### does anyone know when the chinese new year is?

"The Chinese lunar year is divided into 12 months of 29 or 30 days. The calendar is adjusted to the length of the solar year by the addition of extra months at regular intervals. The years are arranged in major cycles of 60 years. Each successive year is named after one of 12 animals. These 12-year cycles are continuously repeated. The Chinese New Year is celebrated at the second new moon after the winter solstice and falls between January 21 and February 19 on the Gregorian calendar. The year 2006 translates to the Chinese year 4703–4704. The year 2007 translates to the Chinese year 4704–4705."1 "2000 Feb. 5 2001 Jan. 24 2002 Feb. 12 2003 Feb. 1 2004 Jan. 22 2005 Feb. 9 2006 Jan. 29 2007 Feb. 18 2008 Feb. 7 2009 Jan. 26 2010 Feb. 14 2011 Feb. 3 2012 Jan. 23 2013 Feb. 10 2014 Jan. 31" 2 "What about a 'Year?' The next larger unit of measurement of time is the 'Year.' For this we go back to the Sun again. Careful observations reveal that the over a period of many months (12), the position of the Sun shifts from very high overhead to a much lower point at Noon time. The length of daylight time also changes from longer to shorter. Even more importantly, the weather changes from hot to cold, giving rise to the four seasons of Winter, Spring, Summer and Fall. It is logical, therefore, to define the length of this time period as a 'Year.' The Chinese word for 'Year' is 'Nian', written as . Since the word 'Sun' has already assigned the meaning of a 'day', a new word has to be used to denote the 'year.' How long is a year? A little more than 365 days. In 104 B.C. the length of a year was determined to an accuracy of 365.2502 days. By 480 A.D., Ju Chongzhi refined it to 365.2428 days, or 52 seconds more than the modern value of 365.2422 days. To put it another way, in 2,000 years the total discrepancy is less than one day! Together with the voluminous annals of Chinese historians, the Chinese has provided the most accurate and uninterrupted time-line records. Although 0.24 day does not look like much, over many years it becomes significant. How do we round it to a whole number of days? There are several different schemes to do this. The Chinese scheme is called the 'lunar calendar', and the nearly standard calendar is called the 'solar' calendar system. "3

### The dates on which the Sun and the Earth come closer, why these dates haven't a difference of 6 months?

It is true that the Earth's distance from the Sun actually does vary during a year. The Earth's orbit is an ellipse with the Sun sitting at one foci. The closest approach of the Earth to the Sun is called perihelion, about two weeks after the winter solstice. Aphelion occurs when Earth is farthest from the Sun, a couple of weeks after the summer solstice. The difference in distance? About 3 million miles, or about 3% of the total. Here is a schedule I got from somewhere: Year Perihelion Aphelion 2007 Jan 3 20Z July 7 00Z 2008 Jan 3 00Z July 4 08Z 2009 Jan 4 15Z July 4 02Z 2010 Jan 3 00Z July 6 11Z 2011 Jan 3 19Z July 4 15Z 2012 Jan 5 00Z July 5 03Z 2013 Jan 2 05Z July 5 15Z 2014 Jan 4 12Z July 4 00Z 2015 Jan 4 07Z July 6 19Z 2016 Jan 2 23Z July 4 16Z The reason why the dates and times are not exactly 6 months, but rather 6 months plus or minus a day or so is that the year is not exactly 365 days but close to 365.25 days. Which is why we have leap years. This quarter day difference between real time and calendar time is why the dates change as they do.

