+# Create A Date With The Date Sigil
+
+Elixir 1.3 introduced a new sigil for creating dates, `~D`. It works in the
+same way as Date's
+[`new/3`](http://elixir-lang.org/docs/stable/elixir/Date.html#new/3)
+function producing the Date struct with each of the date parts.
+
+```elixir
+> ~D[2016-01-01]
+~D[2016-01-01]
+iex(7)> ~D[2016-01-01].year
+2016
+iex(8)> ~D[2016-01-01].month
+1
+iex(9)> ~D[2016-01-01].day
+1
