Sunrise, sunset

No, not the song from Fiddler on the Roof…

Have you ever wanted to know the sunrise, sunset, moonrise, moonset and twilight times for a given day?  Try You can plug in one of the major cities on the main page, or drill down to your exact location by either using one of the U.S. cities, or by entering your latitude and longitude.  Once the calculator has your location, you can generate a calendar for a given month.  I print mine out and stick it in my astronomy binder.

You can select what you want to see: just sunrise and sunset, or also moonrise and moonset, and the various different ‘twilights’ (which are useful when planning observing sessions).  There’s also a nifty system tray tool that you can download.
