This year,2024,is a leap year (闰年).February 29 is known as "leap day".But what is behind this (1)s pecial day? Everyone knows the Earth(2)t ravels around the sun in 365 days.Well,that is not(3)e xactly correct.In fact,it takes a little more:365 days,five hours,forty-...
However, the Gregoriancalendar has only 365 days in a year. If we didn't add a leap day on February 29 almost every four years, each calendar year would begin about 6 hours earlier in relation to Earth's revolution around the Sun (see illustration). As a consequence, our time reckoningw...
根据“However, a leap day is not added every four years. That would lengthen the calendar by 44 minutes, say experts.”可知,闰日并不是每四年增加一次,每四年增加一次的话,会使日历延长44分钟,因此that指代的是“每四年增加一天”。故选A。5.主旨大意题。根据“Another main concern for leap day ...
Generally, a leap year happens every 4 years, which, thankfully, is a relatively simple pattern to remember. However, there is a little more to it than that. Here are the rules of leap years: A year may be a leap year if it is evenly divisible by 4. Years divisible by 100 (centur...
Leap Year Rules To get even closer to the actual number, every 100 years is not a leap year, but every 400 years is a leap year. That brings the average length of the year to 365.2425 days, which is very close to the actual number. Putting all of these rules together, you can se...

2024 is a leap year. February 29 is known as the "leap day". But what is behind this special day?Everyone knows the earth takes 365 days to travel around the sun.Well, that is not exactly correct. The earth really takes 365 days, 5hours, 48 minutes and 46 seconds to complete its ...
So a leap day is added nearly every four years, but not in years including 1700, 1800 and 1900. 因此,几乎每四年会增加一个闰日,但1700年、1800年和1900年除外。 There was a leap day in 2000 because it was a year divisible by both 100 and 400. 2000年有闰日,因为这一年既可以被100也可以...
