Some Celestial Events for 2013

Question:  Regardless of Time and Time Zones, what location (coordinates) on Earth will be first in January 2013 to experience the following:

  1. In the evening the Sun sets in the west before the “visibly” Full Moon rises in the east–Might be Jan. 27th, 2013 Waning Gibbous 99%
  2. The next morning the Sun rises in the east before the Moon sets in the West.–Might be Jan. 28th, 2013 Waning Gibbous 97%

What locale will be first in February?

Is there a computation, algorithm or software that could help predict where and when this would occur every month?

Is there a way to timestamp localities on earth without using time zones–a way of keeping local time using celestial signs in a way that one could compare differences from one local to another?  – David

Answer: For your Sun and Moon position questions, let me refer you to a listing of such astronomical events.  This list contains Moon phase, Sun location, and other astronomical events for 2013.  As for your question asking for what “locale” will be first in February, I am not sure what you are referring to.  There are algorithm’s that can be used to predict the astronomical events described in the link I provided.  See the information at the end of that link for details.  Finally, yes there is a way to timestamp a given location, without using time zones, by measuring the relative positions of stars at those two locations.  This is called “sidereal time”.  I hope that this answers your questions.
