This application is an Android interface to the online Orthodox month, located at http://www.canto.ru/calendar/ (read more about the month on the website). The application is able to show a list of celebrations, liturgical readings and troparia for each day, as well as notify in advance about the onset of a festive event. The data is taken from the site of the month in real time. In case of unstable Internet access, we recommend uploading information in advance for a week, a month or three months in advance (this option is available in the application settings). It is also possible to add certain days to your favorites (for example, a name day or a particularly revered holiday), in which case the application will notify you in advance about this date.
