Enter your and your friends' birthdays using the form below. The information will only be stored on this computer, not on the server, so don't worry! (PS - I also have some printable space birthday worksheets you can download if you want to do these calculations yourself.)

  • Your/your friend's name:

You need to enter the year correctly - your Jupiter birthday doesn't fall on the same day each year, in fact most years you don't even have one!
