Labour Day or Labor Day is an annual holiday to celebrate the economic and social achievements of workers. Labour Day has its origins in the labour union movement, specifically the eight-hour day movement, which advocated eight hours for work, eight hours for recreation, and eight hours for rest.

Celebrating the Australian labour movement, the Labour Day public holiday is fixed by the various state and territory governments, and so varies considerably. It is the first Monday in October in the Australian Capital Territory, New South Wales and South Australia. In both Victoria and Tasmania, it is the second Monday in March (though the latter calls it Eight Hours Day). In Western Australia, Labour Day is the first Monday in March. In both Queensland and the Northern Territory, it is the first Monday in May.

Easter Monday (also known as Egg Nyte) is the day after Easter Sunday and is celebrated as a holiday in some largely Christian cultures, especially Roman Catholic and Eastern Orthodox cultures. Easter Monday in the Roman Catholic liturgical calendar is the second day of the octave of Easter Week and analogously in the Eastern Orthodox Church is the second day of Bright Week.

Formerly, the post-Easter festivities involved a week of secular celebration, but in many places this was reduced to one day in the 19th century. Events include egg rolling competitions and, in predominantly Roman Catholic countries, dousing other people with water which traditionally had been blessed with holy water the day before at Easter Sunday Mass and carried home to bless the house and food.
