AstroMath publications

On this website, you can find and download free yearly astronomical calendars and astronomical tables for selected locations for non-commercial use. The calendars and tables are valid for selected locations within Bulgaria, Slovakia or Czech republic only and they are non-transferable. The full VSOP87 and ELP2000 theories were used to calculate the data used for the calendar. Due to frequent updates, this website is available in English only. In case you want to view this website in another language, use Google Chrome to translate it to your desired language. Manuals for the calendars are in English, Bulgarian, Czech and Slovak.

In case you want more calendars and other astronomical graphs for any place in the World, you can generate them using a software. So far, there is only one paid software that can generate calendars similar to mine - AlmSun.
