Therefore on the appearance of the new moon of Shawal, Muslims rejoice and celebrate Eid'l Fitr or better know locally as Hari Raya Puasa.
One of the truly Malaysian ways of celebrating is by holding 'open house'.
The 'open house' concept is probably an expansion of the 'mutual visitation' (ziarah menziarah) tradition of the Malay Muslim community which has been embraced by every community here in Malaysia. We visit friends and relatives on all festival days, be it Hari Raya, Chinese New Year, Deepavali or Christmas. No invitations are necessary, only make sure the person you are visiting will be at home and not 'balik kampung' (gone back to their hometown) or themselves gone visiting.
Politicians, never ones to not capitalize on a good thing, advertise their open houses through the local media. These are the ones which attract both foreign tourists and other local visitors.
