCRIPTION

       END  commits  the  current  transaction. All changes made by the transaction become visible to others and are guaranteed to be durable if a
       crash occurs. This command is a PostgreSQL extension that is equivalent to COMMIT [commit(7)].

PARAMETERS

       WORK

       TRANSACTION
	      Optional key words. They have no effect.

NOTES

       Use ROLLBACK [rollback(7)] to abort a transaction.

       Issuing END when not inside a transaction does no harm, but it will provoke a warning message.

EXAMPLES

       To commit the current transaction and make all changes permanent:

       END;

COMPATIBILITY

       END is a PostgreSQL extension that provides functionality equivalent to COMMIT [commit(7)], which is specified in the SQL standard.

SEE ALSO

       BEGIN [begin(7)], COMMIT [commit(7)], ROLLBACK [rollback(7)]
