That is a good thing. On the first day of the Upanayanam, the child will begin Samitadhanam. From that day morning and evening, they must continue to perform Samitadhanam. The most important thing is to protect the sacred fire (Agni) without letting it go out. You must protect that fire for three days and perform Samitadhanam twice daily. After the ritual, an Akshata (sacred rice) blessing is given. These are all 10-minute tasks. One needs the skill to keep the fire alive; your priest (Vathiyar) will guide you on this. After that, on the morning of the fourth day, a ritual called Palasha Karma is performed. Until that day, items like the Palika (sprouting seeds) and Dandam (staff) are kept. Related pujas are performed on that day. These are 5-minute tasks. Finally, there is a ritual called Thandu Neer. The Dandam is given an Abhishekam. It is not 5 days, but a 4-day Upanayanam. On the fourth day, after Thandu Neer, the Palika is dissolved in water, and it concludes auspiciously. Doing a 4-day ceremony is not a big deal; the challenge is protecting the fire. This is mentioned in the Sutras. It says the fire must be protected for 3 days, the Palika preserved, and the Dandam invoked with pujas. Performing four days of upanayana samskara as prescribed in the Sutras ensures it is considered complete and is beneficial.
