Donald W. Patten (1929-2014) was an American researcher and keen supporter of catastrophism. He was also a dedicated creationist. His cosmological theories were comparable to those of Velikovsky, who claimed that some of the planets in our Solar System were rearranged within the memory of man. This reorganisation involved a number of damaging close encounters by some planets with the Earth. While Velikovsky was to a great extent focused on the movements of Venus, Patten was more concerned with the activities of Mars.
Stuart Harris noted in a 2017 paper(c) that “Donald W. Patten modeled flybys of Mars as a fIxed sequence that alternated spring and fall, spaced 108 years apart. He sequenced flybys from 701 to 1404 BCE using historical records. Flybys alternated between the night of March 20-21 on odd years, and during the day of October 24 on even years.”
Harris’ paper “extends Patten’s methodology to March 7137 BC by recognizing that the 108-year interval was not constant but occasionally increased in increments of four years. Two important milestones are March 3161 BC, the Biblical Flood, and March 3761 BC, the start of the Hebrew calendar.”
Patten wrote a number of books and papers, two of which were with Samuel R. Windsor entitled The Recent Organisation of the Solar System, and The Mars-Earth Wars, which are also available online(a)(b).One of the consequences of this ‘reorganisation’ and encounters with our neighbouring planets was a lengthening of our solar year from 360 to 365+ days(d)!
It is interesting to compare Patten’s ideas with the the 366 day year proposed by Alan Butler in The Bronze Age Computer Disc , based on his interpretation of the Phaistos Disc. His explanation has been endorsed by Sylvain Tristan(e).
>A related book, The Mystery of the Great Flood Confirmed,  by Elsar Amos Orkan envisages an ancient interaction between the Earth, Mars and our Moon around 8000 BC. However, the principal objective of the book is to argue that our current global warming is the result of a shortening of the distance between the Earth and the Sun!
Patten & Windsor also produced a paper(f) titled Catastrophic Theory of Mountain Uplifts that they claim resulted from close encounters with other planetary bodies, such as Venus and Mars!<
