Physicist invents new calendar

A US physicist has come up with a new calendar in which every date falls on the same day of the week each year.

The current calendar runs for 365 days which does not divide by seven so dates fall on differents days each year.

Dick Henry, a physicist in Baltimore, Maryland, designed a calendar that uses 364 days, which breaks down evenly into 52 weeks, reports New Scientist.

In his so called Calendar-and-Time plan, March, June, September, and December each contain 31 days, while the other months all get 30.

Christmas Day always falls on a Sunday - but people born on extinct dates such as January 31 would lose their birthdays.

To keep the calendar in synchronisation with the seasons, Henry added an extra week - which is not part of any month - every five or six years.

He named the addition Newton Week in honour of his favourite physicist, Isaac Newton.

"I think such a calendar would be extremely useful," says Owen Gingerich, an astronomer and historian of science at Harvard University.

He said the world was slow to adopt the Gregorian calendar. England did not switch to the system until 1752, nearly 200 years after Rome began using it.
