The Puzzling, yet Perplexing Activation of Mahadasha and Antardasha Unveiled

Updated: Apr 12


In BPHS (Brihat Parashara Hora Shastra), many different dashas are introduced to us by Maharshi Parasahara but the Sage clarifies that amongst all of them, Vimsottari Dasha system is the most appropriate for the general population to make predictions. This dasha system has Kritika Nakshatra as the starting point and the dasha lords come in the following order: Sun (6 years), Moon (10 years), Mars (7 years), Rahu (18 years), Jupiter (16 years), Saturn (19 years), Mercury (17 years), Ketu (7 years) and Venus (20 years). To find the starting point in this dasha system for a given birth chart, we need to find how much displacement Moon has made in a given Nakshatra at birth. For example, let’s assume a native was born with a Moon positioned in Aries midway into the first Nakshatra Ashwini. Since Ketu is the lord of Ashwini and Moon displaced halfway into Ashwini Nakshatra, the dasha system will start midway in Ketu dasha for the native and they will have 3.5 years left in Ketu dasha before moving to Venus dasha. Once Venus dasha is completed, the dasha system will loop back to Sun dasha.


Now that we have a clear understanding of how Vimsottari Dasha system works, let’s look into when a dasha period starts to show its results. This might sound counterintuitive but when a given dasha starts, the results of the dasha do not seem to manifest right away. Before we go any further, I would like to introduce the reader to some concepts.

In this article, I will hereon refer to dasha as Mahadasha. The sub-periods of a Mahadasha are called Antardasha (or Bhukti). The sub-sub-periods of a Mahadasha have different names like Pratyantar Dasha but those terminologies will not be necessary for the understanding of this article. We will use the Jagannatha Hora software to compute birth charts. This software is free of charge and was created by P.V.R. Narasimha Rao. You can download the software by going to his website:

As soon as a Mahadasha starts, the Mahadasha lord will be activated in all sub-periods. For instance, let’s say Jupiter dasha just started. From Mahadasha to all sub-sub-periods, Jupiter will be active. The following illustration will give a visual of what the start of a Mahadasha looks like.

In this figure, Jupiter Mahadasha starts on 2060-10-25 at 6:54 AM. At that moment, the Vimsottari Dasha system will be at Jupiter/Jupiter/Jupiter/Jupiter/Jupiter/Jupiter time period (or in short format, Ju/Ju/Ju/Ju/Ju/Ju). As you can see, in all sub-periods Jupiter is activated. In this case, Jupiter is the base lordship in all 5 sub-periods.

In the same logic, as soon as an Antardasha starts, its lordship will be activated across all sub-periods to it. For instance, let’s say Mercury Antardasha started in Saturn Mahadasha, then all sub-periods following Mercury Antardasha will have Mercury activated. The following illustration will give a visual of what the start of an Antardasha looks like.

In this figure, Mercury Antardasha starts on 2079-10-29 at 4:03AM. At that moment, the Vimsottari Dasha system will be at Sa/Me/Me/Me/Me/Me time period. As you can see, in all sub-periods following Mercury Antardasha, Mercury is activated. In this case, Mercury is the base lordship in all 4 sub-periods following Mercury Antardasha.

Mahadasha and Antadasha Activation

After researching on Mahadasha and Antardasha for some time, I realized that they both start to show their results as soon as there is only one sub-period left that hasn’t changed its base lordship in the time period.

So, if we refer back to the Jupiter Mahadasha example, when Ju/Ju/Ju/Ju/Ju/Ju time period moves to Ju/Ju/Sa/…, results of Jupiter Mahadasha will start to show because only one sub-period of Jupiter is left unchanged. As for the Mercury Antardasha example, when Sa/Me/Me/Me/Me/Me time periods shifts to Sa/Me/Me/Ke/…, results of Mercury Antardasha will start to become apparent because only one sub-period of Mercury was left unchanged. We will go through some charts to demonstrate this finding.

Chart Analysis

Justin Trudeau

Justin Trudeau is the current Prime Minister of Canada. He was born on 25 December, 1971 at 9:27PM in Ottawa, Ontario (GMT-4) (45N25, 75W42). The following is his Rashi chart and Vimsottari Dasha.

On November 16, 2022, China’s President Xi Jinping accused Justin Trudeau of leaking information of a conversation they had together to the media. At that time, it was not very clear what the leak was exactly. But over time, it was said that China somehow interfered in the Canadian PM Elections and manipulated the results in the past. The investigation is still ongoing, but the current situation is not looking good for Justin Trudeau.

On 2022-11-06 at 9:41AM, Mars Mahadasha started for Justin Trudeau and the time period was Ma/Ma/Ma/Ma/Ma/Ma. On 2022-11-14 at 10:31PM, the time period changed to Ma/Ma/Ra/Ra/Ra/Ra. As soon as there was only 1 sub-period left unchanged, Mars Mahadasha started showing its results.

