What is Rahu Kalam?
Rahu Kalam (also written as Rahu Kaal or Raahu Kaalam) is a specific period of approximately 90 minutes each day that is considered inauspicious in Hindu astrology. This time period is ruled by the shadow planet Rahu, one of the nine celestial bodies (Navagraha) in Vedic astrology.
During Rahu Kalam, starting new ventures, important tasks, or auspicious activities is traditionally avoided, as Rahu is believed to bring obstacles, confusion, and unfavorable outcomes.
Daily Rahu Kalam Timings
The Rahu Kalam period follows a fixed sequence based on the day of the week. For a standard sunrise at 6:00 AM and sunset at 6:00 PM (12-hour day), the approximate timings are:
| Day | Rahu Kalam | Easy Formula |
|---|---|---|
| Sunday | 4:30 PM - 6:00 PM | 8th period |
| Monday | 7:30 AM - 9:00 AM | 2nd period |
| Tuesday | 3:00 PM - 4:30 PM | 7th period |
| Wednesday | 12:00 PM - 1:30 PM | 5th period |
| Thursday | 1:30 PM - 3:00 PM | 6th period |
| Friday | 10:30 AM - 12:00 PM | 4th period |
| Saturday | 9:00 AM - 10:30 AM | 3rd period |
Memory Formula: The sequence is 7-1-6-4-5-3-2 (Sunday through Saturday), representing which 1.5-hour slot of the day is Rahu Kalam. A popular mnemonic is: "Mother Saw Father Wearing The Turban Suddenly" (Monday, Saturday, Friday, Wednesday, Thursday, Tuesday, Sunday).

Yamagandam and Kuligai
Along with Rahu Kalam, two other inauspicious periods are observed:
Yamagandam (Yama Kalam)
Ruled by Yama (the god of death), this 90-minute period is considered even more inauspicious than Rahu Kalam for certain activities, especially travel. The sequence follows: 5-4-3-2-1-7-6 (Sunday through Saturday).
Kuligai (Gulika Kalam)
This period is ruled by Gulika (son of Saturn) and is avoided for starting auspicious activities. Births during Gulika Kalam are given special attention in chart analysis.
Rahu Kalam Remedies
If you must perform an important activity during Rahu Kalam, these remedies can help:
- Chant Rahu Mantra: "Om Raam Rahave Namaha" 108 times
- Worship Lord Hanuman: Hanuman is the most powerful protector against Rahu's negative effects
- Light a sesame oil lamp: Offering to Rahu with black sesame seeds
- Donate: Give dark-colored items (black cloth, black sesame) to the needy
- Wear Hessonite (Gomed): After consulting an astrologer
Scientific Perspective
While Rahu Kalam is deeply embedded in Hindu tradition, it's important to understand that it is based on astronomical calculations of planetary positions. The timings are mathematically precise, dividing daylight hours into eight equal parts.
Many people observe Rahu Kalam as a cultural practice, using it as a mindful pause before making important decisions — which itself can be beneficial regardless of astrological beliefs.
Conclusion
Whether you follow Rahu Kalam strictly or simply use it as a cultural reference, understanding this concept helps you connect with the rich tradition of Hindu timekeeping. Check our daily Panchangam for accurate Rahu Kalam timings specific to your location.
