The easiest way is to use JavaScript's native Date object. That object has a method called 'getTime()' that returns the number of milliseconds since the Unix epoch (Midnight, 1 January 1970, UTC)
To determine how long between two separate events, you'd simply set a pair of variables at the start and the end, and then do the math. This will return the number of milliseconds between the setting of the two variables.
var dateA = new Date().parse('March 21, 2012');
/*thing you want timed goes in here*/
var dateB = new Date().parse('July 15, 2012');
var difference = dateA - dateB;
//difference will now contain 10022400000
You will certainly want to turn that into a more readable format. See the related JSFiddle for complete code on how to work with this object.

To calculate the four number game in javaScript ..... I assume you are asking how to calculate the total of the 4 numbers? A simple function calculating the array (assuming you are using an array) is the easiest way. function calculate(array) { var total = 0; for (var counter = 0; counter < array.length; counter = counter + 1) { total = total + array[counter]; } return total; }
Average speed.
Total distance and total time.
Total Distance: Distance from some fixed point at end - Distance from the same fixed point at start. Total Time: Time at end - Time at start. Not sure what is meant by "calculate them altogether".
i donnt knoww .?
Speed = Distance/Time
The distance travelled, and the time taken.
you calculate average speed by dividing the total distance to the total time.
normal working time divided by total working time.
Total distance traveled & total elapsed time.
the average speed is the total distance traveled divided by the total time.
You can calculate the total revenue percentage by substituting the variable X for the monthly revenue, the variable Y for the period of time, and then multiple these to solve for the total revenue percentage.
