Free Antardasha Calculator — Your Vedic Sub-Period, Live
The Antardasha is the sub-period inside your current Mahadasha — the finer timing layer Vedic astrologers consult when naming specific events. Computed from your exact birth moment, Lahiri ayanamsa, Swiss Ephemeris. No signup.
What is Antardasha?
Antardasha (also called bhukti) is the sub-period within a Mahadasha in the Vimshottari Dasha system of Vedic astrology. Each Mahadasha is divided into nine Antardashas, one for each of the nine grahas. The Antardasha sequence inside any Mahadasha begins with the Mahadasha lord itself, then continues in the standard Vimshottari order. The length of each Antardasha is calculated as (Antardasha-lord years × Mahadasha-lord years) ÷ 120. While the Mahadasha sets the theme of a chapter in your life, the Antardasha tells you which specific scene is playing now.
What your Antardasha tells you
- Combined signature of two lords — 'Saturn-Jupiter Antardasha' means you're inside a Saturn Mahadasha but currently feeling Jupiter's influence on top.
- Sharper event timing — Vedic astrologers look at Antardasha to predict when within a Mahadasha a marriage, career shift, or difficult passage actually happens.
- Why chapters feel uneven — an 'easy' Mahadasha can carry a difficult Antardasha and vice versa; the rotation is what creates variation.
- Full nine-Antardasha rotation — the rhythm of the entire chapter, past, present, and remaining.

Frequently asked
What is Antardasha in Vedic astrology?
Antardasha (also called bhukti) is the sub-period within a Mahadasha in the Vimshottari Dasha system. Each Mahadasha is divided into nine Antardashas — one for each graha — and the duration of each is calculated as (Antardasha-lord years × Mahadasha-lord years) ÷ 120. The Mahadasha sets the chapter; the Antardasha tells you which scene is playing now.
What is the difference between Mahadasha and Antardasha?
Mahadasha is the major planetary period (6–20 years) ruling an entire chapter of life. Antardasha is the sub-period inside it (a few months to a few years). Vedic astrologers consult Antardasha for sharper event timing than Mahadasha alone allows.
Which Antardasha is considered difficult?
It depends on the natal placement of the two lords in your chart. Antardashas of malefics (Saturn, Mars, Rahu, Ketu) tend to be more demanding when those planets are afflicted; benefic Antardashas (Jupiter, Venus, Mercury) tend to be easier when those planets are well-placed. Always chart-specific.
How are Antardashas calculated?
Each Antardasha's duration is (its planet's years × the Mahadasha planet's years) ÷ 120. For example, inside Saturn (19y) Mahadasha, the Mercury (17y) Antardasha lasts (17 × 19) ÷ 120 = 2.69 years. The nine Antardashas in any Mahadasha sum to the Mahadasha's total length.
What is the difference between Antardasha and Bhukti?
They are the same thing. Antardasha (Sanskrit: 'inner period') and Bhukti (Sanskrit: 'experience') are interchangeable terms for the sub-period within a Mahadasha. South Indian Vedic tradition tends to use 'Bhukti'; North Indian tradition tends to use 'Antardasha'.
