now issue here is, counter starts counting down 30 days when page gets loaded. there way first string (since that's issue here think) act custom date setting can choose when starts counting, or better if possible counts point?

the page close bound code, wrong value stops page loading @ , counter handles various events on page, which, keep.

the countdown.js jquery engine made hilios. page of code at: https://github.com/hilios/jquery.countdown

thanks get,

change following line:

var targetdate = new date().gettime() + 2592000000

to this:

var targetdate = new date(2016, 7, 1, 5, 30, 0) // change values correspond date want

this set target date monday august 1st, @ 5:30.

look @ https://developer.mozilla.org/en-us/docs/web/javascript/reference/global_objects/date more info on creating dates.
