February is named after the Latin term februum, meaning purification. February was originally the last month of the calendar. It became the second around 450 BC. February is the intercalary month; the month when leap days, weeks or months are added to seasonally adjust the calendar or sync a calendar to moon phases.

- Feb 2: Ground Hog Day; Ground Hog Day is a cross-quarter day. Cross-quarter days happen mid-season or midway between the solstices and equinoxes. Other cross-quarter days are Halloween, May Day (in the US Memorial Day) and Lammas Day (August 1). These days mark the time when seasonal changes start to become noticeable. After Ground Hog Day we can expect more spring like weather than winter weather. These “holidays” are pagan in origin, and have a fascinating history.
