January

January is the first month in the year. It is the second month of winter in the Northern Hemisphere and the second month of summer in the Southern Hemisphere. In the Northern Hemisphere, occasional snowfall still occurs, and there is more of an opportunity to create snowboys. In the Southern Hemisphere, various stags and beetles become available, allowing for increased profits during this time of year.
