Philips Savvy Biocalendar

My first phone back in 1999 was a Philips Savvy. This phone had an application called "Biocalendar" which would tell you your Biorhythms. This is apparently a way of rating your chance, love, energy and success on a particular date, based on how old you are on that date.

While not particularly useful, it provided mild entertainment in the pub, so here it is brought back to life through the medium of Javascript!
