The following query:

SELECT MONTHS_BETWEEN(DATE'1995-02-02', DATE'1995-01-01'); 

returns the result 1.03225806451612903225806451612903225806. The MONTHS_BETWEEN function calculates the fractional portion of the result based on a 31-day month and considers the difference in time components of date_timestamp_value1 and date_timestamp_value2.
