Karadaiyan Nombu or Savitri Nombu is a vratham / vrat observed by TAM-BRAMs on the last day of Maasi masam and first day of Panguni masam of Tamil calendar which is 14th March of every year. Married women worship Goddess Gauri or Parvathi or Shakti for marital bliss and better health of husband and children. Unmarried girls perform the vratham to get ideal person as their husband. Karadaiyan Nombu is similar to that of sowbagya Gouri vratham or Gauri Tritiya vratham of Andhra Pradesh and Karnataka, Gangaur vrat of Rajasthan, Jyesta gouri Vrat of Maharashtra, Jitiya Puja of Bihar, Karva Chauth of all other North Indian states. On this day, married women (in their traditional 9 yard saree called madisar) change their thirumangalya charadu (thread) and tie sacred yellow thread around their neck during the auspicious time of the day and unmarried girls tie only the sacred yellow thread. While changing the thirumangalyam charadu the following sloka is chanted:
Throram Krishhnami subhake saharitham
Dharami aham bharthu
Ayushya Sidhartham supreethabhava sarvadha
In my family, we normally fast till the thread is changed and eat only the neivedhyam prepared for the pooja which is called karadaiyan nombu adai.
