If you'd like these times for a different location go to the Complete Sun and Moon Data for One Day, or Sun or Moon Rise/Set Table for One Year from the United States Naval Observatory (USNO). It calculates sunrise, sunset, moonrise, moonset, twilight and the Moon's phases for locations in the US and other locations world wide.

More information for this or any year

Here’s a link to the USNOs Astronomical Applications Department.

NASA’s Eclipse web site has information on solar and lunar eclipses past and future plus information on transits of Venus (don’t hold your breath*) and Mercury (November 11th this year).

NASA’s Sky Events Calendar: Display and print in calendar page or tabular format sky events, like the Moon’s phases, solstices and equinoxes, meteor showers, and planetary conjunctions for any month or year.

* My great grandson, born this year, will be able to see the next one if he lives to be 99 years old and moves to Australia. If you didn’t see the transits of Venus in 2004 and 2012, you won’t ever see one.
