February is the second and shortest month of the year in the Julian and Gregorian calendar with 28 days in common years and 29 days in leap years, with the quadrennial 29th day being called the leap day. It is the first of five months to have a length of less than 31 days (the other four months that fall under this category are: April, June, September, and November), and the only month to have a length of less than 30 days, as the other eleven months have a length of at least 30 days. This year February has 28 days in it.
February is pronounced either as i/ (listen)FEB-yoo-err-ee or i/ FEB-roo-err-ee. Many people pronounce the first "r" as j/ rather than r/, as if it were spelled "Febuary". This comes about by analogy with "January" (i/ (listen)), as well as by a dissimilation effect whereby having two "r"s close to each other causes one to change for ease of pronunciation.
