Calculating Sunrise and Sunset 2

[HenrikOlsson]

Henrik,

Right, no need for runtime data.

Any idea where a kind of data table would be to be found?

Let me Google that for you....

It defaulted to Gothenburg for me so obviously you'll need to change that.

Isn't the changing sunrise and sunset times mostly a sine wave function, with the 2 times opposite of each other. Basic has a sin function. and the sin values would synchronize with the date and the sin multiplier for minutes change/day value would depend on the latitude of the location of the clock....