Mars is 4th and 9th lord, a powerful Yogakaraka for Leo Ascendants but here it is placed in 8th house and conjoined with 12th lord Moon. Luckily, 5th and 8th lord Jupiter is aspecting 8th house. Thus, there should be some relief soon. But it is clear that Mars Mahadasha will cause trouble to Justin Trudeau.

Volodymyr Zelenskyy

Volodymyr Zelenskyy is the current President of Ukraine. He was born on 25 January 1978 at 2:00PM in Krivoy Rog, Ukraine (GMT+3) (47N55, 33E21). The following is his Rashi chart and Vimsottari Dasha.

In Spring (October) 2021, Russian troops started to come near the Ukrainian border to conduct training exercises supposedly. In November 2021, satellite images were showing near 100,000 troops near the border. On February 24, 2022, Russian forced invaded Ukraine with missiles and attacked major cities in Ukraine.

Volodymyr Zelenskyy’s situation perfectly illustrates how Mahadashas and Antardashas give results. The Saturn Antardasha, in Moon Mahadasha started on 2022-01-31 at 6:38PM and the time period was Mo/Sa/Sa/Sa/Sa/Sa. On 2022-02-14 at 9:11PM, Mo/Sa/Sa/Me/Me/Me time period started (one sub-period of Saturn Antardasha left unchanged) which is when Saturn Antadasha started to give results. Ten days later, the invasion started. Moon and Saturn are 2nd and 12th from each other in his Rashi Chart. This combination creates losses and sorrow. Saturn and Moon together represent Masses, hinting the Russian troops at the border. As soon as Mo/Sa started to show results, the invasion started.

Joe Biden

Joe Biden is the current President of the United States. He was born on 20 November 1942 at 8:30AM in Scranton, Pennsylvania (GMT-4) (41N25, 75W40). The following is his Rashi chart and Vimsottari Dasha.

During the 2020 election campaign for President of the United States, specifically in March-April 2020, Joe Biden had to face sexual assault allegations coming from Tara Reade, a former member in Joe Biden’s U.S. Senate Office. This was definitely looking bad for Joe Biden’s campaign. At that time, Joe Biden was going through Jupiter Mahadasha and Mars Antardasha (Ju/Ma). Mars is Lagna lord and 6th lord placed in 12th house with 8th and 11th lord Mercury. Mars being Lagna lord placed in 12th house conjoined to 11th lord mercury explains how his reputation got stained at that time. Lagna lord represents self, 12th house represents conjugal life and 11th house represents reputation in society.

On May 22, 2022, the lawyer representing Tara Reade, Douglas Wigdor announced that he was no longer representing her. The whole accusation just disappeared because it came to light that she had lied in the past under oath. Joe Biden then went on to win the elections. On 2020-04-22 at 7:07PM, Ju/Ra/Ra/Ra/Ra/Ra time period started. On 2020-05-12 at 8:15PM, Ju/Ra/Ra/Ju/Ju/Ju time period was active. Ten days later, the sexual assault accusation dissolved, and Ju/Ra time period ends up helping Joe Biden to win the U.S. elections. Jupiter is exalted in his chart and Rahu is positioned in 10th house Leo representing his career. Rahu’s depositor Sun is placed in Ascendant conjoined with 7th lord Venus and aspected by exalted Jupiter. This is a powerful combination for politicians.

Anonymous Native

Native’s name and birth details is kept anonymous to protect their privacy. The following is their Rashi chart and Vimsottari Dasha.

In September 1997, they were falsely implicated in a legal case. At that time, native was going through Rahu Mahadasha and Jupiter Antardasha (Ra/Ju). The case went on for several years until March 2013. In March 2013, the court declared that the native was guilty. He immediately appealed in High Court and deliberately delayed the hearing until now.

Jupiter dasha started on 2012-07-26 at 8:58PM and the time period was Ju/Ju/Ju/Ju/Ju/Ju. On 2012-11-08 at 4:23PM, Ju/Ju/Sa/Sa/Sa/Sa time period started. Four months later, in March 2013, the native gets a verdict from the court as soon as there is only 1 Jupiter sub-period left unchanged. Rahu Mahadasha is an illusionary time period and Rahu’s depositor Venus is debilitated and afflicted by Mars and Saturn. Thus, Rahu Mahadasha turned out to be a very tough period for the native and the case never reached a verdict in it. On the other hand, Jupiter Mahadasha is the enlightenment time period where the truth is known. As soon as the time period had 1 Jupiter sub-period left unchanged, Jupiter Mahadasha’s results started to appear and brought a verdict for a case that was left open for almost 6 years!


To conclude, it is clearly noticeable that Mahadashas and Antardashas do not display their results right away. Just like how Russia needed time to prepare their troops near the Ukrainian border before attacking the country, the Mahadashas and Antardashas need some time before manifesting their results. Mahadashas and Antardashas will show their results as soon as their lordship only remains unchanged in 1 sub-period.


I would like to thank my guru Muthu Vijayan Elango for helping me and giving me important suggestions while writing this article.
