闰rùn一回归年的时间为365天5时48分46秒。阳历把一年定为365天,所余的时间约每四年积累成一天,加在二月里;农历把一年定为354天或355天,所余的时间约每3年积累成一个月,加在一年里。这样的办法,在历法上叫做闰。{intercalary; insert an extra day or month in the calendar. Because a tropical year lasts for 365 days, 5 hours, 48 minutes and 46 seconds, the Gregorian calendar sets the year at 365 days and adds an extra day that equals the total of the surplus time to February of every 4th year, whereas the Chinese lunar calendar sets the year at 354 or 355 days while the surplus time adds up to an extra month that is inserted in every 3rd year.} |
