Hi! Take a look at:
http://www.ruby-doc.org/core-1.9.3/Enumerable.html#method-i-group_by and http://www.ruby-doc.org/core-1.9.3/Enumerable.html#method-i-collect I think they could help. E.g: hash = Time.all.collect { |t| [ t.date , t.hour ] }.group_by { |date,hour| date.strftime("%-m/%-d/%Y") } I hope it works.
