How to calculate the date 30 days from today
提问by HymanTurky
i need to calculate the date from thirty days using Datein javascript
我需要使用Datein计算三十天的日期javascript
var now = new Date();
Example:
例子：
if today is the 13 February 2013, 30 days later is the 15 March 2013. so something that is different from 30DaysLaterMonth = ActualMonth+1.
如果今天是 2013 年 2 月 13 日，30 天后就是 2013 年 3 月 15 日。 30DaysLaterMonth = ActualMonth+1.
I hope my question is clear.. :) thanks everybody!

In native javascript, use Date.UTC(year, month, day)to get the number of milliseconds from 1971-01-01. Than add days * (86400000) and create date from this value:
在原生 javascript 中，用于Date.UTC(year, month, day)获取从 1971-01-01 开始的毫秒数。比添加天 * (86400000) 并从此值创建日期：
var date_one_ms = Date.UTC(2012, 05, 25);
var ms_in_day = 24*3600*1000; // 86400000;
var date_30_days_later = new Date(date_one_ms + 30 * ms_in_day);
