Ephemerides is a computer program which computes times of minima of eclipsing binary stars. The data of variable stars are read from several catalogue files. It is intended to be used off-line, no internet connection is required at run-time. The current version works in the MS Windows 98 SE, 2000, XP, Vista and Windows 7. It is intended for visual, CCD and PE observers.
The graphical user interface is very simple and intuitive. It can be run in the two operation modes: the computation ephemerides for one specific night or the computation of ephemerides for a particular variable star and a season. It is possible to print the table of minima on a connected printer or save it to an ASCII, HTML or CSV file.
It is possible to build and use a custom catalogue file of your own variables.
