Arre but this is Mahapooja na! Ik it comes every month my grandma and all used to take vrat but this is something special.
Maybe Sujz don't have any idea about Mahapooja. But I think people do vrat etc on different ekadashi of month.
But still if it's first day of the month then how can be Ekadashi after 2 days. I am confused.
