Date对象是JavaScript语言中内置的一种数据类型。日期对象被创建为新的Date（） 。
创建Date对象后，可以使用多种方法对其进行操作。大多数方法仅允许您使用本地时间或UTC（通用或GMT）时间来获取和设置对象的年，月，日，时，分，秒和毫秒字段。
ECMAScript标准要求Date对象必须能够在1970年1月1日之前或之后的1亿天内以毫秒为单位表示任何日期和时间。范围是正负273,785年，因此JavaScript可以表示直到275755年的日期和时间。
与其他JavaScript对象类似，我们也可以在CoffeeScript代码中使用date对象。
以下是JavaScript的Date对象的方法列表。单击这些方法的名称，以获取示例说明在CoffeeScript中的用法。
