[00:00.00]Yahoo! it's leap day, 
[00:01.96]that extra day in February that lands on 
[00:04.11]our calendars once every four years.
[00:06.73]It means deals on donuts and fast food,
[00:10.70]it commemorates the life of St Oswald 
[00:12.56]who died about a thousand years ago 
[00:14.66]and was famous for building monasteries.
[00:16.94]We take it, you know about 
[00:19.34]the Earth's annual trip around the sun 
[00:21.43]takes a year right? Well it really takes 
[00:24.97]365 and one quarter days.
[00:28.53]And Year starting to think, come on, 
[00:31.90]no one said anything about math well tough, 
[00:34.22]the trip takes 365 days 5 hours 
[00:38.50]48 minutes and 46 seconds.
[00:40.67]And if we didn't add a day every four years, 
[00:44.50]then after a half dozen centuries or so.
[00:47.28]Summer would turn into winter, 
[00:49.48]and winter would turn into summer, 
[00:51.53]giving a whole new meaning to Christmas in July.
[00:54.99]When the ancient Egyptians began 
[00:56.80]measuring time by dividing the year 
[00:58.86]into 12 months of 30 days.
[01:00.98]They added the five extra days on to 
[01:03.60]the end of the year as five days of festivals, 
[01:06.25]party on Pharaoh.
[01:08.00]But seriously, to be a leap year, 
[01:10.89]the year number must be divisible 
[01:13.70]by four, easy peasy.
[01:15.97]But that 365 day 5 hour and 48 minutes 
[01:21.61]and 46 seconds times 4, only adds up 
[01:25.70]to an extra 23.2 hours, not a full 24.
[01:30.62]So what is a world to do 
[01:32.74]as all those leap days pile up?
[01:35.86]We occasionally take out some leap days, 
[01:39.14]we only get a leap day in end of 
[01:41.75]century years that are divisible by 400 so.
[01:46.00]For instance, the year 2000 was a leap year, 
[01:49.73]but the year 1900 was not. Got it? Me either.
[01:55.38]For all you celebrating February 29th 
[01:58.17]as your birthday, you are special.
[02:00.21]Think of it this way, all the kids you 
[02:02.89]went to school with kids from your grade, 
[02:04.94]when they turn 100, you'll be 25, 
[02:08.35]give or take a couple of minutes.

四年一闰日背后的历史以及它的重要性
