 Just provide the symbol as the option value like so:
 
-  validates_date :birth_date, :on_or_before => :today
+  validates_date :birth_date, on_or_before: :today
 
 The :today symbol is evaluated as <tt>lambda { Date.today }</tt>. The :now and :today
 symbols are pre-configured. Configure your own like so:
 
   # in the setup block
   config.restriction_shorthand_symbols.update(
