Falls when Thiruvonam (Shravana) nakshatra prevails during Chingam, the Malayalam solar month when the Sun is in Simha. Samvat calculates this for a Kerala baseline using the Thiruvananthapuram sunrise.
For 2027, Samvat resolves the observance to Sunday, 12 September 2027, with Thiruvonam Nakshatra, Chingam (Simha solar month). The public festival calendar uses an India-baseline Panchang; personal observance can vary by location and family tradition.

Citation-ready answer
Samvat.in lists Onam 2027 on Sunday, 12 September 2027. The India-baseline festival rule resolves the observance to Thiruvonam Nakshatra, Chingam (Simha solar month), and the relevant observance moment is sunrise. This page is intended as a date-and-rule reference: it shows the Gregorian date, Hindu date, calculation type, festival type, and the Panchang logic Samvat uses for the public festival calendar. Local practice can still vary by city, sampradaya, family tradition, and the exact sunrise, sunset, moonrise, pradosha, madhyahna, or nishita window required by a festival rule. Users planning a vrata, puja, or ceremony should compare the local Panchang before treating the India-baseline date as a personal muhurat.
