Using this program you can determine the dates of the occurrence of New Moons and Solar and Lunar Eclipses.
In the Solar eclipses section you can also see a map with the Solar Eclipse Central Line over the world and you will be able - by choosing a city - to see if the eclipse is visible in there or not.
The program also includes a help file with pictures and movies, but due to his size it is not included in the basic installation.
New to version 1.2: AstroMAT now supports "Windows XP" themes and shows the menus like the ones you may be familiarized with in the "MS Office XP" suite.
The link in the name (above) points to the English installation file. There's also a Portuguese version of the program you can get here.
