According to Wikipedia, January is the first month of the year in the Julian and Gregorian calendars, and one of seven Gregorian months with the length of 31 days. The first day of the month is known as New Year’s Day. It is, on average, the coldest month of the year within most of the Northern Hemisphere (where it is the second month of winter) and the warmest month of the year within most of the Southern Hemisphere (where it is the second month of summer). In the Southern Hemisphere, January is the seasonal equivalent of July in the Northern Hemisphere.
January starts on the same day of the week as October in common years, and starts on the same day of the week as April and July in leap years. In a common year, January ends on the same day of the week as February and October, and ends on the same day of the week as July in a leap year.
