Saturday
Saturday is the day of the week between Friday and Sunday. No later than the 2nd century, the Romans named Saturday ("Saturn's Day") for the planet Saturn, which controlled the first hour of that day, according to Vettius Valens. The day's name was introduced into West Germanic languages and is recorded in the Low German languages such as Middle Low German , ''saterdach'', Middle Dutch (Modern Dutch ) and Old English , ''Sæterndæġ'' or . Origins Between the 1st and 3rd centuries AD, the Roman Empire gradually replaced the eight-day Roman nundinal cycle with the seven-day week. The astrological order of the days was explained by Vettius Valens and Dio Cassius (and Chaucer gave the same explanation in his '' Treatise on the Astrolabe''). According to these authors, it was a principle of astrology that the heavenly bodies presided, in succession, over the hours of the day. The association of the weekdays with the respective deities is thus indirect, the days are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monday
Monday is the day of the week between Sunday and Tuesday. According to the International Organization for Standardization's ISO 8601 standard, it is the first day of the week and in countries that adopt the "Sunday-first" convention, it is the second day of the week. The name of Monday is derived from Old English ''Mōnandæg'' and Middle English ''Monenday'', originally a translation of Latin ''dies lunae'' "day of the Moon". Names The names of the day of the week were coined in the Roman era, in Greek and Latin, in the case of Monday as ἡμέρᾱ Σελήνης, ''diēs Lūnae'' "day of the Moon". Many languages use terms either directly derived from these names or loan translations based on them. The English noun ''Monday'' derived sometime before 1200 from ''monedæi'', which itself developed from Old English (around 1000) ''mōnandæg'' and ''mōndæg'' (literally meaning "moon's day"), which has cognates in other Germanic languages, including Old Frisian ''mōna ...

Valentine's Day
Valentine's Day, also called Saint Valentine's Day or the Feast of Saint Valentine, is celebrated annually on February 14. It originated as a Christian feast day honoring one or two early Christian martyrs named Saint Valentine and, through later folk traditions, has become a significant cultural, religious, and commercial celebration of romance and love in many regions of the world. There are a number of martyrdom stories associated with various Valentines connected to February 14, including an account of the imprisonment of Saint Valentine of Rome for ministering to Christians persecuted under the Roman Empire in the third century. According to an early tradition, Saint Valentine restored sight to the blind daughter of his jailer. Numerous later additions to the legend have better related it to the theme of love: an 18th-century embellishment to the legend claims he wrote the jailer's daughter a letter signed "Your Valentine" as a farewell before his execution; anoth ...
