     A simple script for searching the password for T5577. The script creates a
     dictionary starting from the entered starting year to the entered ending year.
     There are two search methods - DDMMYYYY or YYYYMMDD. Checking the entire year
-    takes about 1 minutes and 50 seconds. Date from 1900 to 2100. The script may be
