We think that all of the mystery locations will have about 12 hours of daylight on March 20, 2006. We're not as sure about Mystery location #6. Some rapid changes will have to take place if they only have 12 hours of daylight by then. On our line graph, if we extend the lines, they look like they will intersect at 12 hours on March 20 * except for #6. Equinox means equal day and night for everyone * that should be true for all places on earth.
