Answer 1

Apache POI has some utilities for that http://poi.apache.org/apidocs/org/apache/poi/ss/usermodel/DateUtil.html, notably http://poi.apache.org/apidocs/org/apache/poi/ss/usermodel/DateUtil.html#getJavaDate(double)

Note Excel stores dates as the number of days (plus fractional days) since 1900 (and in some cases it can be from 1904). See http://support.microsoft.com/kb/180162.
