Significance

Astrological significance
Onam is set by the Malayalam solar calendar and peaks on the day the moon is in the Thiruvonam (Shravana) nakshatra during the month of Chingam. This nakshatra-based timing is why Onam is anchored around late August to early September each year rather than swinging widely. It marks the harvest season in Kerala.
Month: Bhadrapada · Timed to the Thiruvonam nakshatra in the Malayalam month of Chingam — a star-based (nakshatra) reckoning rather than a simple lunar tithi.
