Leap year facts

Leap years - also known as intercalary or bissextile years - exist to keep each year co-ordinated with the sun's position.

A complete revolution around the sun takes about 365 days and six hours, so every four years an extra 24 hours is built up.

A 'leapling' is the name given to a person born in a leap year on February 29. Leaplings tend to celebrate their birthdays on February 28 or March 1.

In England and Wales people born on February 29 turn 18 and legally become adults on February 28.

In the Gilbert and Sullivan operetta The Pirates of Penzance the character Frederic, born on February 29, had to be a pirate apprentice until he was 21, so, with his missed birthdays, that stretched to the age of 84.

Notable leap year babies throughout history include Pope Paul III (born 1468); Italian composer Gioacchino Rossini, who wrote the William Tell Overture (born 1792); English actor Joss Ackland (born 1928); American rapper Ja Rule (born 1976); and Crystal Palace midfielder Darren Ambrose (born 1984).

Paul added: "We will celebrate this February 29 together with a meal with our partners, but the big party is when we become 60, as what would be only be our 15th birthday.

"Usually, though, our birthdays are just another day and in other years we mark them on February 28."

"It amuses me that I drive a car, have been married twice and have three children when I am on paper just turning 14."

But one woman is celebrating turning the ripe old age of 19!

Herbrie Wirt was born on February 29, 1936, and should be celebrating her 76th birthday.

But thanks to the quirks of the leap year, she is officially still just a teenager.

Speaking about her upcoming birthday, Herbrie, who lives in Jemmett Road, South Ashford, said: "I usually celebrate my birthday on March 1.

"My father was Welsh and I'm very proud of my roots, so what better day to celebrate than St David's Day."

Herbrie will be celebrating with her five children, six step-children, fourteen grandchildren and six great-grandchildren.
