Hi,
The relieving letter should be given on the last day of the employee in an organisation mentioning "the employee has been released in the closing hours of the day(last date). Before giving the relieving letter, just make sure that no dues pening from the employee to the organization, eg. Loan, salary advance, short fall of notice period counting from the last day of the employee in the organization. The full and final settlement include the amount due from the organization to the employee(if any, usually the last month salary) and the experience cirtificate of the employee.
