Feature

Date result = Chrono.ParseDate("July 15, 2014 6:41 p.m. ET");
// result == Tue Jul 15 18:41:00 CDT 2014

List<ParsedResult> results = Chrono.Parse("July 15, 2014 6:41 p.m. ET");
// results.get(0).text == "July 15, 2014 6:41 p.m. ET"
// results.get(0).start.date() == Tue Jul 15 18:41:00 CDT 2014
// results.get(0).end == null

List<ParsedResult> results = Chrono.Parse("at ... event on November 11-13. Read more: http://..");
// results.get(0).index == 16
// results.get(0).text == "November 11-13"
// results.get(0).start.date() == Tue Nov 11 12:00:00 CST 2014
// results.get(0).end.date() == Thu Nov 13 12:00:00 CST 2014

For basic parsing, simply pass a natural language String to function Chrono.Parse or Chrono.ParseDate.

• To get a quick date result, Chrono.ParseDate returns java.util.Date.
• To get every detailed information of date expession appeared in the text, Chrono.Parse returns List<ParsedResult>.
