By Chathayam, Onam has changed character again.
The day is widely observed as Fourth Onam. The central Thiruvonam rituals have passed, but Kerala has not finished celebrating. Public performances, local events and family gatherings continue into the days that follow.
Why Chathayam deserves its own story
When Onam is reduced to one date on a holiday calendar, Chathayam is easy to overlook. But including it gives a more accurate picture of how festivals actually work: there is preparation, a climax and then a period of continuation.
For families abroad, this matters because many community Onam programmes naturally fall after the main day. The cultural season remains alive even when the official holiday has ended.
The next chapter is public celebration
After Chathayam, MalluMetro’s Onam Journey moves toward two highly visible Kerala events: Pulikali in Thrissur and the Aranmula Vallamkali. These are not simply “extra days” of the same household ritual. They are major cultural traditions with their own histories.
That is why our series continues beyond the usual ten-day summary.
Onam follows the Malayalam calendar and nakshatra timings, so some 2026 day labels span parts of two Gregorian dates. MalluMetro anchors the series to Kerala Tourism’s official Thiruvonam date of 26 August 2026 and clearly labels the extended calendar where needed.
