Are the festivities of New Year's Eve and New Year's Day that God approves? Since God set the holy calendar for the first month of the year to begin in what we call March or April, it is obviously not God's new year (Exodus 12:2; Deuteronomy 16:1). And for that day, God did not order a celebration either.
New Year's Origin
What's the root of the New Year, then? At the beginning, the ancient Romans gave each other New Year's presents from the branches of holy trees. They gave gold-covered nuts or coins imprinted with images of Janus, the god of gates, doors and beginnings, in later years. January was named after Janus, one looking forward and the other looking backward, who had two faces. Gifts were also brought to the emperor by the Romans. Eventually, the emperors started requesting such presents. But this custom and some other pagan New Year practices in A.D. were outlawed by the Christian church.

Unpleasant to God
New Year's Eve is all too often viewed today as an excuse for drinking too much and lowering moral standards. It is one of the most dangerous times of the year for drunk driving, and warnings about those who shoot weapons into the air in celebration are issued every year, an act that becomes deadly too frequently.
Celebrating the pagan holiday of New Year is not appealing to God for all these reasons.
