I have numerous vehicles, boat, pwc, motorcycle etc which all get very low hours/miles. Seems like I am always changing oil in something.
I did an extensive search and I could find nothing that states it is ok to go beyond one year for oil changes. Many articles say we change our oil with too few miles. But one year seems to be the magic time limit.
