+## Ranges
+
+A Range can be converted into either a `Timespan` or a `DurationRange`
+
+### DurationRange
+
+```ruby
+dr = (1..5).days # => DurationRange 1..5, :days
+ts =(1..5).days(:timespan) # => Timespan start_date: 1.day.from_now, end_date: 5.days.from_now
+
+dr.between?(4.days) # => true
+```
+
+You can also use Range#intersect from *sugar-high* gem to test intersection of time ranges ;)
+
+### Timespan
