How can you calculate the difference in two dates that are in different formats?
I have one date as: '2010-06-16 21:20:44.000'
and the other date as now = new Date();
I want to subtract the dates to see if it is over 30 days.
For my website i would like to display the age of my son in years,
months, days and hours.
For now i manage to get a result for totals. Like the total number of
days.
This is the beginning:
starttime = Date.parse("Aug 10,2003, 07:07")
sdt = new Date(starttime)
starttime= Math.ceil((starttime) / 1000 / 60 / 60 / 24 )
ndt = new Date()
y = sdt.getYear()
m = sdt.getMonth() + 1
d = sdt.getDate()
h = starttime
Calculating the difference between two dates in JavaScript is relatively straightforward, provided you choose the right Date methods to work with. Whichever way you get there. code...

My problem is the 1st date is using a different format this is the example:2010-05-01 13:46:04 the second one is I am trying to get the today's time and date by using this code: "currentTime.getTime()". Here is my whole code

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.
I have two date fields (check in, check out) and "number of days"
field.
I want the script to calculate automatically the difference.
For example: I have defaults dates, and I want the script to put the
difference in "number of days" field. And if the user will change the
date, the number of days will change automatically.
How do I get the difference in days between 2 dates using Javascript?

& then I have put

This gives a value of 2,678,400,000 but the amount of milliseconds in a day is actually 86,400,000
i've written a js function to find the difference between two dates. the format being used is dd/mm/yyyy hh:mm. The function returns correct value when give one set of values, but go wrong with another set. examples are given below.
set 1 : Time 1 = 24/02/2011 09:30 , time 2 = 24/02/2011 16:00
Output is corret here. It gives 6 Hours & 30 Minutes (after converting the difference)
set 2: Time 1 = 24/02/2011 09:30 , time 2 = 25/02/2011 16:00
Here, it gives 31 days, 6 Hours & 30 Minutes. My code is given below. Also the alert of dates display strange values. Don't know if it is timezone issue.
function compareDateTime(frmtime,totime)
{
var date1 = new Date(frmtime);
var date2 = new Date(totime);[code]......
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

I am new to Java scripts. But at my job, my boss asks me to come up with a calculator that calculates the number of weeks on our website. But I want two calenders where in the first one the user will select the start date and in the second one, the user will select the end date. And There will be one last button that says"calculate" and a text box to display the number of weeks.
View 14 Replies View RelatedI am trying to change the date formats in an invoice.
Currently it is should as this: 2011-11-01 11:57 AM
I should show that in the following format: Nov 01, 2011 11:57 AM
Below is the function I wrote to do this.
But here is the problem. When the hour is a single digit, it takes the space obviously and the result is "undefined".
e.g.
2011-09-15 9:46 AM is showing as Sep 15, 2011 undefined:6 AM
So, splitting the text based on the position is not working fine. Is there is an effective way of doing this?

where I can get a Date and Time Picker that will only allow to choose current dates instead of past dates written in Javascript or JQuery?
View 5 Replies View RelatedI've inherited a Form which calculates a future date based on a calculation and then inserts today's date and the future date into a database. The day part of the date is formatted as a number. This is fine, but up to 9 the numbers display in single figures with no leading zeros. I want them to display leading zeros (e.g. 01, 02, 03, 04, 05, 06, 07, 08, 09, 10, 11... 30, 31) So;
1/12/2010 is NOT wanted
01/12/2010 IS wanted
The inherited code originally set the Month names as "Jan", "Feb" etc, and it was easy to kludge these to 01, 02... 12, but I suspect there's a more elgant solution to this as well, this bit of the code works so it's not as vital to neaten this but my database needs dd/mm/yyyy format (it's a third party email program).

I inherited an html demo (used to show customers our product w/o being connected to a server). Was going through the Html files to update the dates and fields and it seems that on some html files, when I change a date <td>08/11/2008 </td> to <td>08/11/2011</td>, save and refesh, I start getting a bunch of JS errors when I try and log back into the demo. I'm not changing anything in the JS files, so I don't understand why the errors are occuring.
I have a bunch of html files to change, and now, no matter which file I change (the dates, sample names, etc), I lose functionality on that particular page.
What is the difference between DOM, Javascript and DHTML?
Alert() and document.write() is a DOM method or Javascript method?
document.write("<td><a href=clips/"+genericname+".mpg document."+genericname+".dynsrc='clips/"+genericname+"mpg' src=logos/"+genericname+".jpg name="+genericname+" border=0></a></td>");
This line is meant to be used in conjunction with a loop routine in <script> brackets within the main <body>. What it should do is display a file pictures and then play its mpg file on a mouseover, for a generic filename that can be changed. That i can do. The problem is within the line ...
document."+genericname+".dynsrc='clips/"+genericname+"mpg'
Here i want to play the mpg and keep its height at 75. The problem is that it doesn't work. I think that the two document strings should be surrounded by "...
document."+genericname+".height=྇' document."+genericname+".dynsrc='clips/"+genericname+"mpg' "
However because i'm using the "+genericname+" command within the line, i can't use " to surround the two document strings. I've tried to do it as a function, but i can't get it to work as a generic function.
