So I thought I'd look up the actual sunrise and sunset times, and see if they're really all that different from when we lived in Philadelphia, or better yet, when we lived in Michigan -- because I know they were definitely different in Michigan compared to Philadelphia. We were much further north in the time zone, and almost as far west as you could be and still be in the same time zone. I'd have to see where we are comparatively, east-to-west, in the time zone here, but I do know we're much further north than we were in Ann Arbor (47th parallel here in Seattle; 44th parallel in Ann Arbor; 40th parallel in Philadelphia).
very cool tools, including ones where you can get the sunrise and sunset data for a single day, or a whole year.
So I looked up May 29, 2009, for all three locations, and here's what I got:
- Seattle: Sunrise, 5:17 am; Sunset, 8:57 pm
- Ann Arbor: Sunrise, 6:02 am; Sunset, 8:32 pm (wow, they really are different...)
- Philadelphia: Sunrise, 6:35 am; Sunset, 8:22 pm.
Now I'm curious... how about Summer Solstice?
According to the US Naval Observatory, Summer Solstice 2009 is on June 21st, at 5:45 am UT (Universal Time). In Seattle, we're in the Pacific Time Zone, UT-8, so Summer Solstice for us is at 9:45 pm the night before, June 20th. Ann Arbor and Philadelphia are in the Eastern Time Zone, UT-5, so Summer Solstice is at 12:45 am on June 21st.
- Seattle, June 20th: Sunrise, 5:11 am; Sunset, 9:11 pm
- Ann Arbor, June 21st: Sunrise, 5:59 am; Sunset, 9:15 pm
- Philadelphia, June 21st: Sunrise, 5:32 am; Sunset, 8:33 pm.
So on Summer Solstice, we have
- 16 hours of daylight in Seattle;
- 15 hours, 16 minutes of daylight in Ann Arbor; and
- 15 hours, 1 minute of daylight in Philadelphia.
Today's post is brought to you by the joys of scientific geekdom in the service of spiritual mysticism. :)
