Using DateDifference in Calculated Column in Attribute Views

Hi all,

I have created a calculated column in Attribute view wherein I am using DateDifference function

My structure is as follows -

As seen I am getting 1 day less than what is required whereas if start_dt and end _dt is same I am getting correct value

I am using the formula in my calculated column -

daysbetween(date(start_dt),date(end_dt))

Also If I am firing a direct query in SQL editor in HANA I am getting correct values.

select days_between(to_date(start_dt), to_date(end_dt)) from table_name

Kindly tell what is getting wrong above.
