Are Buddhist Insignificant?

or

WCIT, one of the world's most important event on information was held in Malaysia for the first time. The opening day coincided with the most important Buddhist holy days - Wesak Day. Incidentally, Wesak Day is a national holiday in Malaysia.

I wonder if the WCIT in Malaysia would ever be held on a Hari Raya or Christmas day? Are Buddhists important? It is important enough for Wesak Day to be made a National Holiday though. So why is such an important event have to held on this day, especially one day before that, the Malaysian PM made a historic visit to the Buddhist Maha Vihara?

So much appreciating each other's culture and religion.
