我们得先理解“闰”,以及为什么会引入“闰”这个概念。 Leap yearsexist because while the world follows a 365-day Gregorian calendar, it actually takes the planet a little bit more than a year to orbit the sun. It takes Earth 365 days, 5 hours, 48 minutes and 46 seconds to orbit the sun,...
Later, on a calendar yet to come (we’ll get to it), it was decreed that years divisible by 100 not follow the four-year leap day rule unless they are also divisible by 400, the JPL notes. In the past 500 years, there was no leap day in 1700, 1800 and 1900...
“So adding one day every four years was too much.” Astronomers now know that a solar year is actually 365. 24219 days long. This may not seem like much under the Julian Calendar, but that little mistake led to about 11 minutes off a year. So in 1582, Pope Gregory decided to reset...

和“So, almost every four years an extra day appears on the calendar.”可知,每年有多出的5小时48分46秒,积攒4年就多了一天。故选D。2.细节理解题。根据“There will be leap days in 2028,2032 and 2036.”可知,2036年会有闰日。故选B。3.推理判断题。根据“Over time, that would mean summer ...
Leap day is an extra day that gets added on to the calendar. It’s added to February since it’s already the shortest month of the year. Why does it happen every four years? Leap year occurs every four years due to theEarth’s orbit. While we know that it takes around 365 days fo...
