American physicist Dick Henry has invented a new calendar in which every date always falls on the same day of the week from year to year. Christmas Day for example would always fall on a Sunday in this system. Called the Calendar-and-Time Plan, the new calendar involves all months having thirty days, except for March, June, September and December, which would have thirty-one days. To maintain seasons in their proper places, instead of having leap years with an extra day in February, the new calendar adds a week, called “Newton Week”, every five to six years. However, people born on days that are eliminated, such as January 31, would lose their birthdays. Henry hopes to gather enough support to start using the system on January 1, 2006, which is a Sunday in both the old and new calendars.
