Karthik and its deity association

In Hindu tradition, names are often dedicated to a deity to invoke their blessings throughout the child’s life. Karthik is associated with Lord Murugan / Karthikeya.

Naming ceremony (Namakarana Samskara) note

In Hindu tradition the formal naming of a child is the Namakarana Samskara, performed on the 11th, 12th or 16th day after birth. The name is whispered three times into the baby’s right ear by the father or family priest, while flowers and rice are offered to the family deity. Karthik fits this ceremony naturally — the Devanagari spelling कार्तिक preserves the correct sacred phonetics.
