Kanakabhishekam
To be eligible for Kanakabhishekam (literally 'to be showered with gold') the concerned person should have his first-born as a son (Seemantha Putra) who is alive; that son should also have his Seemantha Putra alive, and he too be blessed with a living son born as his first child. This is the requirement for those living a house-holder's life. For ascetics, and the renounced who are religious heads, there are other rules. The basic point, of course, is that the person concerned has lived to be past 80 years. It is sometimes stipulated that the person should have lived to have seen a thousand full moons. Sahasrachandra Dasanam is likely for people between 80 and 83 years of age.
