Antardasha Calculator
The Antardasha (also called Bhukti) is the second level of the Vimshottari Dasha system — a sub-period within each Mahadasha that refines the broad planetary themes into more specific, time-bound influences. While the Mahadasha sets the overall chapter of your life, the Antardasha determines the specific plotline within that chapter, changing every few months to a few years. Kaala's Antardasha Calculator computes all nine Antardashas within each of your Mahadashas, showing exact start and end dates for every sub-period. Within a 20-year Venus Mahadasha, for instance, you will pass through Venus-Venus, Venus-Sun, Venus-Moon, Venus-Mars, Venus-Rahu, Venus-Jupiter, Venus-Saturn, Venus-Mercury, and Venus-Ketu Antardashas — each bringing a distinct flavor to the Venus period. For practical prediction, the Mahadasha-Antardasha combination is the most commonly used timing tool in Jyotish. When a Jyotishi predicts that 'career advancement is likely in 2027,' that prediction is typically based on a favorable Antardasha activating within the current Mahadasha. Understanding your Antardasha sequence allows you to anticipate shifts in themes, opportunities, and challenges at the year-to-year level.

How Antardasha Duration Is Calculated
Each Mahadasha contains nine Antardashas, one for each planet, in the same Vimshottari sequence. The Antardasha durations are proportional — they are calculated by multiplying the Mahadasha duration of both the major and sub-period rulers and dividing by the total 120-year cycle. For example, the Venus Antardasha within Jupiter Mahadasha lasts (20 x 16) / 120 = 2 years and 8 months.
The Antardasha sequence within each Mahadasha starts with the Antardasha of the Mahadasha lord itself (Venus-Venus in Venus Mahadasha) and then follows the standard Vimshottari order from that point. So Venus Mahadasha progresses: Venus-Venus, Venus-Sun, Venus-Moon, Venus-Mars, Venus-Rahu, Venus-Jupiter, Venus-Saturn, Venus-Mercury, Venus-Ketu. The starting date of the first Antardasha aligns with the Mahadasha start date.
Interpreting Mahadasha-Antardasha Combinations
The Mahadasha lord and Antardasha lord interact to produce specific results based on their natural relationship, their positional relationship in the birth chart, and the houses they rule. When the Mahadasha and Antardasha lords are natural friends (like Jupiter-Moon or Venus-Mercury), the sub-period tends to flow smoothly. When they are natural enemies (like Sun-Saturn or Mars-Rahu), the sub-period can bring friction and challenges.
The house relationship is equally important. If the Mahadasha lord is in the 10th house (career) and the Antardasha lord is in the 2nd house (wealth), that sub-period may bring career-driven income growth. If the Mahadasha lord is in the 7th house (partnerships) and the Antardasha lord is in the 12th house (separation/foreign lands), the sub-period might bring a long-distance relationship or partnership dissolution. Kaala's AI interpreter Jyothi analyzes these specific combinations in your chart for personalized Antardasha predictions.
Key Antardashas to Watch
Certain Antardasha transitions are especially significant. The Antardasha of the Mahadasha lord itself (the first sub-period) sets the tone for the entire Mahadasha — whatever themes emerge during this Antardasha will recur throughout the major period. The Antardasha of the planet ruling the subsequent Mahadasha (the last sub-period) serves as a preview of what is coming next.
The Rahu and Ketu Antardashas within any Mahadasha tend to bring unexpected events, sudden changes, and karmic intensity. Saturn Antardashas often coincide with periods of increased responsibility, delays, or health concerns that require patience and discipline. Jupiter Antardashas are generally the most supportive, bringing optimism, growth, and resolution of problems. Venus Antardashas frequently coincide with relationship developments, creative output, and financial improvement.
Using Antardasha for Event Timing
Professional Jyotishis use the Mahadasha-Antardasha combination as the primary timing framework for predicting when specific life events are most likely to occur. Marriage predictions require a favorable 7th lord or Venus Antardasha. Career promotions align with strong 10th lord or Sun Antardashas. Property purchase often coincides with 4th lord or Mars Antardashas.
To use this information practically, identify the key Antardashas within your current Mahadasha using Kaala's calculator, note their exact dates, and correlate them with the houses and significations of the Antardasha lord in your birth chart. If you are in Jupiter Mahadasha and an upcoming Mercury Antardasha is approaching, and Mercury rules your 10th house, that sub-period is likely to bring career developments. Jyothi can provide this level of analysis automatically when you request a timeline interpretation.

Frequently Asked Questions
Antardasha and Bhukti are different names for the same thing — the second-level sub-period within a Mahadasha. Antardasha is the more commonly used term in North Indian Jyotish tradition, while Bhukti is sometimes used in South Indian tradition. Kaala uses both terms interchangeably.
The Antardasha of the 7th house lord, Venus (natural significator of marriage), or Jupiter (significator of husband in a woman's chart) within a compatible Mahadasha are most favorable for marriage. The Mahadasha must also support marriage — Venus, Jupiter, or the 7th lord's Mahadasha combined with a compatible Antardasha creates the strongest marriage window.
Kaala's calculator shows the exact start and end dates for every Antardasha within your current Mahadasha. The dashboard view highlights your current Antardasha and shows the next one approaching, including which planet will take over and what themes it may bring based on its position in your birth chart.
