If you have a date, and you want to increment it by 1. You can do this by adding the date with a date interval. You can also do this by adding the number 1 directly on the date. The tutorial example below shows you how to adding numbers to dates, and take date differences:

SELECT TO_DATE('30-APR-06') + 1 FROM DUAL;
  -- Adding 1 day to a date
01-MAY-06 

SELECT TO_DATE('01-MAY-06') - TO_DATE('30-APR-06')
  FROM DUAL;
  -- Taking date differences
1

SELECT SYSTIMESTAMP + 1 FROM DUAL;
  -- The number you add is always in days.
08-MAY-06

SELECT TO_CHAR(SYSTIMESTAMP+1,'DD-MON-YYYY HH24:MI:SS.FF3')
  FROM DUAL;
-- Error: Adding 1 to a timestamp makes it a date.
