Ronan d - Do you have a preference for the Calender used ?
Are you sticking with the Gregorian Calender and if so are you using the old calculations or the new ?
Do you wish to know when you are on the Hijri calender or perhaps the the Chinese calender?
You also have the choice of the Julian, Roman, Indian, Jewish, Coptic, Ethiopian, Persian, Balinese and Baha'i.
If you are the more forward looking type do you wish to know todays Stardate or the nearest Klingon Feast day to today ?
But more importantly if you don't know When you are how can you begin to find Who you are ? (Deep or wha'!)
