Ganesha Chaturthi is celebrated to commemorate the birthday of the elephant-headed God of Hindus. People of this community have great faith in the potency of Lord Ganesha. He is also called Vinayaka or Ganapati and is the representation of the supreme power of the almighty. Vinayak Chaturthi in Kerala in 2018 will be celebrated on 25th of August.
There is a difference in celebration of Vinayaka Chaturthi in Kerala and that of in other states. This difference is because it is observed during Shukla Paksha in Chinga Masala whereas in other states it is celebrated Bhadrapad Shukla Paksha. But, when there is no Adhika Masa in the lunar calendar then Vinayaka Chaturthi is celebrated on same date in Kerala and other regions. Since, Kerala Malayalam calendar is a solar calendar so it does not have an Adhika Masa. Once in every three years, there occurs a difference between the celebration date of Ganesha Chaturthi in Malyalam calendar and other Hindu calendars.
In certain regions of the state of Kerala, Ganesha Chaturthi is also observed for a period of 10 daya like in other states. On this gigantic statues of Lord Ganesha are established at various public places and sometimes also in homes.
