The National Day is a designated date on which celebrations mark the nationhood of a nation or non-sovereign country. This nationhood can be symbolized by the date of independence, of becoming a republic or a significant date for a patron saint or a ruler (birthday, accession, removal, etc.). Often the day is not called "National Day" but serves and can be considered as one. The National Day will often be a national holiday.
Many countries have more than one National Day. For example, Pakistan has three National Days, none of which is named the "National Day". This signals the use of a "class" of National Days, that are equally important in the foundation of the nation, and a "class" of less important official public holidays.
Most countries have a fixed date National Day, but some have movable dates. An example is Jamaica, which up to 1997 celebrated its National Day on the first Monday in August. This commemorated independence from the United Kingdom which was attained on Monday, 6 August 1962, the first Monday in August of that year. Israel's Independence Day is not fixed relative to the civil Gregorian calendar, being formally linked to 5 Iyar on the Jewish calendar, but may also be moved to any day between 3 and 6 Iyar in order to avoid preparing for or celebrating either Independence Day or Memorial Day (which immediately precedes Independence Day) on Shabbat; the practical effect of this is that Independence Day may be celebrated any day between 15 April and 15 May. Another example is Thailand which celebrates the birthday of the king on 5 December. This date will change on the accession of the heir to the throne.
Australia Day is the official National Day of Australia. Celebrated annually on 26 January, it marks the anniversary of the 1788 arrival of the First Fleet of British Ships at Port Jackson, New South Wales, and the raising of the Flag of Great Britain at Sydney Cove by Governor Arthur Phillip. In present-day Australia, celebrations reflect the diverse society and landscape of the nation, and are marked by community and family events, reflections on Australian history, official community awards, and citizenship ceremonies welcoming new immigrants into the Australian community.
The meaning and significance of Australia Day has evolved over time. Unofficially, or historically, the date has also been variously named "Anniversary Day", "Foundation Day", and "ANA Day". 26 January 1788 marked the proclamation of British sovereignty over the eastern seaboard of Australia (then known as New Holland). Although it was not known as Australia Day until over a century later, records of celebrations on 26 January date back to 1808, with the first official celebration of the formation of New South Wales held in 1818. On New Year's Day 1901, the British colonies of Australia formed a Federation, marking the birth of modern Australia. A national day of unity and celebration was looked for. It was not until 1935 that all Australian states and territories had adopted use of the term "Australia Day" to mark the date, and not until 1994 that the date was consistently marked by a public holiday on that day by all states and territories.
Belgian National Day (Dutch: Nationale feestdag van België; French: Fête nationale belge; German: Belgischer Nationalfeiertag) is the National Day of Belgium celebrated on 21 July each year. It is one of ten public holidays in Belgium.
The festival's formal establishment dates to a law of 27 May 1890 and commemorates an event on 21 July 1831 in which Leopold of Saxe-Cobourg swore allegiance to the new Belgian constitution, thus becoming the first King of the Belgians. The king's vow marked the start of the independent state of Belgium under a constitutional monarchy and parliament.
In 1830, drawing inspiration from the recent July Revolution in France, the southern provinces of the United Netherlands rebelled against Dutch rule after a period of growing economic and religious disparity and political alienation. The Dutch were forced out of much of the area and Belgium gained de facto independence. A National Congress was created to write a Constitution for the new state.
