java script date issue

giridhar

Hi, ihave a doubt a please clarify me.

i want to go back to four weeks back dates from todays date in my javascript code,

i can directly go back by subtracting 28 days,but every month can have 30 or 31 or 28 or 29 days.

so, I can't get correct exact date by directly subtract days from the date.

how can i go back to the particular date. And i want to know how many days are in the last month.

is there any functions to acheive this in javascript.

please give your suggestion.

You could use something like this to get the days in a given month<br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>function DaysInMonth(y,m) {
return new Date(y,m,0).getDate();
}</pre>
