Context: The Bharatiya Mazdoor Sangh (translation: "Indian Workers' Union") is the largest central trade union organization in India.

Saint David (Welsh: Dewi Sant , Latin: "Davidus" ; 500 c. 589) was a Welsh bishop of Mynyw (now St Davids) during the 6th century; he was later regarded as a saint.  He is the patron saint of Wales.  David was a native of Wales, and a relatively large amount of information is known about his life.  However, his birth date is uncertain: suggestions range from 462 to 512.  He is traditionally believed to be the son of Saint Non and the grandson of Ceredig ap Cunedda, king of Ceredigion.  The Welsh annals placed his death 569 years after the birth of Christ, but Phillimore's dating revised this to 601. John of Giscala (Hebrew: יוחנן מגוש חלב‎ ‎ "Yohanan mi-Gush Halav" or "Yohanan ben Levi"), the son of Levi, (birth date unknown; death date after 70), was a leader of the Jewish revolt against the Romans in the First Jewish-Roman War, and played a part in the destruction of Jerusalem in 70 CE.  During the outbreak of the Jewish war with Rome, John had vied with Josephus (Joseph Mattithiah) over the control of Galilee and had amassed to himself a large band of supporters from Gischala (Gush Halab) and Gabara, including the support of the Sanhedrin in Jerusalem.

Sándor Csoma de Kőrös (] ; 27 March 1784/811 April 1842), born Csoma Sándor (Csoma being the family name) was a Hungarian philologist and Orientalist, author of the first Tibetan-English dictionary and grammar book.  He was called Phyi-glin-gi-grwa-pa in Tibetan, meaning ""the foreign pupil"" and was given the title of Bosatsu or Boddhisatva (Buddhist sainthood) by the Japanese in 1933.  He was born in Kőrös, Grand Principality of Transylvania (today Chiuruş, Romania).  His birth date is often given as 4 April, although this is actually his baptism day and the year of his birth is debated by some authors who put it at 1787 or 1788 rather than 1784.  The Magyar ethnic group, the Székelys, to which he belonged believed that they were derived from a branch of Attila's Huns who had settled in Transylvania in the fifth century.  Hoping to study the claim and to find the place of origin of the Székelys and the Magyars by studying language kinship, he set off to Asia in 1820 and spent his lifetime studying the Tibetan language and Buddhist philosophy.  Csoma de Kőrös is considered as the founder of Tibetology.  He was said to have been able to read in seventeen languages.  He died in Darjeeling while attempting to make a trip to Lhasa in 1842 and a memorial was erected in his honour by the Asiatic Society of Bengal. Akhund Mullah Mohammad Kashani, known as lunar tiles in 1833 was born in Kashan.  In place of his birth date and age of his birth is not mentioned during the 84 years of his life, to guess.

Purdie is believed to have been born in Scotland by 1743; however, his exact birth date and exact place of birth are unknown.  He was trained at an early age in the skills of printing in his motherland.  His immigration to the American British colonies is not known for sure; however, by 1764 he took up residence in colonial Williamsburg, Virginia.  At that time he was employed by the then current Williamsburg printer Joseph Royle, as an apprentice. The Scandinavian electro-pop scene kickstarted with the invention of the Nordik Beat sound in Stockholm in the late 1980s.  By merging the new technologies at the time, building small inexpensive studios armed with computers and samplers rather than traditional instruments and studio equipment, and the latest dance music trends (house, techno, hip-hop, electro, etc.) with the Scandinavian focus since ABBA on mixing strong pop melodies with catchy hooks, both a new sound and a new way of making music were born.  A commonly recognized birth date for the movement has become the October 1987 cover story of ID Magazine in the UK, a cover graced by the first international Afro-Scandinavian pop star, La Camilla from Army of Lovers, as the face of the brand new Nordik Beat movement. Charles Milles Manson (born Charles Milles Maddox, November 12, 1934) is an American convicted mass murderer and former cult leader who led what became known as the Manson Family, a quasi-commune that arose in California in the late 1960s.  Manson's followers committed a series of nine murders at four locations in July and August 1969.  In 1971 he was found guilty of first-degree murder and conspiracy to commit murder for the deaths of seven people – most notably of the actress Sharon Tate – all of which were carried out by members of the group at his instruction.  Manson also received first-degree murder convictions for two other deaths.  Manson was originally sentenced to death, but his sentence was commuted to life imprisonment when California invalidated the state's death penalty statute in 1972.  He is currently serving multiple life sentences at California State Prison in Corcoran.
