Comparing two dates with javascript or datejs (date difference)

Question

I am trying to compare two dates which are in Finnish time form like this: dd.mm.YYYY or d.m.YYYY or dd.m.YYYY or d.mm.YYYY.

I am having a hard time finding out how to d

Answer 1

If you are using Datejs, and the optional time.js module, you can run your calculations with the following code by creating a TimeSpan object:

Example

// dd.mm.YYYY or d.m.YYYY
// dd.m.YYYY or d.mm.YYYY

var start = Date.parse("20.09.2011"); 
var end = Date.parse("28.09.2011");

var span = new TimeSpan(end - start);

span.days; // 8

Of course the above could be simplified down to one line if you really want to be extra terse.

Example

new TimeSpan(Date.parse(end) - Date.parse(start)).days; // pass 'end' and 'start' as strings

Hope this helps.
