Today, (September 16, 2013) is Sravanam Dwadasi. It is usual to fast on Ekadasi and do Paaranai (break the fasting) on dwadasi thithi. But during the Sravana Dwadasi which is very auspicious and occurs once year, it is recommended to perform fasting on that Sravana Dwadasi day and do Paaranai on trayodasi, the next day. For this year (Vijaya varusham):
- Ekadasi – Sunday September 15, 2013
- Sravanam Dwadasi – Monday September 16, 2013 [Fasting is highly recommended]
- Sravanam Trayodasi – Tuesday, September 17, 2013 [Do the paaranai]
Today is very auspicious as it also happens to be Sri Hayagriva Jayanthi and Sri Vamana Jayanthi.
