 She is not to be confused with the Kali-yuga, which is spelled similarly yet holds a different meaning.The Kali-yuga is presented as a threat to Mother India, with pictures from the nineteenth century depicting the age as a "ferocious meat-eating demon" in comparison to India's depiction of "a cow giving milk to her children".The largest annual festival associated with the goddess is Durga Puja celebrated in the month of Ashvin (September–October), where nine manifestations of Parvati ("Navadurga") are worshipped, each on a day over nine days.
