Rahu mahadasha is the period of ambition and the unfamiliar: foreign lands, new technology, sudden rises and unconventional paths. Rahu owns no sign, so the texts read it through its sign lord (dispositor), the house it occupies and the planets it joins: well supported, they credit it with lifting a person far beyond their origins; poorly supported, they link it to confusion, deception, anxiety and unusual health complaints.
Each antardasha lasts mahadasha years × its lord's years ÷ 120, in the order of the cycle starting with Rahu itself. Lengths are shown as the traditional tables print them (12 months of 30 days); the dasha calculator dates every one exactly for a birth.

| Rahu – Saturn | 2y 10m 6d | 2.85 | 7y 11m 12d |

Rahu rules no sign, so its mahadasha brings the matters of the house it occupies and the results of its sign lord. Read the house it sits in for your chart:
- Rahu in the 1st houseRahu on the lagna amplifies the self: ambition, an unusual or foreign-tinged personality, the urge to stand out and a restless sense of identity.
- Rahu in the 2nd houseRahu in the 2nd makes the voice persuasive but unpredictable: the texts warn of untruthful or harsh speech, family discord and wealth gained or lost through unconventional or foreign sources, with complaints of the mouth or teeth.
- Rahu in the 3rd houseRahu in the 3rd is the self-made achiever: by the classical texts a malefic node in this upachaya house gives courage, enterprise, success over rivals, wealth and long life, with bold, persuasive communication.
- Rahu in the 4th houseIn the 4th house of home, mother and peace of mind Rahu unsettles: the texts read restlessness, frequent moves or a life abroad, complications in property and vehicles and an anxious relationship with the mother or homeland.
- Rahu in the 5th houseIn the house of children, intellect and romance Rahu brings unconventional brilliance and an appetite for risk: the classical texts warn of delays or worries around children, speculative losses and confusion in romance.
- Rahu in the 6th houseRahu in the 6th devours its opponents: the classical texts count the 6th as its strongest house, where it defeats enemies, overcomes debt and disease and gains wealth through competition.
- Rahu in the 7th houseIn the house of marriage Rahu brings the unconventional into partnership: the classical texts read attraction to someone from a different background, culture or country, delays or misunderstandings in marriage, and partners who are ambitious or hard to read.
- Rahu in the 8th houseIn the 8th house of sudden change and hidden matters Rahu is intense: the texts warn of sudden reversals, hard-to-diagnose complaints, disputes over inheritance or joint money, and secrets.
- Rahu in the 9th houseIn the house of dharma, fortune and the father Rahu challenges inherited belief: the texts read an unorthodox or changing faith, friction or distance with the father or teachers, and fortune through foreign lands, travel or new ideas.
- Rahu in the 10th houseIn the 10th house of career Rahu is ambitious and visible: the classical texts give renown, a rapid rise and fearlessness in public life, with the risk of a sudden fall if ethics slip; modern practice adds politics, technology, media and foreign companies.
- Rahu in the 11th houseRahu in the 11th is hungry for gains and usually gets them: the classical texts describe large income, wealth from many or foreign sources, influential friends and ambitions fulfilled.
- Rahu in the 12th houseIn the 12th house of expense, sleep and foreign lands Rahu is read as heavy spending, restless sleep, hidden opponents and a pull toward settling abroad — which is often where its success lies.
- Chant the Rahu mantra: Om Bhraam Bhreem Bhraum Sah Rahave Namah. Sit facing east after sunrise — Saturday is the strongest day for it. Chant 5 malas a day (540 repetitions), keeping count on a 108-bead mala. Keep it up for 40 days without a break — that completes the traditional 18,000.
- Give a Rahu donation. Give urad dal, blue cloth, blanket on Saturday, before noon. Offer it to someone the world overlooks, or to anyone in genuine need. Give quietly, in person, without expecting thanks.
- Daily practice for Rahu. Keep silver or elephant motifs at home; avoid second-hand items in the bedroom. Keep it up every day for 40 days — consistency is the remedy.
Which mahadasha you are in, and when Rahu mahadasha begins or ends for you, depends on the Moon's nakshatra at birth. The dasha calculator gives every period with dates.
