Frequently asked questions
Which Tamil month is September 2027?
1–16 September: Avani (ஆவணி) 16–31 and 17–30 September: Purattasi (புரட்டாசி) 1–14 (Plavanga year). A Tamil month changes with the Sun’s Sankranti, so it begins in the middle of the English month.
When does Purattasi 2027 start?
Purattasi (புரட்டாசி) runs from Friday, 17 September 2027 to Sunday, 17 October 2027 (31 days). The Sankranti is at 2:15 PM on 17 September 2027, before sunset, so the month begins that day.
Which festivals are in the Tamil calendar for September 2027?
Vinayagar Chathurthi (4 September), Mahalaya Amavasai (29 September) and Navarathri begins (30 September). Ekadashi: Parsva Ekadashi on 11 September and Indira Ekadashi on 26 September. Vrats such as Pradosham, Sashti, Karthigai, Pournami and Sankatahara Chaturthi are on their days in the table above.
Which city and which panchangam are the dates for?
By the sunrise of Chennai. The tithi, nakshatra and month dates follow the Thirukanitham (drik) reckoning, which Drik Panchang’s Tamil Panchangam also uses. Many temples and almanacs follow the Vakya Panchangam, in which a month sometimes begins a day earlier or later. For a temple or home ritual, check with your own panchangam or priest.
