Circa (from Latin, meaning "around"), usually abbreviated c. or ca. (also circ. or cca.), means "approximately" in the English language, usually referring to a date. Circa is widely used in genealogy and historical writing when the dates of events are not precisely known.

When used in date ranges, the term "circa" is applied before each approximate date, while dates without "circa" immediately preceding them are generally assumed to be known with certainty.

Examples:

Justin Randall Timberlake (born January 31, 1981) is an American singer, actor, and businessman. He achieved early fame when he appeared as a contestant on Star Search, and went on to star in the Disney Channel television series The New Mickey Mouse Club, where he met future bandmate JC Chasez. Timberlake became famous in the late 1990s as the lead singer and youngest member of the boy band 'N Sync, whose launch was financed by Lou Pearlman.

In 2002, he released his debut solo album, Justified, which sold more than seven million copies worldwide. The album was a commercial success, spawning the hits "Cry Me a River" and "Rock Your Body". Timberlake continued his success with his second solo album, FutureSex/LoveSounds (2006), debuting at number one on the Billboard 200 chart, and produced the US number-one hit singles "SexyBack", "My Love", and "What Goes Around... Comes Around".

Timberlake has won six Grammy Awards and four Emmy Awards. His first two albums made him one of the most commercially successful singers in the world, each selling in excess of 7 million copies. He also has an acting career, having starred in films such as The Social Network, Bad Teacher and Friends with Benefits. His other ventures include record label Tennman Records, fashion label William Rast, and the restaurants Destino and Southern Hospitality.

"A Leela of Her Own" is the sixteenth episode in the third season of the animated series Futurama and is a homage to A League of Their Own directed by Penny Marshall. It originally aired in North America on April 7, 2002. Bob Uecker provided the voice of himself and Tom Kenny provided the voice of Abner Doubledeal.

A new pizza restaurant run by Cygnoids has moved in across the street from the Planet Express building. Leela convinces the others that they should go to greet their new neighbors. They find that the Cygnoids have much to learn about Earth customs. Fry tries to help them get adjusted, first by giving them advice on how not to make pizza (such as not using live bees as an ingredient, not crushing rats to make wine, and not letting their relatives live in the pizza oven when not in use) and then by suggesting that they learn how to play blernsball (the 30th century version of baseball as seen in "Fear of a Bot Planet"). The Planet Express staff and the Cygnoids form teams and go to a blernsball diamond in a nearby park. While playing blernsball with the Cygnoids, Leela's lack of depth perception causes her to injure opposing players by beaning them in the head. Gaining notice from Abner Doubledeal, the owner of the New New York Mets, who thinks that having a one-eyed woman repeatedly bean opposing players would be a good novelty act, she becomes the first female player to play professional blernsball. Leela sees herself as a pioneer for women in sports, but Jackie Anderson, a female star for a college blernsball team, tells her that she is an embarrassment who is making it harder for legitimate female athletes to be taken seriously. Leela is on the fast track to becoming the worst blernsball player ever and seeks help from Hank Aaron XXIV, a distant relative of Hank Aaron, who is currently the worst blernsball player of all time.

Cristiano Ronaldo dos Santos Aveiro,OIH, (born 5 February 1985), commonly known as Cristiano Ronaldo, is a Portuguese footballer who plays as a winger or striker for Spanish La Liga club Real Madrid and is the captain of the Portuguese national team. Ronaldo became the most expensive footballer in history after moving from Manchester United to Real Madrid in a transfer worth £80 million (€93.9 million/$131.6 million). In addition, his contract with Real Madrid, in which he is paid €12 million per year, makes him one of the highest-paid footballers in the world, and his buyout clause is valued at €1 billion as per his contract.

Ronaldo began his career as a youth player for Andorinha, where he played for two years, before moving to C.D. Nacional. In 1997, he made a move to Portuguese giants Sporting Clube de Portugal. Ronaldo's precocious talent caught the attention of Manchester United manager Alex Ferguson, who signed him for £12.24 million (€15 million) in 2003. The following season, Ronaldo won his first club honour, the FA Cup. He also played at Euro 2004 with Portugal and scored his first international goal in the opening game of the tournament against Greece, in addition to helping Portugal reach the final. He was featured in the UEFA Euro All-Star Team of this competition.
