Upakarma Variation
According to Nirnaya Sindhu following conditions should be taken care for deciding the date of upakarma
- Rigveda Upakarma:Should be done on the day in shraavana where shravana is the star and spans at least from sunrise to mid day.But not in Uttara Ashadha if present during sunrise.
- Samaveda Upakarma: Should be done on hasta nakshatra on bhadrapada shuklapaksha
- Krishna Yajurveda: i.e. Taittiriyas & Maitrayanis should do on shravistha, dhanistha,(avittam in Tamil),on shraavana month,whether it falls on purnima yukta Pratipada (Pratipat)during sunrise (Telugu- paadyami) or prathama.
- Shukla Yajurveda: i.e. Vajasaneyi Kanvas and Madhyandinas do in purnima day if purnima is present up to evening.But if punima and pratipada both are present on next day(para viddha) they should do on previous day when chaturdashi stays in day and then purnima comes after mid day(purva viddha).Under no condition they should do/avoid doing in krishna paksha pratipat or broadly speaking they should finish upakarma before approach of krishna paksha.but they postpone upakarma to the next day if purnima is having Uttara Ashadha nakshatra.
- Atharva Veda: They do on the day when purnima lasts during sunrise.(udaya vyapini tithi)
