Details

The day count is determined after making the following (ordered) modifications:

1. If the start date is the 31st, set the start date to the 30th

2. If the end date is the 31st, set the end date to the 1st of the following month.

The year fraction is then calculated as: $$\frac{(d_2-d_1) + (m_2-m_1)\times 30 + (y_2-y_1)\times 360}{360}$$

The order of date1 and date2 is not important. If date1 is less than date2 then the result will be non-negative. Otherwise, the result will be negative.
