leap year

Which year were you born? Is it the leap year?(你出生在哪年，是闰年吗？)

Leap year recurs every four years, and in that year February have 29days.(闰年每四年一次，在闰年的那一年，二月份只有29天。)

How often is there a leap year?(隔多长时间有一次闰年？)

And regardless of the calendar days of 2011, what lies ahead of you is indeed a leap year!(不管2011年接下来的日程会怎样，你们现处的年份确实是跃变的一年！)

Feb. 29 is an intercalary day; leap year is an intercalary year.(2月29日是闰日；闰年是有添加日的年份。)

This recurring appointment begins on a leap year.(此定期约会开始于闰年。)

Leap year recurs every four years.(每四年闰年一次。)

The leap year comes around once in four years.(闰年每四年来一次[每四年有一个闰年]。)

If you ignore 1900, you can figure out if a given year is a leap year just by looking to see if the rightmost two bits are zero.(如果你忽略1900年，你就可以通过观察最右边的两位是否都为零来判断某一年是否为闰年。)

There are other tricks to assist with dates in the first months of the year—for example, the last day of February is always an anchor day, leap year or no.(还有一些其他技巧可以帮助你确定一年的头几个月的日期——例如，二月的最后一天总是锚日，不管闰年还是平年。)
