<P> February is the third month of meteorological winter in the Northern Hemisphere . In the Southern Hemisphere, February is the last month of summer (the seasonal equivalent of August in the Northern Hemisphere, in meteorological reckoning). </P> <P> February may be pronounced either as (/ ˈfɛbjuːˌɛri / (listen) FEB - ew - err - ee or / ˈfɛbruːˌɛri / FEB - roo - err - ee). Many people pronounce it as (/ juː / (listen) ew rather than / ruː / roo), as if it were spelled "Feb - u-ary". This comes about by analogy with "January" (which ends in "- uary" but not "- ruary"), as well as by a dissimilation effect whereby having two "r" s close to each other causes one to change for ease of pronunciation . </P> <P> The Roman month Februarius was named after the Latin term februum, which means purification, via the purification ritual Februa held on February 15 (full moon) in the old lunar Roman calendar . January and February were the last two months to be added to the Roman calendar, since the Romans originally considered winter a monthless period . They were added by Numa Pompilius about 713 BC . February remained the last month of the calendar year until the time of the decemvirs (c. 450 BC), when it became the second month . At certain intervals February was truncated to 23 or 24 days, and a 27 - day intercalary month, Intercalaris, was inserted immediately after February to realign the year with the seasons . </P> <P> February observances in Ancient Rome include Amburbium (precise date unknown, Sementivae (February 2), Februa (February 13--15), Lupercalia (February 13--15), Parentalia (February 13--22), Quirinalia (February 17), Feralia (February 21), Caristia (February 22), Terminalia (February 23), Regifugium (February 24), and Agonium Martiale (February 27). These days do not correspond to the modern Gregorian calendar . </P>
