Ashtami Rohini, also popular as Janmashtami or Sri Krishna Jayanthi, is the most celebrated festival in Guruvayur Devaswom or Sri Krishna Temple Guruvayur. In 2017, Ashtami Rohini date is September 13.
It attracts more than one lakh devotees from all across the globe.
But in North Indian states, in Andhra Pradesh and Karnataka, Janmashtami date differs with Kerala. But this year, Janmashtami is celebrated on 5th September throughout India.
As per the Malayalam calendar of Kerala, Ashtami Rohini (Birthday of Lord Krishna) falls in Chingam month.
Devotees book their tickets in advance to offer ‘Unniyappam Naivedyam’ (Appam and Payasam – the special offering offered to Lord Krishna on Ashtami Rohini). They will collect offered Unniyappam from the temple after ‘Athazhapooja’.
