Rahu Kalaya (also known as Rahu Kaal or Rahu Kalam) is a period of approximately 90 minutes each day that is considered inauspicious in Vedic astrology. It is named after Rahu — the shadow planet (lunar node) associated with confusion, obstacles, and unexpected outcomes.
According to Hindu and Buddhist traditions across South Asia, activities started during Rahu Kalaya are believed to face delays, complications, or failure. This includes:
However, Rahu Kalaya is not considered harmful for continuing work already in progress, routine daily activities, or emergency situations. It specifically applies to new beginnings.
In Sri Lanka, Rahu Kalaya is widely observed across Buddhist and Hindu communities. Many newspapers, TV channels, and radio stations announce the daily Rahu Kalaya times. It is one of the most checked astrological factors before planning important events.
The daytime (sunrise to sunset) is divided into 8 equal parts. Each part is approximately 90 minutes long (varies with season). Rahu occupies a specific slot number depending on the weekday:
Since the calculation depends on actual sunrise and sunset times, Rahu Kalaya varies by location and season. Near the equator (like Sri Lanka), the variation is minimal. At higher latitudes (like London or Toronto), the duration changes significantly between summer and winter.
Yama Gandeya (also known as Yamagandam or Yama Kantaka) is the second major inauspicious period in each day. It is named after Yama — the god of death and dharma in Hindu mythology.
While Rahu Kalaya is associated with confusion and obstacles, Yama Gandeya carries a more serious tone — it is traditionally linked to danger, accidents, and harm. Activities started during this period are believed to carry risks of physical harm or severe negative consequences.
Activities to especially avoid during Yama Gandeya:
Yama Gandeya slot assignments per weekday:
In Sri Lankan tradition, Yama Gandeya is taken very seriously, particularly when planning travel. Many people check both Rahu Kalaya and Yama Gandeya before departing on a journey.
Gulika Kala (also known as Gulika Kalam or Mandi Kala) is the third inauspicious period of the day. It is named after Gulika (also called Mandi) — a sub-planet (upagraha) considered the son of Saturn in Vedic astrology.
Gulika is associated with poison, hidden dangers, and negative karma. While less widely known than Rahu Kalaya, it is considered equally important by traditional astrologers, particularly for:
