==Why have different date handlers?==

Different cultures and regions tend to have specific and different conventions for parsing and displaying dates. For example, the month and day order is different between most european coutries and the US. Also, each language has its own set of acceptable modifiers and qualifiers for the date: things like "from X to Y" or "between X and Y" may have different word order in different languages. Same with "around", "calculated", "estimated". Add to this calendar names and you have a compelling need for a dedicated date handler.
