In Vedic timekeeping and electional astrology (Muhurat), Choghadiya is a time-tested mathematical framework used to identify favorable and unfavorable time windows across any day or night. The term stems from Chau (meaning four) and Ghati (the ancient Vedic unit of time equal to 24 minutes). Historically, a single Choghadiya slot spanned 4 Ghatis, totaling exactly 96 minutes.
In practice, daytime (from local sunrise to local sunset) is divided into eight equal segments, and nighttime (from local sunset to the next sunrise) is divided into eight equal segments. Because day length fluctuates throughout the seasons, calculating dynamic sunrise and sunset times based on your precise latitude and longitude is essential for reliable results.
