A day is a unit of time, commonly defined as an interval equal to 24 hours. It also can mean that portion of the full day during which a location is illuminated by the light of the sun, also known as daytime. The period of time measured from local noon to the following local noon is called a solar day.

Several definitions of this universal human concept are used according to context, need and convenience. In 1967, the second was redefined in terms of the wavelength of light, and it became the SI base unit of time. The unit of measurement for time called "day", redefined in 1967 as 86,400 SI seconds and symbolized d, is not an SI unit, but it is accepted for use with SI. A civil day is usually also 86,400 seconds, plus or minus a possible leap second in Coordinated Universal Time UTC, and, in some locations, occasionally plus or minus an hour when changing from or to daylight saving time. The word day may also refer to a day of the week or to a calendar date, as in answer to the question "On which day?" Day also refers to the part of the day that is not night — also known as 'daytime'. The life patterns of humans and many other species are related to Earth's solar day and the cycle of day and night (see circadian rhythms).

One of the most popular and influential stars in the United States during her lifetime, with one of Hollywood's longest careers, especially on television, Ball began acting in the 1930s, becoming both a radio actress and B-movie star in the 1940s, and then a television star during the 1950s. She was still making films in the 1960s and 1970s. In 1962, Ball became the first woman to run a major television studio, Desilu, which produced many successful and popular television series.

Ball was nominated for an Emmy Award thirteen times, and won four times. In 1977 Ball was among the first recipients of the Women in Film Crystal Award.

Doris Day (born Doris Mary Ann Kappelhoff, April 3, 1924) is an American actress, singer, and animal rights activist. With an entertainment career that spanned through almost 50 years, Day started her career as a big band singer in 1939, but only began to be noticed after her first hit recording, "Sentimental Journey", in 1945. After leaving the Les Brown & His Band of Renown to try a solo career, she started her long-lasting partnership with Columbia Records, which would remain her only recording label. The contract lasted from 1947 to 1967, and included more than 650 recordings, making Day one of the most popular and acclaimed singers of the 20th century. In 1948, after being persuaded by Sammy Cahn, Jule Styne and her agent at the time, Al Levy, she auditioned for Michael Curtiz, which led to her being cast in the female lead role in Romance on the High Seas.

With a legendary Hollywood "girl next door" image, and capable of delivering comedy and romance as well as heavy drama, she appeared in 39 films, released 29 albums, spent 460 weeks in the Top 40 charts and eventually became one of America's most beloved entertainers. She received an Academy Award nomination for her performance in Pillow Talk, won three Henrietta Awards (World Film Favorite), a Grammy Lifetime Achievement Award, Presidential Medal of Freedom, Legend Award from the Society of Singers, Los Angeles Film Critics Association's Career Achievement Award and, in 1989, received the Cecil B. DeMille Award for lifetime achievement in motion pictures.

Lucille Nelson Hegamin (November 29, 1894 – March 1, 1970) was an American singer and entertainer, and a pioneer African American blues recording artist.

Hegamin was born as Lucille Nelson in Macon, Georgia, United States. From an early age she sang in local church choirs. By the age of 15 she was touring the US South with the Leonard Harper Minstrel Stock Company. In 1914 she settled in Chicago, Illinois, where, often billed as "The Georgia Peach", she worked with Tony Jackson and Jelly Roll Morton before marrying pianist, Bill Hegamin. She later told a biographer: "I was a cabaret artist in those days, and never had to play theatres, and I sang everything from blues to popular songs, in a jazz style. I think I can say without bragging that I made the "St. Louis Blues" popular in Chicago; this was one of my feature numbers." Lucille Hegamin's stylistic influences included Annette Hanshaw and Ruth Etting.

The Hegamins moved to Los Angeles, California in 1918, then to New York City the following year. Bill Hegamin led his wife's accompanying band, called the Blue Flame Syncopators; Jimmy Wade was a member of this ensemble.
