Hi,
You can use the age() function to find the difference between dates, and
use the extract() function to get the years, months, days, etc.

this will not work because age('25/12/1975','30/01/1986')
wil return '10 year 1 month 5 days'

extract only returns years -10, moths-1, days-5.

this is not i want.Actual month  difference between the dates are 121 months.
