About this web site
Gaisma website provides sunrise, sunset, dusk and dawn times for thousands of locations all over the world. Sun data is shown in table format for selected dates and as a graph for the whole year. Possible daylight saving times are taken in the account.

Sunrise and sunset calculations are based on the algorithms shown on National Oceanic and Atmospheric Administration Earth System Research Laboratory web site. For latitudes less than 72° north and south, accuracy is approximately one minute. For latitudes greater than 72° north or less than 72° south calculations are accurate to within 10 minutes.
