The names of the days of the week and months of the year are derived from those of pagan gods and goddesses — fallen angels, their human wives and their offspring, Nephilim/demons (see Pagan gods and Aliens are Demons!).
Sunday: The name comes from Latin dies solis, meaning ‘day of the sun’, a pagan Roman holiday. Satan is worshipped as the sun god.
Monday: The name comes from the Anglo-Saxon monandaeg, the ‘moon’s day’, and was sacred to the Moon goddess, Astarte.
Tuesday: Tiw’s (Tiu) day. Tiu is the English/Germanic god of War and the Sky; he is identified with the Norse god Tyr. Mars is the Roman god of War. Ares is the Greek god of War.
Wednesday: The day was named to honour the god Anglo-Saxon/Teutonic god Woden or Wodan, leader of the wild hunt; he is identified with Odin, Norse god of War and Death.
Thursday: The day named after Thor, Norse god of Fire and Lightning; he is identified with the Roman god Jupiter, noted for creating thunder and lightning, and Shango, the Yoruba of Nigeria’s god of Thunder and Lightning. In Old Norse, this day is called Torsdag.
Friday: The day in honour of Frigga, Norse goddess of Love and the Heavens.
Saturday: This day was called Sartuni, ‘Saturn’s day’ by the ancient Romans in honour of Saturn, Roman and Italic god of Agriculture. In Anglo-Saxon: sater daeg.
(Songs named after days of the week are in praise of these gods and goddesses, such as Thursday by Pet Shop Boys, Last Friday Night (T.G.I.F.) by Katy Perry, 7 Days by Craig David, Manic Monday by Bangles, Wednesday Lover by The Gap Band, etc.)

March is named after Mars, the Roman god of War.
April is named after Aphrodite, the Greek goddess of Love and Beauty; she is identified with the Roman goddess Venus.

The names of the months of the Jewish calendar were adopted during the time of Ezra, after the return from the Babylonian exile. These names are actually Babylonian month names, brought back to Israel by returning exiles. Note that much of the Scripture refers to months by number, not by name, as pre-Babylonian exile the months of the year were numbered rather than named, and numbering began in spring. The names come from the Babylonian names by way of Akkadian. Akkadian was the common language of the Ancient Near East, and Babylonian was actually a variant of Akkadian, which was used in the Ancient Near East for some 2000 years until it was replaced as the common language by Aramaic with the rise of the Persian Empire about 3000 years ago.
Babylonian: Nisanu — First, refers both to the month as the first month of the year and to the presiding god, Bel. Bel, known as Baal in Israel is not really a name but a title. It means ‘lord’, and also refers to Marduk in Babylonian, and later Persian, pantheon (see The Great Deception).
The word Baal simply means Lord, as is shown in Unger’s Bible Dictionary, p. 665:
Lord (Hebrew Adon), an early word denoting ownership; hence, absolute control. It is not properly a (righteous) title… master; of kings, as the lords of their subjects. (4.) Lord. Master, (Greek Kurios) Supreme… (5.) Baal (Master) (As noted above it means Lord) — applied only to heathen deities (gods), or to man as husband, etc…
Baal: Common Canaanite word for master, lord, was one of the chief main deities of the Canaanite Pantheon, now well known from the religious epic literature discovered at Ras Shamra (an Ugarit of the Amarna Letters) from 1921-1937. — Unger’s Bible Dictionary p. 413
Babylonian: Aru/Ayaru — Bull or herd, prosperity. Presided over by Ea, the Babylonian name for the Sumerian god Enki, the god of Life. Originally the god of Water, Enki is often depicted with the Tigris and Euphrates rivers flowing from his shoulders.
Babylonian: Simanu — Brick-making. Presided over by Sin, the god of the Moon, after the conflation of the Semitic god Sin with the Sumerian god Nanna.
Babylonian: Dumuzu — Babylonian name of the god known in Hebrew as Tammuz; Babylonian, Assyrian and Sumerian god of Fertility, also the god of Vegetation and later of the Sun.
Babylonian: Abu, god of Plants.
Ellul was originally ‘Ululu’ in Babylonian and Elulu in Akaddian. It comes from a root meaning ‘harvest’ and also refers to the mission of the reigning deity of the month, Ishtar, who was the Babylonian Fertility goddess, and shared a similar sounding name and near-identical story and powers with the Egyptian goddess Isis, and the Semitic Astarte (see Pagan feasts).
Babylonian: Tashritu — Beginning. The beginning of the second half-year of the Babylonian calendar. Presided over by Shamash, the Mesopotamian god of the Sun and the likely origin of the Hebrew word shemesh.
Babylonian: Arachsamna — Presided over by Marduk, patron deity of Babylon.
Babylonian: Kislimu (meaning uncertain). Presided over by Nergal, a god of the Sun as it appears during specific times of the day and of the year.
