Hi Gosar,

In your irb example you have DATE::ABBR_MONTHS instead of
Date::ABBR_MONTHS. In this case Ruby interprets DATE as a constant
instead of a class, therefore you get an error. Here's my output:

irb(main):001:0> require 'date'
=> true
irb(main):002:0> Date::ABBR_MONTHS
=> {"oct"=>10, "jul"=>7, "jan"=>1, "dec"=>12, "jun"=>6, "apr"=>4,
"feb"=>2, "may"=>5, "sep"=>9, "aug"=>8, "mar"=>3, "nov"=>11}
irb(main):003:0> DATE::ABBR_MONTHS
NameError: uninitialized constant DATE
from (irb):3


HTH.

Regards,

Chris
