Today, 17 May 2013 is Ganga Saptami Ganga Pujan. Ganga Puja (Ganga Saptami, Ganga Jayanti, Jahnu Saptami) is an auspicious day to worship Ganga River or Goddess Ganga Mata. It is believed on this day, Goddess Ganga or Ganga River descended to the earth from the heavenly abode.
Ganga Aarti is the main ritual performed on this day in Varanasi (Kashi), Haridwar, Allahabad Triveni Sangam, Rishikesh, etc. This year it is even more auspicious as it also coincides with Ganga Pushkarams.
In 2013, Ganga Saptami falls in Vaigasi Masam of Tamil calendar, Edava Masam of Malayalam calendar and Jaishtho month of Bengali Panjika.
