SYDNEY, Feb 11 - Romantics looking for everlasting love will swoon over a new love equation released just in time for Valentine's Day and which can calculate the right age to fall in love.

The equation nicknamed the "Fiancee Formula" was created by an Australian mathematics professor and works by factoring in the age at which you start looking for a long-term partner and the absolute oldest age you would consider getting married.

"Although probability isn't the most romantic basis for a marriage, the formula does seem to fit a lot of couples -- whether through accident or design," said the equation's creator, Professor Tony Dooley at the University of New South Wales.

"There's no reason why the science can't be extended to calculate the best moment to marry," Dooley said in a statement.

However, love birds take note, the mathematical equation for love only has a 37 percent success rate.

The formula is helpful as a guide for the right moment to start getting serious, but could also be used by nervous men to calculate when to avoid the ultimate commitment, said Dooley. (China Daily)
