Non-Gregorian dates especially Hijri date (new feature)

[Ashamandi]

DateJs is supporting Gregorian date only ... what about other non-gregorian dates ?

for example, Many Arabic countries (like Saudi Arabia) use Hijri calendar ( wiki link ) in their daily activities which totally has different calculation than the Gregorian one so I think it is very important to have a hijri date object to easily make calculations on it like you do at Gregorian date.

if you have the interest, let's discuss how to support it.

Any comment here please?

I am a Bidi developer at Globalization team - IBM Egypt, My team is responsible to support globalize and bidi features at open source technologies that IBM Products use and this feature is very important for us to solve many issues we face at supporting national calendars in many open sources that directly/indirectly use Date js object like (D3, NVD3, Brunel).

Please take a look at this issue d3/d3-time#23, This proves that if we support non-gregorian date here "@ DateJs" we can easily remove many obstacles at D3 as an example.
