24 solar terms is good tools for Chinese farmer. And now summer is coming. Let’s look at how to calculate of Grain Buds Date.
Formula: [Y*D+C]-L
Note: Y refers to the last two numbers of a year, such as 10 in 2010, 08 in 2008 D=0.2422 L=the number of leap years 21st century C=21.04 20th century C=21.86
公式解读：Y=年数后2位，D=0.2422，L=闰年数，21世纪C=21.04，20世纪=21.86。
Example: The date of Grain Buds in 2088=[88×0.2422+21.04]-[88/4]=42-22=20, Grain Buds falls on April 20th.
举例说明：2088年小满日期=[88×.0.2422+21.04]-[88/4]=42-22=20，5月20-21日小满。
Exceptions: 2008, add one to the calculated result.
例外：2008年的计算结果加1日。
