On Thursday, 17th of September, the auspicious yog of planetary constellations is being made on all Pitra Amavasya. This time it is happening after 38 years. When Pitra is changing the zodiac sign on the Amavasya, the Sun is coming into the Virgo. That is, a very auspicious coincidence is being made on Surya Sankranti on Pitru festival. Earlier this coincidence was formed in 1982 and will be made again after 19 years. On all Pitra Amavasya, shraddh and donation is performed for all the fathers. The father is completely satisfied with this. The fathers who came to the earth in the air are bid farewell on this day and the ancestors leave their folk.
