Sankatahara chaturthi or Sankashti is very auspicious for worshipping Lord Ganesha. Devotees observe fast throughout the day. In the evening, Ganesha is worshipped with darbha by chanting stotras like Ashtotram, Ganesha Atharvaseersha, Sankatanashana Ganesha stotras and conclude the pooja by offering modaks/vundrallu and break their fast after sighting moon.
