ACCURAL INCOME and Due Income

due means right to recieve and earned as well,but accrue means earned only,take the example of deb.interest due date of which is may31,n nov.30,here as on 31 march 4 month int.is earned but int,due will b on may 31 when right will b there to recieve

right like in many offices salary is paid on 7th of next month

in that case salary is given for the previous month, services are already given and salary is accrued but will be due (right to ask for salary) will arise on 7th only

pls. corect me if i m wrong !!!
