Shadow Calc helps you to calculate hours of unobstructed daylight and shadow for any date of the year and any place on earth. There are many reasons why you might want to know that:

- Maybe you want to buy or rent a new flat: How do you know there will be unobstructed sun on the balcony in winter?
- You might have plans for a flower bed. Will there be the required minimum hours of sun throughout the year?
- You plan to shoot a picture of the sun coming right over the hill. Whats the time to get up?
- You shun the sun when it reaches its zenith. What time should you go inside?

You simply provide the coordinates of your location of interest and of a possible obstruction; then Shadow Calc has the answer to those questions.
