FD Interest - End Date not included in interest calculation

Hello Experts,

We are trying to calculate interest for fixed deposits. We want to calculate FD from 1st April 2013 to 30th September 2013 (183 days). It should be simple calculation like Rs.100000 * 10% *183 days / 365 days.

But system is excluding last date. Please check screenshot. I have tried by clicking on include end date. But its not showing expected output.

Expected result for interest amount is Rs. 5013.69 (rounded off to Rs. 5014). But system is calculating as per 182 days i.e. Rs. 4986.30 (rounded off to Rs. 4986).
