A while back, I posted a fairly long discussion of the astronomical solstice. Here's a piece of it:
For those that are curious, the remainder of the thread discussing the astronomical phenomena is at: Link to FAQ: What is the astronomical meaning of Solstice?Crimson Avenger said:The times for the Solstices and Equinoxes are shown at: link to Us Naval Observatory: Earth's Seasons...1992/2020. Now, when your reading the chart, note that the times are displayed in Coordinated Universal Time pretty much the same as [GMT] or the times in Greenwich England. So for the Eastern US Time Zone, subtract 4 hours (when Daylight Saving Time is in effect [Summer Solstice and Autumnal Equinox] and subtract 5 hours when Eastern Standard Time is in effect [Winter Solstice and Vernal Equinox]. For those out in the west, the Daylight Saving Time offset is subtracting 7 hours and for Standard Time, it's subtracting 8 hours.
For example, the Summer Solstice for 2005 occurs 2005-06-21 06:46:00Z or
So, the sunrise on 2005-06-21 is the Summer Solstice sunrise this year.
