The first two lines are correct, but the next two lines are mistaken.
4 March 1504 is Monday instead of Saturday.

I got a correct answer with my program as follows:

In this list Vikrama year is output as 1561 because my program
is Caitraai (already changed on Caitra zukrapratipad), but
if the calendar is Kaarttikaadi the year is still 1560.

I will soon upload the revised version pancanga3.10 in my
web page.
