The name leap year probably comes from the fact that while a fixed date in the Gregorian calendar normally advances one day of the week from one year to the next, the day of the week in the 12 months following the leap day (from March 1 through February 28 of the following year) will advance two days due to the extra day (thus leaping over one of the days in the week).
DEFINITION of 'Return'. The gain or loss of a security in a particular period. The return consists of the income and the capital gains relative on an investment. It is usually quoted as a percentage.
For the term in meteorology, see Invest (meteorology). To invest is to allocate money (or sometimes another resource, such as time) in the expectation of some benefit in the future. In finance, the benefit from investment is called a return. The return may consist of capital gain or investment income, including dividends, interest, rental income etc., or a combination of the two. The projected economic return is the appropriately discounted value of the future returns.
