MB Midheaven Astrology calculates your midheaven sign based on Western Astrology concepts. The Midheaven represents the life's goal of a person, his standing in society and reputation. Along with the sun sign and moon sign, the Midheaven sign also helps you understand yourself better. This has given rise to a most unconventional kind of astrology. This is a part of angular astrology or the different angles made on your birth chart.
