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 year is a leap year if it is divisible by 4, but century years are not leap years unless they are divisible by 400. (So, the years 1700, 1800, and 1900 were not leap years, but the year 2000 was.) Non-leap years begin and end on the same day of the week. Leap years have 366 days, rather than the usual 365. When is the Next Leap Year?
