How can you calculate sunrise or sunset times?

Answer:
The time of sunrise and sunset is very dependent on the precise location and the date in question. Please re-post your question with the date and the city name or ZIP code.

You can calculate the time of sunrise and sunset easily by visiting the United States Naval Observatory web site's Sunrise & Sunset calculator. You will need the date, city and state for US locations, or the date, latitude, longitude and time zone for any other locations in the world.
