The markets will be on the 23rd March. They take place on the 4th Sunday of every month, as the traveller above mentioned, even on months with 5 Sundays (which March 2015 does). If that date doesn't work for you, the Byron markets are good too but they can be very busy. Personally, I prefer Bangalow. Just do a bit of Googling. Cheers.
Farmers markets are every Saturday 8-11am and community markets are fourth Sunday of the month. There are many other good markets eg Byron Bay Farmers market and BB community market. Search on web for 'markets northern rivers NSW' for dates and times. Hope this assists.
