This Sunday at 2 a.m. all clocks need to be moved forward one hour for Daylight Savings Time. Here are some interesting facts regarding daylight savings:

• Ben Franklin gets credit for thinking up the idea of daylight saving time.
• In Antarctica, there is no daylight in the winter and months of 24-hour daylight in the summer. But many of the research stations there still observe Daylight Saving Time anyway, to synchronize with their supply stations in Chile or New Zealand.
• While twins born at 11:55 p.m. and 12:05 a.m. may have different birthdays, Daylight Saving Time can change birth order — on paper, anyway. During the time change in the fall, one baby could be born at 1:55 a.m. and the sibling born ten minutes later, at 1:05 a.m. In the spring, there is a gap when no babies are born at all: from 2:00 a.m. to 3:00 a.m.
• Beginning in 2007, Daylight Saving Time commenced on the second Sunday in March and ended on the first Sunday in November.
• Most countries near the equator don’t deviate from standard time.
• In 1916, Germany and its allies were the first countries to use DST as a way to conserve coal during the First World War.
• In 1984, Fortune magazine estimated that a seven-week extension of DST would yield an additional $30 million for 7-Eleven stores, and the National Golf Foundation estimated the extension would increase golf industry revenues $200 million to $300 million.
