Daylight Savings Time!

The only way I can ever remember which direction Daylight Savings Time changes the time is with the saying "spring forward, fall back." The fact that the direction of the changes is dictated by the season (i.e. how early the sun rises and sets) should have made it obvious what would happen with the time in the southern hemisphere relative to the northern hemisphere. In fact, I never stopped to think about this until... yesterday.

When I arrived in Brazil on October 6, I was one hour ahead of the US's east coast. One day, I woke up,  my cell phone time had sprung forward, and I was magically two hours ahead of the east coast. On Sunday, the east coast fell back, and I am now three hours ahead.

This is not earth-shattering news. It's just kind of weird. I'm guessing that this has never occurred to most people who have not switched hemispheres or do not work with people in the opposite hemisphere.

So, now you know.
