It would depend on which god you are referring to but calendars are the invention of man not a god.
Answer
This answer will depend upon your understanding of gospel princpiles. It may therefore be contrary to your way of thinking. All living things have intelligence, and as intelligence has always been and is there to be used in some form or other. As the scriptures say that God says that he is without beginning nor end, we have to believe that he was created from some other God as were all Gods before Him. He was created first as a spirit from spirit matter into which was placed His intelligence. I cannot give an acceptable answer to how this was done, except that it may have been through the same process that we are born only through Godly parents, He as a spirit child first.
Like all of us he had to gain a body of flesh and bone and go through the same experience(s) that we are going through. Just as His son Christ did.
To ask what does God's year begin with, no deffinate answer can be given unless the above answer I have given can be acceptable. To say that God says that he is without beginning nor end is correct, but as an intelligence first rather than a person of flesh and bone.
I have no doubt that some will give answer to my answer, but so be it.
That would depend upon which religious calendar is consulted. In Judaism, the religious new year begins on the first of Tishrei, which was the day on which Adam was created, and which occurs in September or October (Varying from year to year in the Gregorian calendar). See also:
