Upakarma or Avani Avittam is an important religious event for brahmins belonging to the four Vedas namely Rig, Yajur, Sama and Atharva Vedas.
· Rig Veda Upakarma is on the day when Shravana star falls in Shravana month.
· Sama Veda Upakarma is on Hastha nakshatra in Suklapaksha Bhadrapada month.
· Krishna Yajurveda brahmins perform Upakarma rituals on the day Avittam nakshatram falls in Shravana month.
· Shukla Yajur Vedic brahmins do it on the Pournami when the full moon lasts till afternoon.
· Atharva Vedic brahmins perform on the day when Pournami is there during sunrise.
Upakarma is the ritual when Brahmins, Kshatrias and Vaishyas change their upanayana thread and take a new one accompanied by rituals. When there is an eclipse, the date for observing Upakarma changes for Yajur Vedic brahmins.
Since there is an eclipse on the Full Moon Day in Aadi (7.8.2017), it has been decided by the pandits and scholars that the day has Grahana dosham and the Yajur Vedic brahmins can perform their Upakarma on Avani Full Moon Day.
So, Upakarma date for Yajur Veda has been decided as 6.9.2017.
In 2017, in the Hevilambi year, the following are the dates for observing Upakarma as decided by pandits and scholars.
Let us follow our traditional rituals to keep up our religiosity and stay in tune with our ritualistic performance.
