The fourth test test if the date objects are being set up correctly.

@wchargin, I think it's fine to use the ternary ? operator here. Is that what you meant by this isn't very Ruby?

Thanks @mcclaskc!

I remember having a weird logic problem somewhere which happened because I was using 'and' instead of &&, but I cannot seem to replicate it - my apologies for starting this thread! ><

haha, you're welcome :)

This is not a good solution because "and" should not be used for logic evaluations in Ruby - "and" is a control flow operator, while && is a boolean operator.

See http://devblog.avdi.org/2010/08/02/using-and-and-or-in-ruby/ for more info.

Basically this code seems to work, but continuing to use "and" for boolean logic can create unexpected problems.
