In two weeks, I’ll be traveling again to New Zealand for work. Though the contrast will not be nearly as stark — last time, it was snowing in Seattle when I left and I hit the beach on a bright summer day in Auckland the day I arrived — I’ll be in the Southern Hemisphere for the Spring Equinox on September 22. That means that in just 17 days, I’ll spend time in all four seasons.

I made an infographic illustrating this quirk of global travel caused by the tilt of the Earth’s axis.

EDIT: Antipodean friends inform me that Spring begins on September 1st in both New Zealand and Australia. Frankly, I find that ridiculous. Spring begins at the equinox, and isn’t something you shuffle around at the national level as though it were Daylight Savings Time. I’m sticking to my guns on this one!
