    If you're only looking for the time of the sun or moon rise then the local paper is the easiest source.

    But if you want to know on what day the sunrise can be seen straight down a particular street, when the sun will set between two hills from a particular vantage point, or whether the sun will come around far enough to shine in the windows on a particular side of a house before sunset, then you need to know about the The Photographer's Ephemeris (TPE).

    TPE is free on your computer. They call it an app, but it works just like many other interactive pages on your browser.

    Much of the relevant ephemeris information in TPE is overlaid on Google Maps. This means that it works for everywhere, except at the poles (yeah, I had to try). And that means you can use either the map or satellite views for working things out. And, of course, you can search for places in the usual Google Maps way.

    If you want The Photographer's Ephemeris on your iPhone or Android phone, however, it will cost you a few bucks. For those you can go to either the App Store or Google Play.

    The home page for The Photographer's Ephemeris is HERE.

    The 0nline Photographer's Ephemeris (browser based) app is HERE

    Their free, quick-start, 2-page guide is HERE.

    And finally, the latest, 80-page, PDF version of Understanding Light with the Photographer's Ephemeris, by Bruce Perry, is available for purchase (£9.99) HERE. Understanding Light talks about more than just the use of the ephemeris. I found it very useful.

    (I have no association with TPE and the links above are just their links. I get no benefit.)

    It is a great app, however I much preferred it when it was a program on a computer. The app requires that I have internet access to use it and that is not always possible for me.

    Feel exactly the same......much nicer when it was a program without the need of internet access. This application is useless now when I am out in the middle of nowhere.
