Feature Request: Support for series of consecutive dates

If the query contains a series of day/dates an interval maybe a more reasonable result. For example, "for next Thursday and Friday night" should return interval interval(June 29, June 30). Currently, the return value is one of the dates and a bit ambiguous. Another example is a query "18th, 19th and 20th Dec" which currently returns December 20th and "18th Dec, 19th Dec and 20th Dec" currently returns December 19th. A better result would be an interval(December 18, December 20) in both cases.