### when does summer start? or when is the first day of summer?

The Northern Hemisphere welcomes the first day of summer on June 20 or June 21 depending on your location. The astronomical beginning of summer in the Northern Hemisphere is marked by the June solstice. Depending on the year, the day that marks the offical start of summer can be June 20 or June 21. The following is a list of exact dates and times for upcoming summer solstices: June 20, 2008 at 7:59 pm EDT June 21, 2009 at 1:45 am EDT June 21, 2010 at 7:23 am EDT June 21, 2011 at 1:16 pm EDT June 20, 2012 at 7:09 pm EDT June 21, 2013 at 1:04 am EDT June 21, 2014 at 6:51 am EDT The First Day of Summer is Earlier in Western North America For the years 2009 and 2013, people in the Mountain and Pacific time zones and farther west greet the first day of summer a day earlier, on June 20. So when people ask what the first day of summer is, it not only depends on the year but on where you live. The moment of the summer solstice in the Northern Hemisphere is determined by when Earth's North Pole axis is tilted most directly toward the sun. When this is occuring in the Northern Hemisphere, the Earth's South Pole axis is tilted most directly away from the sun, which marks the first day of winter in the Southern Hemisphere.

### when is the longest day of the year and why is it the longest day of the year?

it is called the summer solstice there are 2 solstices tho 1 is the summer and 1 is winter the summer solstice is the day with longest daylight so it is considered the longest day of the year. take a look at this site it will expllain it better then me http://en.wikipedia.org/wiki/Summer_solstice if you dont want to go to the site all just copy and paste and u read it The summer solstice occurs exactly when the Earth's axial tilt is most inclined towards the sun at its maximum of 23° 26' (angle). Though the summer solstice is an instant in time, the term is also colloquially used like Midsummer to refer to the day on which it occurs. Except in the polar regions (where daylight is continuous for many months during the spring and summer), the day on which the summer solstice occurs is the day of the year with the longest period of daylight. Thus the seasonal significance of the Summer solstice is in the reversal of the gradual shortening of nights and lengthening of days. The summer solstice occurs in June in the Northern Hemisphere and in December in the Southern Hemisphere. North of the Tropic of Cancer (23°26'N) and south of the Tropic of Capricorn (23°26'S), the Sun reaches its highest position in the sky on the day of the summer solstice. However, between the Tropic of Cancer and the Tropic of Capricorn, the highest sun position does not occur at the summer solstice, since the sun reaches the zenith here and it does so at different times of the year depending on the latitude of the observer.[1] Depending on the shift of the calendar, the summer solstice occurs some time between December 21 and December 22 each year in the Southern Hemisphere, and between June 20 and June 21 in the Northern Hemisphere.[2] Worldwide, interpretation of the event has varied from culture to culture, but most cultures have held a recognition of sign of the fertility, involving holidays, festivals, gatherings, rituals or other celebrations around that time.[3] It has recently become a popular belief in the United States that the meteorological season of summer begins with the astronomical phenomenon of the summer solstice. However, the period of maximum temperatures in the United States runs from June 4 to September 3.[4][unreliable source?] Other regions reckon the start of summer to the beginning of the month of the solstice, or even the month preceeding it. The word solstice derives from Latin sol (sun) and sistere (to stand still).  Dates and times The following lists the dates and UTC times of the summer solstice for the early portion of the 21st century.[5] Year Northern Hemisphere Southern Hemisphere 2000 June 21, 01:48 December 21, 13:37 2001 June 21, 07:38 December 21, 19:21 2002 June 21, 13:24 December 21, 01:14 2003 June 21, 19:10 December 22, 07:04 2004 June 21, 00:57 December 21, 12:42 2005 June 21, 06:46 December 21, 18:35 2006 June 21, 12:26 December 22, 00:22 2007 June 21, 18:06 December 22, 06:08 2008 June 20, 23:59 December 21, 12:04 2009 June 21, 05:46 December 21, 17:47 2010 June 21, 11:28 December 21, 23:38 2011 June 21, 17:16 December 22, 05:30 2012 June 20, 23:09 December 21, 11:12 2013 June 21, 05:04 December 21, 17:11 2014 June 21, 10:51 December 21, 23:03 2015 June 21, 16:38 December 22, 04:48 2016 June 20, 22:34 December 21, 10:44 2017 June 21, 04:24 December 21, 16:28 2018 June 21, 10:07 December 21, 22:23 2019 June 21, 15:54 December 22, 04:19 2020 June 20, 21:44 December 21, 10:02 to read about the winter solstice go here http://en.wikipedia.org/wiki/Winter_solstice .
