Christmas tree
Christmas treeLilit SahakyanA Christmas tree is traditionally an evergreen conifer decorated with lights and ornaments that is associated with Christmas celebrations. The modern Christmas tree tradition began in 16th century Germany when devout Christians brought decorated trees into their homes and decorated them. By the 19th century, Christmas trees had spread beyond Germany and became popular among the upper classes in other parts of Europe and beyond. Today, Christmas trees are a widely celebrated symbol of Christmas in many Western Christian cultures.
Santa Claus
Santa ClausLilit SahakyanSanta Claus originated from Christian traditions surrounding Saint Nicholas, a 4th century Greek bishop known for gift-giving. Over time, the legend of Santa merged with figures like Father Christmas from England and Sinterklaas from the Netherlands. Santa is now commonly depicted as a portly, joyous man in red with white fur trimmings who brings gifts on Christmas Eve. He lives at the North Pole making toys with elves and travels with reindeer to deliver presents worldwide in a single night. The modern image of Santa was largely popularized in the 19th century through poems, stories, and illustrations.
Earth
EarthLilit SahakyanThe Moon is a relatively large, terrestrial, planet-like natural satellite, with a diameter about one-quarter of Earth's. It is the largest moon in the Solar System relative to the size of its planet, although Charon is larger relative to the dwarf planet Pluto. The natural satellites of other planets are also referred to as "moons", after Earth's.
The gravitational attraction between Earth and the Moon causes tides on Earth. The same effect on the Moon has led to its tidal locking: its rotation period is the same as the time it takes to orbit Earth. As a result, it always presents the same face to the planet. As the Moon orbits Earth, different parts of its face are illuminated by the Sun, leading to the lunar phases; the dark part of the face is separated from the light part by the solar terminator.

Due to their tidal interaction, the Moon recedes from Earth at the rate of approximately 38 mm/yr. Over millions of years, these tiny modifications—and the lengthening of Earth's day by about 23 µs/yr—add up to significant changes.[221] During the Devonian period, for example, (approximately 410 Mya) there were 400 days in a year, with each day lasting 21.8 hours.[222]
The Moon may have dramatically affected the development of life by moderating the planet's climate. Paleontological evidence and computer simulations show that Earth's axial tilt is stabilized by tidal interactions with the Moon.[28] Some theorists think that without this stabilization against the torques applied by the Sun and planets to Earth's equatorial bulge, the rotational axis might be chaotically unstable, exhibiting chaotic changes over millions of years, as appears to be the case for Mars.[223]
Viewed from Earth, the Moon is just far enough away to have almost the same apparent-sized disk as the Sun. The angular size (or solid angle) of these two bodies match because, although the Sun's diameter is about 400 times as large as the Moon's, it is also 400 times more distant.[186] This allows total and annular solar eclipses to occur on Earth.
The most widely accepted theory of the Moon's origin, the giant-impact hypothesis, states that it formed from the collision of a Mars-size protoplanet called Theia with the early Earth. This hypothesis explains (among other things) the Moon's relative lack of iron and volatile elements and the fact that its composition is nearly identical to that of Earth's crust.[224]
Mkhitar sebastatsi
Mkhitar sebastatsiLilit SahakyanMkhitar Sebastatsi was an Armenian Catholic Church figure and Armenologist born in 1676 in Sebastia who founded the Mekhitarist Congregation. He studied at various monasteries in Armenia before traveling to Aleppo in 1693 where he met Catholic missionaries and was ordained a priest. In 1701, he founded the Mekhitarist Congregation in Constantinople and in 1705 obtained approval to build a monastery in Athens. He moved the congregation to Venice in 1715 to escape Turkish attacks. On St. Lazarus Island, he opened a school, translated works, and published books to educate Armenians while directing philological research. He died in 1749 having enriched Armenian

My name
My nameLilit SahakyanMariam is the Aramaic form of the biblical name Miriam, notably the name of Mary the mother of Jesus. The name originated from Egyptian or Hebrew roots and has been translated and interpreted in various ways over time. Modern given names derived from Maryam/Mariam are extremely frequent in Christian culture and also used in some Islamic cultures due to the Quranic tradition of Mary. There are many spelling variants of the name that have been adopted worldwide in different languages and traditions.
Teachers day
Teachers dayLilit SahakyanThis document discusses Teachers' Day, including its origins in the 19th century to honor important educators, and how it is celebrated on different dates by different countries. Twenty-one countries celebrate Teachers' Day on October 5th, while eleven countries celebrate it on February 28th. The document also notes that Armenia previously celebrated Teachers' Day on the first Sunday of October but changed it to October 5th, and provides examples of dates and honorees for specific countries like Argentina and India. It concludes with the writer expressing love and appreciation for their Armenian and English teachers.
12 months of the year
12 months of the yearLilit SahakyanThe document summarizes the origins and histories of the 12 months in the Gregorian calendar. It discusses how each month got its name from Roman gods or meanings in Latin. It also describes how the order and lengths of the months have changed over time, particularly when the Roman calendar was reformed by Numa Pompilius around 700 BCE to add January and February, and again later by Julius Caesar.
