Itching or irritation anywhere on the body can cause discomfort. But when it occurs in an area as sensitive as the vagina and vulva (the labia, clitoris, and vaginal opening), it can be especially uncomfortable. Most genital itching and irritation isn't a major concern. But because they can be symptoms of an infection, it's always a good idea to call your health care provider.
February 29 is a date that usually occurs every four years, and is called leap day. This day is added to the calendar in leap years as a corrective measure, because the Earth does not orbit the sun in precisely 365 days. The Gregorian calendar is a modification of the Julian calendar first used by the Romans.
A leap year is a calendar year containing one additional day added to keep the calendar year synchronized with the astronomical or seasonal year. Because seasons and astronomical events do not repeat in a whole number of days, calendars that have the same number of days in each year drift over time with respect to the event that the year is supposed to track. By inserting an additional day or month into the year, the drift can be corrected. A year that is not a leap year is called a common year. For example, in the Gregorian calendar, each leap year has 366 days instead of the usual 365, by extending February to 29 days rather than the common 28.
