Although Onam is a global Hindu holiday, its origins may be traced back to the Malayali people of Kerala, India. Although Onam is predominantly a Hindu holiday, some non-Hindu Indians occasionally mark it as a cultural occasion.

When is Onam?
In the month of Chingam, Onam is celebrated over ten days. The dates of the celebration vary from year to year because they are determined by the solar and sidereal Malayalam calendar.
