π Happy Nowruz
Nowruz (Persian: ΩΩΨ±ΩΨ²β, pronouncedΒ [nowΛΙΎuΛz]; lit.β "new day") is the Iranian New Year, also known as the Persian New Year, which is celebrated worldwide by various ethno-linguistic groups.
Nowruz has Iranian and Zoroastrian origins, however, it has been celebrated by diverse communities for over 7,000 years in Western Asia, Central Asia, the Caucasus, the Black Sea Basin, the Balkans, and South Asia. It is a secular holiday for most celebrants that is enjoyed by people of several different faiths, but remains a holy day for Zoroastrians, Bahais, and some Muslim communities.
Nowruz is the day of the vernal equinox, and marks the beginning of spring in the Northern Hemisphere. It marks the first day of the first month (Farvardin) of the Iranian calendars. It usually occurs on March 21 or the previous or following day, depending on where it is observed. The moment the Sun crosses the celestial equator and equalizes night and day is calculated exactly every year, and families gather together to observe the rituals.
While Nowruz has been celebrated since the reform of the Iranian Calendar in the 11th century CE to mark the new year, the United Nations officially recognized the "International Day of Nowruz" with the adoption of UN resolution 64/253 in 2010.

π The Negro Motorist Green Book
The Negro Motorist Green Book (also The Negro Motorist Green-Book, The Negro Travelers' Green Book, or simply the Green Book) was an annual guidebook for African-American roadtrippers. It was originated and published by African American, New York City mailman Victor Hugo Green from 1936 to 1966, during the era of Jim Crow laws, when open and often legally prescribed discrimination against African Americans especially and other non-whites was widespread. Although pervasive racial discrimination and poverty limited black car ownership, the emerging African-American middle class bought automobiles as soon as they could, but faced a variety of dangers and inconveniences along the road, from refusal of food and lodging to arbitrary arrest. In response, Green wrote his guide to services and places relatively friendly to African-Americans, eventually expanding its coverage from the New York area to much of North America, as well as founding a travel agency.
Many black Americans took to driving, in part to avoid segregation on public transportation. As the writer George Schuyler put it in 1930, "all Negroes who can do so purchase an automobile as soon as possible in order to be free of discomfort, discrimination, segregation and insult." Black Americans employed as athletes, entertainers, and salesmen also traveled frequently for work purposes.
African-American travelers faced hardships such as white-owned businesses refusing to serve them or repair their vehicles, being refused accommodation or food by white-owned hotels, and threats of physical violence and forcible expulsion from whites-only "sundown towns". Green founded and published the Green Book to avoid such problems, compiling resources "to give the Negro traveler information that will keep him from running into difficulties, embarrassments and to make his trip more enjoyable." The maker of a 2019 documentary film about the book offered this summary: "Everyone I was interviewing talked about the community that the Green Book created: a kind of parallel universe that was created by the book and this kind of secret road map that the Green Book outlined".
From a New York-focused first edition published in 1936, Green expanded the work to cover much of North America, including most of the United States and parts of Canada, Mexico, the Caribbean, and Bermuda. The Green Book became "the bible of black travel during Jim Crow", enabling black travelers to find lodgings, businesses, and gas stations that would serve them along the road. It was little known outside the African-American community. Shortly after passage of the Civil Rights Act of 1964, which outlawed the types of racial discrimination that had made the Green Book necessary, publication ceased and it fell into obscurity. There has been a revived interest in it in the early 21st century in connection with studies of black travel during the Jim Crow era.
Four issues (1940, 1947, 1954, and 1963) have been republished in facsimile (as of December 2017), and have sold well. Twenty-three additional issues have now been digitized by the New York Public Library Digital Collections.

π World War III
World War III or the Third World War, often abbreviated as WWIII or WW3, are names given to a hypothetical third worldwide large-scale military conflict after World WarΒ I and World WarΒ II. The term has been in use since at least as early as 1941. Some apply it loosely to limited or more minor conflicts such as the Cold War or the war on terror. In contrast, others assume that such a conflict would surpass prior world wars in both scope and destructive impact.
Due to the development and use of nuclear weapons near the end of World WarΒ II and their subsequent acquisition and deployment by many countries, the potential risk of a nuclear apocalypse causing widespread destruction of Earth's civilization and life is a common theme in speculations about a Third World War. Another primary concern is that biological warfare could cause many casualties. It could happen intentionally or inadvertently, by an accidental release of a biological agent, the unexpected mutation of an agent, or its adaptation to other species after use. Large-scale apocalyptic events like these, caused by advanced technology used for destruction, could render Earth's surface uninhabitable.
Before the beginning of World War II in 1939, World WarΒ I (1914β1918) was believed to have been "the war to end [all] wars." It was popularly believed that never again could there possibly be a global conflict of such magnitude. During the interwar period, World War I was typically referred to simply as "The Great War". The outbreak of World WarΒ II disproved the hope that humanity might have already "outgrown" the need for such widespread global wars.
With the advent of the Cold War in 1945 and with the spread of nuclear weapons technology to the Soviet Union, the possibility of a third global conflict became more plausible. During the Cold War years, the possibility of a Third World War was anticipated and planned for by military and civil authorities in many countries. Scenarios ranged from conventional warfare to limited or total nuclear warfare. At the height of the Cold War, the doctrine of mutually assured destruction (MAD), which determined an all-out nuclear confrontation would destroy all of the states involved in the conflict, had been developed. The absolute potential destruction of the human race may have contributed to the ability of both American and Soviet leaders to avoid such a scenario.
