How do you get the seconds alive integer to be displayed with the appropriate commas?

Awesome! Thanks, that worked!

Sorry, how do you use that with document.write?

Hey Russel, this is what I did:

var secondsPerMin = 60;

var minsPerHour = 60;

var hoursPerDay = 24;

var daysPerWeek = 7;

var weeksPerYear= 52;

var secondsPerDay = secondsPerMin * minsPerHour * hoursPerDay;

document.write("<h3>There are " + secondsPerDay.toLocaleString() + " seconds in a day.</h3>");

var yearsAlive= 34;

var secondsAlive = secondsPerDay * daysPerWeek * weeksPerYear * yearsAlive;

document.write("<br><h2>You have been alive for more than " + secondsAlive.toLocaleString() + " seconds.</h2>");

Can I see how you used that with document.write? I don't understand.

Russell, I'm pretty new to this myself but I did a bit of research because I was curious as well. It seems you first have to define a new variable that calculates the total seconds in a day. You can't just use the mathematics along with the .toLocaleString() command (I may be incorrect here).

So you could add:

var secondsPerDay = secondsPerMin * minPerHour * HourPerDay;

Your message var:

var message = 'There are ' + secondsPerDay.toLocaleString() + ' seconds in a day';

Then finally:

document.write(message);

Christopher, thanks a lot! Nice and simple.
