Sidereal Time vs. Tropical Time

Sidereal Time is a timekeeping system that is based on the Earth’s rotation relative to the stars. It measures the time it takes for the Earth to complete one rotation on its axis. Generally, Indian astrology, also known as Vedic System, uses the sidereal zodiac. This system aligns with the actual positions of the stars and is considered more astronomically accurate

Tropical Time, on the other hand, is based on the Earth’s rotation relative to the Sun. It defines a year as the time it takes for the Earth to complete one orbit around the Sun, which is about 365.24 days.  In contrast, most Western astrologers use the tropical zodiac. This system is more focused on the seasons and the relationship between the Earth and the Sun.
