I assume that you're adding the month and then the rest because you didn't want a 0-padded month.  If that's right, then I think that this would work and be a little better: `starting_at.strftime('%-m/%e/%Y')`

Documentation for this method and the format strings are here: [Time#strftime](http://www.ruby-doc.org/core-2.1.0/Time.html#method-i-strftime)
