Why Is 2020 Called a Leap Year?
February 29 comes up on the calendar only every four years. A year with a February 29 might be good news if you are paid by the day or the week. But it might be bad news if you were born on a February 29.____31____.
American English has a term for the unusual situation. February 29 is called a leap day. And the entire 12-month period with a February 29 in it is called a leap year. This year, 2020, is such a year.
In a leap year, the dates jump over one day of the week. Let me explain. In 2017, the last day of the year, December 31, fell on a Sunday. In 2018, it fell on a Monday. In 2019, it fell on a Tuesday. But in 2020, December 31 will fall on a Thursday.___32___.
The reason for a leap day or a leap year is because our calendar does not follow the Earth’s orbit around the sun exactly.___33___. So every four years, we put all that time together into an extra day — or, what is officially called an intercalary(闰) day.
“Leap” is also an important word for two other common American expressions.___34___. If you want someone to investigate a situation completely before taking action, you might say, “Look before you leap.” The other expression is a phrase of hope. Urging someone to “take a leap of faith” means inviting the person to take action, even if not everything about a situation is known. Interestingly, both phrases are completely reasonable to say to someone who is about to get married. On that note, some people choose to marry on February 29 because it is an unusual date.___35___. Leap years were believed to be difficult, and leap days unlucky and a bad time to begin anything new. Whatever you think about them, the change in the calendar will be gone soon enough. Then we can return to normal, and leap over February 29 as usual.
A. One is a kind of warning.
B. That’s why we called it a Leap Year
C. It just leaped right over Wednesday.
D. Each year, we have a little time left over.
E. You have to wait three years in between birthdays!
F. As a verb, the word “leap” means to jump, or to move quickly.
G. Some ancient peoples would likely tell couples not to do it, however.
