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.
The history of leap year. When Julius Caesar introduced the Julian calendar in 46 BC, it had 365 days with 366 every fourth year. That calendar, however, gave February 30 days and August 29. Under Julius Caesar, February had 30 days and the month named after him - July - had 31.
