Sun calculator

If you google the above header, you'll get a lot of online programs which calculate all kind of ephemerides. Here is a new one with the features that may be useful for sundialists:

  • with Geolocation API you can easily get your current location and watch Sun's ephemeris in real time (and slide show, if your screen is wide enough);
  • for a given time/location you can get a CSV-report with daily and/or annual ephemerides;
  • with Sun calculator you can know the dates for Pesah, catholic Easter and orthodox Easter;
  • for a given latitude you can get a PDF-file with a pattern of horizontal sundials.

Easy to use, adaptive modern design, no registration, no cookies, no Java, no irritant adds.
