We are at about 8° E, which puts us on the western end of the time zone and thus already shifts daylight nearly 30 minutes later than clock time.</p> <p>However, Orlando - 81°W - is also on the western end of its time zone, which stretches from 67.5° to 82.5°, at least mathematically. So that effect would cancel out, and leave the extra hour of daylight and a longer period of dusk to confuse Linda.</p>tag:sursumcorda.salemsattic.com,2018:/isso/1167/41512015-06-13T19:46:03ZSursumCorda<p>Thanks, Sarah, for reporting on this.</p>tag:sursumcorda.salemsattic.com,2018:/isso/1167/41502015-06-13T13:42:11Zdstb<p>This is one of those questions that I have always meant to investigate. We noticed when we went to Montana several years ago, that it was light out until 10 o'clock at night. I wondered if it was light so late because of our latitude or because we were at the western end of the time zone (or a combination). It seemed our latitude at home or in Maine was not that different, but the time of sunset seemed quite different.</p> <p>So, according to University of Nebraska at Lincoln's Daylight Hours Explorer: http://astro.unl.edu/classaction/animations/coordsmotion/daylighthoursexplorer.html</p> <p>Hours of Daylight on June 13:</p> <p>Emmen, Switz (47 deg N): 15.7</p> <p>Kalispell, MT (48 deg N): 15.8</p> <p>Bath, ME (44 deg N): 15.3</p> <p>Hartford, CT (42 deg N): 15.0</p> <p>Orlando, FL (28 deg N): 13.8</p> <p>At this time of year there are 2 more hours of daylight in Emmen than in FL.</p> <p>This map also shows that time zone has a role. http://gizmodo.com/how-solar-time-compares-to-standard-time-around-the-wor-1535080399</p> <p>Thank you for pushing me to finally look this up. When we did Learner.org's mystery class several years ago, we learned a lot about daylight and seasons. A fantastic game. At least I thought so. The boys were less enthused. https://www.learner.org/jnorth/mclass/</p> <p>The University of Nebraska at Lincoln has a lot of other simulations that I highly recommend. http://astro.unl.edu/interactives/</p> <p>Sarah</p>
