In the interests of accuracy, Ramadhan, which lasts some 28/29 days cannot
occur twice in a solar year.
It's the feast of Eid al-Fitr, the celebration that marks the end of the
fasting month, which _will_ (it's not happened yet) occur twice in 2000,
early last January and again around Christmas time.
Here in Malaysia, the sighting of the new moon is made from Singapore, and
in Brunei they do it for themselves. Since it's often cloudy, this can
result in a day's (no longer) delay, and in fact last Eid started a day
later in Brunei than in Malaysia.
Cheers
Dennis
