Karadaiyan Nombu or Karadayan Nonbu is a major Tamil festival which is celebrated at the time on Meena Sankranti or Sankramana. It is celebrated at the moment when Tamil month Maasi ends and month Panguni starts. Karadai is the name of a unique Nivedyam prepared on this day and Nombu means Vratham or Upavasam.
It is believed that Savitri got her husband Satyavan back from Yama, the Lord of Death on the very same day. Due to this legend Karadaiyan Nombu is also known as Savithri Vratam. On Karadayan Nonbu day women worship Goddess Gowri and offer her Karadiyan Nombu Nivedyam. After Puja women tie the sacred yellow cotton thread known as Manjal Saradu or Nonbu Charadu for well-being of their husband.
Married women observe it for long lives of their husband while unmarried girls observe it to get ideal person as their husband. On this day married women and young girls wear yellow robes and pray to Hindu Goddesses for long life for their husband or to get ideal person as their husband in the future.
The fast for Karadayan Vritham is observed from sunrise on the transition day when God Surya moves from Kumbha Rashi to Meena Rashi. Fast breaking time for Savitri Nombu might fall any time between current day Sunrise to next day Sunrise depending on time of Meena Sankramana. Please note that duration of fast depends on local Sunrise and Sankramana moment and varies for all locations.
Manjal Saradu is tied at the moment when Masi Masam ends and Panguni Masam starts. DrikPanchang.com lists the exact time to tie Manjal Saradu which is also the time of Meena Sankramana and we do it for 20,000+ cities across the globe. Meena Sankramana might occur at any time during the day and many times it occurs after midnight which might not be convenient time to perform Puja rituals. However Puja for Karadi Nombu and other rituals are observed at the exact time when Meena Sankramana occurs.
If time for Manjal Saradu falls after midnight but before next day sunrise we show it in 24+ format as Hindu day starts and ends with Sunrise.
