 In 1977, the Quebec Parliament declared June 24 to be Quebec's National Holiday.Historically June 24 was a holiday honouring French Canada's patron saint, St. John the Baptist, which is why it is commonly known as "La Saint-Jean-Baptiste" (often shortened to "La St-Jean").On this day, the song "Gens du pays" by Gilles Vigneault is often heard and commonly regarded as Quebec's unofficial anthem.
