Jûnius "Month of Juno," from Juno (Genitive Junonis) "the Youthful" (goddess), originally an old Etruscan (and Italic) goddess of birth. (Later identified with the Greek queen of the gods, the goddess Hera.)

"Month of Jûlius (Caesar)," from Jûlius (Genitive Jûlii), the name of a patrician clan (gens) which included the family of the Caesars (Caesares), whence sprang Gâjus Jûlius Caesar, after whom the month of Quîntîlis (earlier Quînctîlis from quînque, "5") was renamed.
Augustus (Originally Sextîlis ,"Sixth [month]," from sex, "6," and the death month of the emperor Octâviânus.)  "Month of Augustus (Caesar)," from augustus "sacrosanct;  august, majestic"; and as a title, "(His) August Majesty," honorific title given to Gâjus Jûlius Caesar Octâviânus (originally only Gâjus Octâvius), the adopted son of Gâjus Jûlius Caesar.  Octâviânus was the first Roman emperor (31 B.C.-A.D. 14).

Weekday Names

Weekday Derivation (through Old English from the names of the Greek and Latin "planet gods")
Sunday Day of the Sun (The Germanic word "sun" was originally feminine;  hence not "Sunsday").  Symbol:  sacred draught animal = the stallion drawing a plough.  Translation of Latin Solis diês, "day of the Sun."  (French dimanche and Spanish domingo come from Christian Latin [diês] dominicus, "[the day] of the Lord," not from the older, pagan Latin as do the other weekday names.)  The Latin name is itself a loan translation from Greek hëméra Hëlíou, "day of the Sun [god]."
Monday Day of the Moon (The Germanic word "moon" was originally feminine;  hence not "Moonsday"), translation of Latin Lunae diês, "day of the Moon" (cf. French lundi, Spanish lunes).  Symbol:  lunar crescent.  The Latin name is itself a loan translation from Greek hëméra Selênës, "day of the Moon [goddess]."
Tuesday Day of Tew (Germanic, originally masculine;  Old Norse Tyr, Old High German Ziu).  Symbol:  the rune for "T" (į, an upward-pointing arrow), the warrior rune.  Translation of Latin Mârtis diês, "day of Mars" (cf. French mardi, Spanish martes).  The Latin name is itself a loan translation from Greek Areôs hëméra, "Ares' day."  (Ares was the god of war and slaughter, strife and pestilence.)
Wednesday Day of Woden (Germanic, originally masculine;  Old Norse Odin, Old High German Wotan).  Symbols:  eagle, raven (carrion birds, birds of death), whirling disk (i.e., the birth canal and the tunnel of death), the wal knot (intertwined triple triangle), spear.  (The name Woden itself comes from Gothic Wodan-, Wodin-, which is composed of wod-, "in shamanic trance," and the ending "-an-" or "-in-," which mean "chief or leader of."  Thus the name means "Leader of those in shamanic rapture," or, more simply, "Chief of the Shamans" or "Shaman God."  Ancient Germanic religion was shamanic.)  The word translates Latin Mercuriî diês "day of Mercury" (cf. French mercredi, Spanish miércoles).  The Latin name is itself a loan translation from Greek Hermoû hëméra, "Hermës' day." (Hermës was the messenger of the gods to men, and the one who, like the shaman-god Wodan, conducted the souls of the dead to the Netherworld;  he was also the god of commerce and travel.)
Þursday Day of Thor (= Thunder).  (The Germanic word was originally masculine;  Old Norse Thor, Old High German Donar).  Symbols:  great oaks, ax, hammer, swastika.  Translation of Latin Jovis diês "day of Jove" (the high god).  (Cf. French jeudi, Spanish jueves).  The Latin name is itself a loan translation of Greek Diós hëméra "Zeus' day."
Friday Day of Fry, the goddess of love (originally feminine, hence not "Frisday";  Old Norse Frigga, Old High German Frija;  cf. also English fri-end "loving person").  Symbols:  nuts, apples, seeds, wheat;  boar & sow, mare.  Translation of Latin Veneris diês "day of Venus" (cf. French vendredi, Spanish viernes).  The Latin name is itself a loan translation from Greek Aphrodítës hëméra, "Aphrodítë's day."
Saturday Day of Saturn (originally a Latin, not Germanic, masculine;  hence not "Satursday").  Symbols:  plough, scythe/sickle, snake biting its own tail, i.e., symbols of all-consuming time (= the "Grim Reaper").  English follows the Latin Sâturnî diês "day of Saturn".  The Latin name is itself a loan translation from Greek Krónou hëméra "Krónos' day."  By contrast, Aramaic-Hebrew shabbâþ (from Hebrew shâbháþ "to rest") produced Greek Christian sábbaton (Dative sabbátôj, "on the Sabbath"), which passed into classical Arian Christian Visigothic as sabbatô "Sabbath."  In vulgar Greek the word was "smoothed out" to sámbatôn and taken into later Gothic as sambatô.  Arian Christian Germanic missionaries took the word northwestward into Germanic territory. There it was suffixed with the clarifying word dags "day" (i.e., yielding something like *sambatadags) and ultimately resulted in modern French samedi, (but cf. Spanish sábado), Old High German sambaztag and modern German Samstag, which competes with true German Sonnabend "Eve of Sun(day)."  The closest Germanic equivalent to Sâturnus may have been the terrifying supernatural monster known in the north as Loki (whom the Christian Saxo Grammaticus, around 1200, demonized as "Loki of the Outer Regions" [Útgarša Loki]), but the "neutral," foreign name of Saturday was preferred by Englishmen to *Lokisday (which the Scandinavians apparently changed into Laugardagr "Bathing day"; laug- = English lye, the original form of soap).

Note: The year of twelve non-lunar months as we know it originally started with the year 45 B.C. by decree of Julius Caesar (whence the "Julian" calendar).  He adapted it from the twelve-month Egyptian solar calendar, which itself actually began with the rising of the "dog star," Sirius (in the "dog days" [diês canîculârês] of July 23 to August 23).  The Egyptian calendar's twelve months each had 30 days, and at the end of the year were added five days (six, in leap years) to make a total of 365 (or 366) days.  Julius Caesar took the extra five or six days and distributed them among the twelve months.  At that time the months of Quîntîlis and Sextîlis had only 30 days apiece.  Later, in slavish political adulation of Caesar, the Roman Senate not only changed the name of the month Quîntîlis to Jûlius, but took a day away from Februârius, which had 30, and appended it to the then-30-day-long month of Jûlius, thus making his month equal to those with 31 days.  Later, the Senate repeated this action in the case of Jûlius' nephew, Augustus Caesar, taking yet another day away from the "unimportant" month of Februârius and adding it to the month of Augustus, which it had newly renamed from Sextîlis.  Thus it came about that today February has only 28 days normally and 29 in leap years.

Before Caesar's decree, the Roman year had had only 10 months, beginning with March, and the days between December and March had not been organized into separate months.  (They had been merely a time of winter quiescence and religious festivals.)  The "Gregorian" calendar was a small but important correction of the Julian calendar made in 1582 by the astronomers of Pope Gregory XIII.  And, finally, the week is an approximate quarter of the lunar cycle of 27.3 days.  (It has no provable historical connection with the Hebrew mythology expressed in the first chapter of the biblical book of Genesis.)
