Calendar Biorhythm Astrology profiles DatePlus is a software that calculates the day of the week of any date considered since the reform of the Gregorian Calendar (October 15th, 1582). It offers in addition the option to consult the Saints'Days, to make searches of saints by name, to visualize and print the calendar of the month and year, and to configure the presentation of the weeks (Sunday - Saturday, or Monday - Sunday). In addition we can accede to the number of day and week (referred to January 1st of the studied year), and to the Julian day. In this new version we can find out the number of existing days between two dates and add or reduce an amount defined of days taking to a date like reference. Also we will be able to consult the Biorhythm of a person and its profile of behavior according to the interpretation that makes the Chinese Astrology, Celta, Mayan, Aztec, Hindu and the traditionally well-known one like western astrology.
