The year is three quarters finished or at least it is for me. I am a teacher. A seventh grade language arts teacher and the third quarter finished Friday. We have one week before Spring Break begins and then the long march through April and May to finish the year. This year, we’ll be marching, probably more like stumbling, into the first full week of June.
Spring arrived this week on Thursday at 11:57 AM CDT local time. My students have been measuring sunrise, sunset, and the amount of daylight for locations across the globe – ranging from Tromso, Norway at 70°N to Stanley, Falkland Islands at 52°S and places in between. We began measuring last September on the occasion of the autumnal equinox and have been checking every month on the 22nd ever since. The students have gathered a lot of data. However, the lesson they learned was that Earth’s tilt is changing constantly and Thursday they realized that no matter where a person was on Earth Thursday the sun shone a tad bit more than twelve hours – the variance among the 32 locations we checked was ten minutes: from 12 hours and 16 minutes at the northern and southern extremes to 12 hours and 6 minutes nearest the equator.
