[Newbie] Date calculations
May 15th, 2006, 5:21pm  
Hello,

I have a very easy calculation to do : how can we know how many days there are between two dates ?

We get these dates from a webpage, in a string parameter "dd/mm/yyyy", and need to use them as coordinates. For the moment I do the calculation in my web page, and send directly the coordinate, but it would be much cleaner to do all these things in the applet.

Do "date" classes exist in Processing for this purpose ?

Thanks for you help.

you should use the java date class, which will let you do all those things:

heh, i did this function just last week


// get number of days between two dates
int getDaysBetween (Date d1, Date d2) {
   int msPerDay = 1000 * 60 * 60* 24;
   long firstTime =d1.getTime();
   long lastTime = d2.getTime();
   int difference = floor(lastTime/msPerDay) -  floor( firstTime/msPerDay);
   return difference;
}
