In Oracle 11g, To get the complete date from the Timestamp, use this-

Select TRUNC(timestamp) FROM TABLE_NAME;

To get the Year from the Timestamp, use this-

Select EXTRACT(YEAR FROM TRUNC(timestamp)) from TABLE_NAME;

To get the Month from the Timestamp, use this-

Select EXTRACT(MONTH FROM TRUNC(timestamp)) from TABLE_NAME;

To get the Day from the Timestamp, use this-

Select EXTRACT(DAY FROM TRUNC(timestamp)) from TABLE_NAME;
