MONTHS
Roman god of beginnings and endings. He is usually represented with two heads, one facing backward, the other facing forward. Janus symbolizes the principle of looking back to the past to understand the present in order to 
shape the future
In ancient mythology, the treasures of the gods were protected by JANUS, the "Keeper of Keys", and "Custodian of Treasures". Looking both forward and back, this ancient figure could see in all directions, preserving and protecting all that was important.

February derives from the Latin term
"februa" which means "goat skin!"
Goats were sacred to Dionysius, the god of wine.  This month was named after Februalia, a time period when sacrifices were made to atone for sins.  
Goats were sacrificed and their hides 
cut into strips called "februa". 
Some sources say the Lupercalia rites also included a game that allowed boys to pick, from an urn or box, the names of girls written on a piece of paper. These pairings were supposed to be sweethearts for one year, beginning in March. Some experts also say that the smaller festival of Juno Februata, the goddess of love's fever, was conjoined to rites of the Lupercalia.
 Twin themes of purification and fertility come together in the Roman holiday called Lupercalia. Priests (luperci) of two colleges (Quintilii and Fabii) met at the cave where the she-wolf supposedly nursed the founding twins Romulus and Remus. Vestal Virgins offered their holy salt cakes. Priests sacrificed a dog and a goat, and smeared the animal blood on two boys who, clad only in a bit of goatskin, later led a band of revelers (luperci) whose antics included striking bystanders with a goatskin strip (februa). Women so struck -- even barren ones -- were thought to become fertile. The priests may also have paired up youth of both sexes who were to stay paired up for the remainder of the year.
In the Latin era, February was a big month for festivals. Ovid says the name of the month, February, is derived from `februum' in Latin, meaning purification or “anything according by which the soul was purged”; for the ancients, the month was also a major time of honoring the dead through rituals. These rituals were called the Februalia.
There was an important Roman event in February called the Lupercalia, held in honor of Faunus Lupercus, a benevolent god who protected sheep. The Festival of Lupercalia, which culminated with a parade on February 15, is a factor in the development of Valentine's Day, according to some sources. The Lupercalia festivities involved purification rituals, sacrifice, and ritual striking of women with leather thongs [februa]--to encourage fertility. 



March was named after Mars, the god of war.
Mars, the god of war, has given his name to the month of March, for the Romans considered it a noisy, blustering month. The Romans thought that Mars could do almost anything because he was so strong. When they went to war, they carried a cage full of chickens sacred to Mars. Before the battle they offered corn to the chickens. Breathlessly, the Roman soldiers awaited the result. If the birds rejected the corn, they feared defeat. If they ate it, the Romans felt confident of victory.
Mars was to the Romans a terrifying and mighty warrior who dashed round in a chariot drawn by two horses, whose names were "Terror and Flight". He held aloft a burnished shield and brandished a long spear. The Romans feared him greatly, for they said that, when Mars raised his head, flashes of lightning and thunder played round his head.
The Church of Rome did not have any objection against this name and allowed it to continue in the Christian calendar. Therefore, March continued to be the third month of the Gregorian calendar.
Romans named him after Ares, the Greek god of war.  Romans considered Mars the father of Romulus and Remus, the legendary founders of Rome

The Greek goddess Aprhodite became the Roman goddess Venus

 April is said to be named after Aprilis (Aphrodite) by the Roman poet Ovid. Others say that aprilis comes from the Latin word "aperio" (to open) since this was the month that fruits and flowers blossomed.
It was a time for several agricultural festivals. In it they sacrifice to Venus (Aphrodite), and the women bathed on the calends (where the word "calendar" comes from), or first day of the month – the new moon, with myrtle garlands on their heads.
