Help & how to use this page

Important comment: The data in this page (unless otherwise noted) is calculated for midnight of date. If for example, you are interested in data for the night of 2008 August 17/18, insert the date "18 08 2008". Note however, that in this example, the Moon/Sun rise/set will be calculated for the day of 2008 August 18!
Accuracy: The sky maps are plotted for the nearest whole
local sidereal hour.
The rise/set times are accurate to about two minutes and are given relative to the local horizon. Note, that the actual rise/set times depends on the atmospheric conditions.
