In Kerala, Ganesh Chaturthi is more popularly known as Vinayaka Chaturthi and it is celebrated during Shukla Paksha Chaturthi in Chingam Masam. In Malayalam Calendar, Chingam is the first month of the year and coincides with Simha Solar month in other calendars.
In other states, Ganesh Chaturthi is observed during the Bhadrapada month based on the lunar calendar. As Malayalam calendar follows a different rule to observe Vinayaka Chaturthi, it might fall one month before Ganesh Chaturthi observed in other states. However, it happens rarely. Few years in which Vinayaka Chaturthi is observed one month before Ganesh Chaturthi are 2004, 2012 and 2015.
