In New Zealand, Labor Day is a public holiday held on the fourth Monday in October. Its origins are traced back to the eight-hour working day movement that arose in the newly founded Wellington colony in 1840, primarily because of carpenter Samuel Parnell's refusal to work more than eight hours a day. He encouraged other tradesmen also to work for only eight hours a day and in October 1840, a workers' meeting passed a resolution supporting the idea. On October 28, 1890, the 50th anniversary of the eight-hour day was commemorated with a parade. The event was then celebrated annually in late October as either Labor Day or Eight-Hour Demonstration Day. In 1899 government legislated that the day be a public holiday from 1900. The day was celebrated on different days in different provinces. This led to ship owners complaining that seamen were taking excessive holidays by having one Labor Day in one port then another in their next port. In 1910 the government stipulated that the holiday would be observed on the same day throughout the nation.

Celebrating the Australian labor movement and specifically the achievement of a working day limited to eight hours, the Labor 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, South Australia and, since 2013, Queensland. In both Victoria and Tasmania, it is the second Monday in March (though the latter calls it Eight Hours Day). In Western Australia, Labor Day is the first Monday in March. In the Northern Territory, it is the first Monday in May.

What does the underlined pronoun It in paragraph B refer to?

Labor Day (Labor Day in the USA) is an annual holiday to celebrate the achievements of workers. Labor Day has its origins in the labor union movement, specifically the eight-hour day movement, which advocated eight hours for work, eight hours for recreation, and eight hours for rest. For many countries, Labor Day is synonymous with, or linked with, International Workers' Day, which occurs on 1 May. For other countries, Labor Day is celebrated on a different date, often one with special significance for the labor movement in that country. In Canada and the United States, Labor Day is the first Monday of September and considered the official end of the summer holiday for most of the respective countries, as public school and university students return to school that week or the following week.
