There is great importance of Muhurta in oath taking ceremony of Prime Minister/Chief Minister and other high dignitaries. Cancer Lagna rising in the ascendant is generally not recommended for oath taking ceremony.But ascendant lord aspecting lagna is good.
As per available sources his natal Moon is in Gemini(15 December 1970, Purba Medinipur) .Sign of Lagna falling in second house of natal Moon is not good.
Lagna Lord Moon and its dispositor Saturn both are not friends to each other, but present West Bengal government is not a coalition government. Hence no problem.
Eighth house is in Rahu-Ketu axis but is aspected by benefic Jupiter. In Shadbala Calculation Lagna Lord is stronger than eighth lord. Hence there is no danger to longevity of the government. But opposition and ruling parties will never be co-operating each other.
Sun is in its sign of exaltation i.e Aries. It is also in uttarayana and strong in shadbala. Moon is also strong in shadbala and in a friendly sign Capricorn. Tenth house has medium strength. Malefics Saturn and Mars are in trikona. Badhakadhipati Venus is in a badhaka place. Moon and combust Mercury are in kendra.
In a good muhurta eighth house should be vacant. But eighth house is in Rahu-Ketu axis and is aspected by Jupiter. Lagna should not be in papakartari Yoga.But there is ketu in the second house. A malefic in second house indicates internal bickering.
Nakshatra on the day of oath was Sharavan. According to Sh. K K Joshi Sharavan nakshatrais consired good for oath taking. Tithi was krishna saptami and the day was Saturday. Tithi is not a taboo,but Saturday is not good. Unfortunately malefic planets are strong in shadbala.
As far as panchang prameters are concerned all parameters are not good. It indicates mixed results .Suvendu Adhikari will either not complete his tenure as chief minister of West Bengal or face many serious problems in running first BJP government of West Bengal.

Oath taking chart of Subendu Adhikari is given below:-

Above chart indicates that second house is in Rahu-Ketu axis and is aspected by Mars. Second house mainly indicates financial condition of the state and the government will have to manage economy of the state most cautiously and many austerity measures will have to be taken by Suvendu Adhikari government. Condition of banks will deteriorate and some bank may fail.
Third house is aspected by Mars & Saturn whereas ninth house is occupied by Mars & Saturn. Hence there is affliction along three nine axis. Someone may try to disrupt communication system in the state and there will be communal riots or any one community will try to disrupt communal harmony of the state. Relations with neighbouring country will not be good. All this will negatively affect the internal and international trade of the state. Accidents will increase. There is possibility of famine and epidemic. Functioning of the judiciary will be adversely affected due to internal disturbance in the state.
There is aspect of Rahu and Mars on the twelfth house making it afflicted. Affliction on both sides of the lagan again confirms that Suvendu Adhikari will not be able to complete his tenure.
Presence of Moon in seventh house indicates that there will be increase in number of marriages and public ceremonies. Women will be suitably honoured. Suvendu Adhikari government will be able to bring improvement in condition of women and children in society. Some legislation will be brought for their betterment. But Suvendu Adhikari will find many obstacles in bringing improvement in the condition of women due to aspect of Saturn on Venus.
Harmony, peace and prosperity will increase .Communal and religious disharmony, however, will prevail.
Sun in tenth house is good but it has combination with third and twelfth lord Mercury and has ninth aspect of Ketu on it. The people in high authority will not be happy. Some discomfort among a section of people and political circles seem possible. There is possibility of scandals in high places.
There will be huge expenditure on charity type schemes and educational institutions. Aspect of Rahu and Mars on ninth lord in twefth lord show that spying by enemies and subversive activities by them will be on the rise due to which high dignitaries and well placed persons will suffer.
In Simhasan Chakra Moon is in simha nadi. It is placed in seventh house as lagna lord. It has aspect of Saturn on one side and Saturn is with Mars. On other side Rahu is present. It means that he will have to work with constraint and his powers will not be absolute. Saturn is in patta nadi. Saturn is not only the planet of masses and democracy but is also the significator of death and destruction. It means that public will have to remain in discipline and there will be some deaths and destruction also. Unfortunately Jupiter is also in patta nadi .It means that Suvendu government and his council of ministers will have only limited protection. It is also an indication of his not completing his tenure. Venus in simhasan nadi but in mrigsira nakshatra of Mars indicate that there may be physical injury to some woman minister.
In Rashi Sanghatta Chakra there is opposition of Sat-Mars combination with Sun-Mer combination.As per Parashari Astrology there in no such aspect but they are in two-twelve postion to each other. Similarly Venus -Rahu opposition which is there in Rashi Sanghatta Chakra is absent in Parashari Astrology. Thus indications of Rashi Sanghatta Chakra confirm which we have cocluded in above discussion.
In a nutshell Suvendu Adhikari government will take many positive steps for overall development of the state but will not be able to complete his tenure perhaps due to personal reasons.
