Singapore Public Holidays

(a) Not all Muslim festivals listed above are national holidays, but all will affect Muslim businesses. Muslim festivals are timed according to local sightings of various phases of the moon and the dates given above are approximations. During the lunar month of Ramadan that precedes Hari Raya Puasa (Eid al-Fitr), Muslims fast during the day and feast at night and normal business patterns may be interrupted. Many restaurants are closed during the day and there may be restrictions on smoking and drinking. Some disruption may continue into Hari Raya Puasa itself. Hari Raya Puasa and Hari Raya Haji (Eid al-Adha) may last anything from two to 10 days, depending on the town. (b) Hindu festivals are declared according to local astronomical observations and it is only possible to forecast the month of their occurrence.
