Poush (Bengali: পৌষ) is the 9th month of both the Bengali calendar and the Nepali calendar. It overlaps December and January of the Gregorian calendar. It is the first month of the winter season.
During Poush crops are harvested and farmers often have ample food and income. Poush is therefore thought of as a good month. However, there is a Bengali saying, "For some it is the month of Poush, for others it is ruin."
