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
