In Judaism, the New Moon ushers in a new month

Rosh Chodesh or Rosh ḥodesh (Hebrew: ראש חודש‎; trans. Beginning of the Month; lit. Head of the Month) is the name for the first day of every month in the Hebrew calendar, marked by the appearance of the new moon. The new moon is marked by the day and hour that the new crescent is observed. It is considered a minor holiday, akin to the intermediate days of Passover and Sukkot.^[1]

Youth Day is a holiday dedicated to the youths of a country.

International Youth Day is an international observance on August 12 officially recognized by the United Nations.

Greenery Day (みどりの日, Midori no hi^?) is a Japanese holiday. Between 1989 and 2006 it was celebrated on April 29. In 2007 Greenery Day was moved to May 4.

The present observation of Greenery Day as a national holiday in Japan stems from the celebration of the Emperor Shōwa's birthday on April 29 every year during the Shōwa era. In 1989, following the ascension of the current Emperor Akihito to the Chrysanthemum Throne, the name of the holiday was changed from "Birthday of the Emperor" to "Greenery Day".^[1] Officially, as its name suggests, it is a day to commune with nature and to be thankful for blessings. The day was renamed to "Greenery Day" to acknowledge the controversial wartime emperor's love for plants without directly mentioning his name.^[2] However, in practice it is seen as just another day that expands the Japanese Golden Week vacation.

The Declaration "On the Restoration of Independence of the Republic of Latvia"^[1] (Latvian: Deklarācija Par Latvijas Republikas neatkarības atjaunošanu) was adopted on 4 May 1990, by the Supreme Soviet of the Latvian SSR. The Declaration stated that, although Latvia had de facto lost its independence in 1940, when it was annexed by the Soviet Union, the country had de jure remained a sovereign country as the annexation had been unconstitutional and against the will of the people of Latvia. Therefore it resolved that the Molotov-Ribbentrop Pact and the Soviet occupation of Latvia in 1940 were illegal, and annulled the declaration on the accession of Latvia to the Soviet Union of 21 July 1940, re-instituted the Constitution of Latvia of 1922, which was thereupon partly suspended, and set a period of transition to de facto independence, which would end upon the first session of Saeima. It also ruled that during the transitional period the Constitution of the Latvian SSR and other laws would remain applicable as long as they did not contradict articles 1, 2, 3, and 6 of the Constitution of Latvia, which were reinforced by the declaration. It was provided that a committee to elaborate a new edition of the Constitution of Latvia should be created. Social, economic, cultural and political rights were granted to citizens and residents of Latvia in accordance with international human rights. The declaration also stated that Latvia would form its relationship with the Soviet Union on the basis of the Latvian–Soviet Peace Treaty of 1920, in which the Soviet Union had recognized the independence of Latvia as inviolable "for all future time".^[2] The 4th of May is a national holiday in Latvia.

In its beginning the Declaration establishes several historical facts and on the basis of these facts concludes that the Republic of Latvia de jure is a sovereign country. It observes that the Republic of Latvia proclaimed independence on 18 November 1918, and was internationally recognized in 1920, and that Latvia was admitted to membership in the League of Nations in 1921.^[3] The first country to recognize the independence of Latvia de jure was Soviet Russia on 11 August 1920, when the Soviet-Latvian Peace treaty was signed (it is generally considered that the independence of Latvia de jure was internationally recognized on 26 January 1921, when it was recognized by the Allies of World War I).^[4][5] The declaration notes that in April 1920 the Latvian nation followed the principle of self-determination by electing a Constitutional Assembly of Latvia, which adopted the Constitution of Latvia on 15 February 1922, in general, equal and direct elections, based on proportional representation.^[3]

The Declaration of Independence was a statement adopted by the Continental Congress on July 4, 1776, which announced that the thirteen American colonies, then at war with Great Britain, regarded themselves as independent states, and no longer a part of the British Empire. John Adams put forth a resolution earlier in the year which made a formal declaration inevitable. A committee was assembled to draft the formal declaration, to be ready when congress voted on independence. Adams persuaded the committee to select Thomas Jefferson to compose the original draft of the document,^[2] which congress would edit to produce the final version. The Declaration was ultimately a formal explanation of why Congress had voted on July 2 to declare independence from Great Britain, more than a year after the outbreak of the American Revolutionary War. The Independence Day of the United States of America is celebrated on July 4, the day Congress approved the wording of the Declaration.

After ratifying the text on July 4, Congress issued the Declaration of Independence in several forms. It was initially published as a printed broadside that was widely distributed and read to the public. The most famous version of the Declaration, a signed copy that is usually regarded as the Declaration of Independence, is displayed at the National Archives in Washington, D.C. Although the wording of the Declaration was approved on July 4, the date of its signing has been disputed. Most historians have concluded that it was signed nearly a month after its adoption, on August 2, 1776, and not on July 4 as is commonly believed. The original July 4 United States Declaration of Independence manuscript was lost while all other copies have been derived from this original document.^[3]
