Why is today the begining of a new year ?

I met a learned man today. This is the conversation between me and him (My questions are in BOLD, and his responses follow).

Sir, if today is the beginning of a new year, what was it 4 month ago?

He said "Our year is based on PRINCIPLE and not PERSONALITIES. For us time begins with sunrise and not sunset. We are BHARATIYAS (bha=Luminous Light & ratiya=one who plays with it)

Sir, what is UGADI?

He said "UGADI = YUGA + ADI". He said it was important to describe the concept of "time" according to bharatiyas. I have given the gist (look at the picture for reference)

• There is 1 immaculate, immutable, impersonal, omnipresent, unchangeable PARAMATMA
• Even the gods are the creation of paramatma
• The highest portfolio in paramatma's domain is held by Brahma, followed by Indra and later by Humans.
• 1 day of Brahmas life = 14 Indra's Life span.
• 1 Indra's Lifespan = 71 chaturyugas (i.e. 4 YUGAS). WE are presently in "KALIYUGA".
• 1 year of Indra = 360 Human Years

ADI is the beginning of everything, even before the yugas, i.e. the PARAMATMA

So UGADI is the celebration of "remembering" the PRINCIPLE that existed even before the yugas; the immaculate, immutable, impersonal, omnipresent, unchangeable PARAMATMA.

Sir, Why two ugadi's, one today and one last week?

Today is Suryamana Ugadi and last week was Chandramana Ugadi. Suryamana Ugadi takes SUN as the primary factor for calculations but in Chandramana Ugadi even the moon is given importance in calculations.
