## Difference Between Two Dates?

Jun 1, 2009

I would like to know how to achieve this. I want to know the difference between two dates in months, how much days left over, and how much hours left over. I do not need days or hours equivalent to the months remaining. The problem is I also want it to consider February's less than 30 days and 29 days in leap year. I spend my entire week trying to figure out how to do it.

In the end I want values in variable months_left, days_left, and hours_left. I tried modifying several date deference scripts but I couldn't get them to work as intended.

Jul 23, 2004

Code:
<script language = 'JavaScript'>
<!--
function checkDate()
{ var d1, d2
d1 = new Date(document.form1.date1.value)
d2 = new Date(document.form1.date2.value)

if (d2.getTime() < d1.getTime()) {
window.alert ("The end date can not be before the start date.")
return false } else { return true }
}
//-->
</script>
, where date2 is the end date and date1 is the start date.

& then I have put
PHP Code:

## JQuery :: Calendar To Get Difference Between Two Dates And Split Up Variables

Oct 5, 2011

I'm working on redesign of a vacation rental company web site, and I'm looking to use a drop down calendar to select the arrival/departure date on the search form. getting the number of nights difference between dates (though I think the code/labels are slightly backward in that example), but I don't know where to start to split off the variables I need. Basically, the search.php file I'm passing the variables to need to be in this format:

Code:
search.php?month=(arrival month digit)&day=(arrival day digit)&year=(arrival year, 4 digits)&days_count=(number of nights)(...plus some other variables...)

how to split things off properly and get a properly formatted URL? I'll experiment a bit, and come back here with sample code

## JavaScript Date Difference, Accounting For Leap Years

Jun 19, 2006

I'm really sorry to post this as I know it must have been asked
countless times before, but I can't find an answer anywhere.

Does anyone have a snippet of JavaScript code I could borrow which
calculated the difference in years and days between two dates, and
takes leap years into account?

I'm calculating the difference in the usual way, i.e....

var difference = dateTo.getTime() - dateFrom.getTime();

....and converting this millisecond value into days by using...

var daysDifference = (difference/1000/60/60/24);

But how do I then display the difference in days AND years? I've tried
the following:

var yearsDifference = Math.floor(daysDifference/365.25);
var daysLeft = Math.floor(daysDifference-(yearsDifference*365.25));

....but it gives me inaccuracies. For example, if I use my code to
calculate the difference between 05/01/1998 and 05/01/2000 it returns 1
year and 364 days!

## Javascript To Display Current Date (and Back Dates)

Jul 23, 2005

I've browsed through past usenet archives, but can't seem to come across quite the javascript I'm looking for. I'm looking for a simple javascript that will display the date as such:

May 17

So basically, just displaying the current month and the current date. But I would also like the ability to backdate by one day, two days, etc.. So the next date might look as such:

May 15

Which would be two days earlier than today's date, but in keeping with the same format.

## JQuery :: Eyecon Date Picker Plugin - Doesnt Show Dates?

Sep 23, 2009

Still a bit of a jquery newbie here, I'm making a form and using the date picker plugin by eyecon. But when the calendar pops out, instead of seeing the month and dates, It just repeatedly prints 'NaN'. This is super freaky and I cant figure out why.

Here is a link to the page [URL]... Just scroll down to start day and end day under trip information and click on the input box and you'll see what I mean.

I hope someone out there is familiar with this plugin because it was super easy to implement and the code is really clean. [URL].. Here is my js invocation code looks like \$('.startDay').DatePicker({
