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 year with an extra day-February 29. Leap years occur on years that are exactly divisible by four (with no remainder), with the exception of most century (also called centenary) years. Only century years divisible by 400 are leap years.
