A little online application with interactive map that shows sun movement and sunlight phases (with dawn, sunrise, sunset and dusk times) during the given day at the given location.
i want to build a roof which is cut out of a sphere that will block the sun for a certain period of the year. like say between april 15 to aug 15. i am in new delhi
If you superimpose a compass over the detail you would be able to see exactly which direction a garden for example is in so you can ascertain how much sun it is likely to get
show the sun position from summer to winter on the 12 to 6 side of a clock and winter to summer on the 6 to 12 side of the clock. The sun position by day could show from 3 to 9 on the dial. The moon could be added as a circle.
The calc is supposed to show user's local time zone time. Yet I get different results if pressing the 'now' button or choosing - say - a 1900 date (in address bar of browser). Sometimes the sun is south at noon, sometimes at 13:20, which is...
To get an idea how sunrise/sunset move over time (e.g. a month) please have 6 dotted lines or small markers along the outer circle starting & ending with the solstices.
Maybe add a button or hotkey to enable / disable this "grid"
your application is a great tool and I like the UI and that no additional SW is needed (unlike TPE)
Please also look at TPE (Adobe AIR based, http://stephentrainor.com/tools )
Your tools is easier to use, especially if you add a bar to quickly...

Useful to see these; best place probably on the current position line. Also azimuth for sunrise and sunset (when elevation is by definition zero).
Another useful addition would be to clarify what time means; is it local solar time (sun at zenith...
