The function should return a tuple, not a list.

Stars are also used for markup, to make text bold or italic. So in the description they get omitted.

Try using ```*3*``` or \*3\* instead of *3*, to show the stars correctly.

Changing a commonly known term for no good reason is not the best approach. Leap years are very well defined, why change the definition of a leap year?

year1 is always less than year2.

test.assert_equals(count_days(2016, -7469), None)

• No random tests
• The description didn't mention the use of leap year, leaving ambiguity as to how many days a year would be in this kata.

Great
