Just a little bit of study will show one that the new year (according to Yahweh's calendar in the heavens - Genesis 1:14-18) is not on January 1 - in the dead of winter, but rather in the spring when everything has come to life and is re-birthed. The first month on the Biblical calendar is named Abib (Exodus 12:2; 13:4) meaning "ears of grain." The month name stems from the harvest of barley in the spring-time.The pre-46 B.C. Roman calendar actually had lunar months that began on what was called then the kalends of March or March 1. March 1 then and March 1 now do not coincide because March now is an arbitrary solar month that consists of strictly 31 days. March pre-46 B.C. was a lunar month consisting of either 29 or 30 days depending upon the lunar cycle. The Roman month of "Martias" (March) was the moon that came closest to the spring equinox (which takes place on the current Gregorian calendar on March 20 or 21).
In 46 B.C. Julius Caesar of Rome, under the advice of an astronomer named Sosigenes decided to discard the moon from the Roman calendar and adopt a strictly solar calendar. The reason that January (then Januarius) was chosen to be the first month on the calendar was because it was named after the god Janus, a two faced god of new beginnings. He was the god of gates, doors, births, etc. He had one face to take out the old year and bring in the new.
We should acknowledge and celebrate the beginning of Yahweh's year, not the beginning of a year that is completely out of kilter with nature and dedicated to a pagan, heathen god.
