+# Constructing A Range Of Dates
+
+PostgreSQL offers a number of range types including the `daterange` type.
+This can be constructed using the `daterange()` function with two strings
+representing the lower and upper bounds of the date range respectively.
+
+```sql
+> select daterange('2015-1-1','2015-1-5');
+        daterange
+-------------------------
+ [2015-01-01,2015-01-05)
+```
+
+The lower bound is inclusive -- indicated by the `[` character -- and the
+upper bound is exclusive -- indicated by the `)` character.
