Er, under what UI? Text/console? WxRuby? RubyCocoa? Rails?

Under the guess that you’re confusing “Ruby, the Language” with “Ruby on  
Rails, the Web Framework that happens to be implemented using Ruby”, you  
might want to re-ask your question on the Ruby on Rails group:  
[http://groups.google.com/group/rubyonrails-talk](http://groups.google.com/group/rubyonrails-talk)

How about this hack that probably fails near the last day of the month:

require ‘date’  
d1 = “12/2006”  
d2 = “13/2007”  
d3 = “10/2005”  
d4 = “11/2006”  
d5 = “12/2006”

[d1,d2,d3,d4,d5].each{ |datestring|  
begin  
d = Date.strptime( “28 #{datestring}”, ‘%d %m/%Y’ )  
raise if d \< Date.today  
puts “OK: #{d}”  
rescue  
puts “BAD DATE: #{datestring}”  
end  
}

#=\> OK: 2006-12-28  
#=\> BAD DATE: 13/2007  
#=\> BAD DATE: 10/2005  
#=\> BAD DATE: 11/2006  
#=\> OK: 2006-12-28

Sorry, I definitely should have been clearer.

Under Rails I was also thinking Javascript/Ajax (technically). I’ll  
ask over in the RoR group too.

I asked the question here because I was thinking the validation would  
be in Ruby.

Thanks Paul and Gavin,
