There's now a new page which includes a google maps tool for showing where and when the moon will rise and set, along with the astronomical twilight times, ephemeris dates and current moon for your particular location.
Moon & Night Photography Calculator
Feedback. Is there anything else you'd like to see included in this tool? Is there anything about the user interface that could be made easier? Also, the times given by this calculator should be as accurate (or more so) than anything else out there. If you notice any odd discrepancies, please let me know.
Instructions. You may see a message in your browser asking permission to share your location; if you accept, then your present location will be automatically estimated on the map. Otherwise it will default to GMT and you can move the location marker or search for your location in the box above the map. Your date and local time are also automatically entered.
FYI, this is mainly intended as a learning tool, and as a companion to the earlier common obstacles in night photography and making the most of natural light in photography tutorials. As others have pointed out, there are also several useful mobile phone apps out there which estimate these times, so for in-the-field use, those are worth looking into as well. Maybe someday I'll lump all of the site tools into an all-in-one photographer's toolkit app for Android and iPhone...
