WHAT IS SHASTIPOORTHI?
shastipoorthi means completing cycle of 60yrs.

Astrological .

Jupiter and Saturn are the two most important slow moving planets in Indian astrology . Jupiter completes one cycle around Sun in 12 years and Saturn does so in about 30 years. The lowest common multiplier for the two numbers is 60.

So, the age of 60 is important because at this age , Jupiter and Saturn return to the same signs (Rashi) where they were at the time of birth after completing 5 cycles of Jupiter and 2 cycles of Saturn .
