I don’t know my exact birth time so there is a problem that i don’t have my kundali. What can i do? Is there any solution to get birth chart or kundali without accurate time? I want to make it for marriage and career purposes.

I came from poor family and my parents don’t know my exact birth time. So they never make my kundali or consult any jyotish.Currently i am facing difficulties in career. I am unemployed and also have marriage problems… Is there any chance to get birth chart or kundali without accurate birth time..
