4d result draw days are held three times every week throughout the calendar year. Every Wednesday, Saturday and Sundays are the scheduled draw days. This does not mean that you can only place on the 4d numbers on these days.
Advanced placement are also permitted but on 4d draw days, it closes at 7.00pm. On certain days when a public holidays happen to fall on a Tuesday, there could be additional draw days with special permission granted by the Treasury Department. You will find these information posted on the walls of the shop outlets usually 1 or 2 weeks before the special draw days.
