The Equinoxes and Solstices calculator module
Equinoxes and Solstices

The Equinoxes and Solstices module calculates the date and time of an equinox or solstice for a given year. You specify the year and the date and time of the events (Vernal Equinox, Summer Solstice, Autumnal Equinox, or Winter Solstice) are displayed.

There is a batch mode for this module. To use it, simply generate an input file whose lines each contain a year for which the Equinox and Solstice data will be computed. Then specify the input and output filenames, and press the Compute button to generate the output file. Each line in the output file contains the input year and the date of each event. You can also read the output directly in &kstars; by pressing the View output... button.
