The prospective groom was born on 8th August, 1972 at 23:10 hours IST at Mumbai, while the prospective bride was born on 10th July, 1975 at 21:00 hours IST at Kolkata. Though there is a match of 29 out of 36 points in ashtakoot guna milan, however, there is a Vimshotari antar dasha change in both the natal charts in an interval of about 4 months, that is, the prospective groom’s Sun dasha is changing to Moon dasha on 17th July, 2022 while the prospective bride’s Venus mahadasha is changing to Sun Mahadasha on 30th November, 2022.
Does this dasha change in 2022 within a span of 1 year in both the natal charts predict death of one of the prospects, in case there is a marriage between the two? If yes, then are there any remedies to avoid the malefic effects of the dasha change?
I feel I do not understand your Question at all, we are presently in 2015. What is about the year 2022.
If what you want to know that in 2022 the dasha of the boy and girl are changing within 4 months , then is it good or bad for their health. First of all where did you read that the dasha change as suggested by you is bad. Some dasha from birth dasha are bad, but that is a totally different concept.
Secondly just want to let you know it is the dasha of functional malefic planets that will be bad, but death will be in the period of Maraka dasha and bhadaka planet has to be involved. Therefore if you feel that a change in dasha in the span of 4 months will bring death to the boy or the girl then it is not there.
