Oh! Okay, thank you!

Ah, ok thanks! Date class was new for me :)

Oh, thanks!
I wasn't aware of the duplicated strings in the result of rotation.

Yea, but the input was only a '#' character, how sould I count with that?

Ruby: It seems the last test case is wrong..

Expected: true, instead got: false
strng = "12341234",
arr = ["DIeF", "IeFD", "12341234", "41234123", "34123412", "23412341"]

How can this be true? arr doesn't seems to contain all the rotations

Ruby: day contains only a # ... :(
Pls fix it.

def days_until_christmas(day)
day
end

Basic tests
Expected: 16, instead got: #
Expected: 17, instead got: #
Expected: 18, instead got: #
Expected: 305, instead got: #
Expected: 167, instead got: #
Expected: 16, instead got: #
Expected: 282, instead got: #
Expected: 0, instead got: #
Expected: 364, instead got: #
Expected: 365, instead got: #

Smtg wrong with Ruby Random test...

Random tests
Testing for diFpFlyWfzXcEHNCIlz
It should work for random inputs too - Expected: "fX", instead got: "z"
Testing for sPSUvuIIrCZlcrYHino
It should work for random inputs too - Expected: "rZ", instead got: "C"
Testing for yCTuZX
It should work for random inputs too - Expected: "CZ", instead got: "Tu"
