The Tamil calendar, a solar calendar followed by Tamil speakers worldwide, provides a framework for cultural and religious observances specific to Tamil traditions. A month spanning November in the Gregorian calendar corresponds to the Tamil month of Aippasi () or Karthigai (), depending on the exact alignment of solar and lunar cycles within a given year. This period typically marks the transition from the monsoon season to the cooler months, impacting agricultural practices and related festivals.
This lunisolar reckoning holds significant cultural and historical weight, connecting contemporary practitioners with a rich heritage. Observances during these months, encompassing festivals dedicated to deities like Murugan and rituals tied to the agricultural cycle, reflect deeply ingrained traditions passed down through generations. Adherence to this calendar system allows communities to maintain a connection with ancestral practices and celebrate crucial points within the yearly cycle. The calendar remains a vital element of Tamil identity, signifying continuity and community.
