This rather extensive publication was given, so I have been told, to every service person when they left Vietnam. I kept my personal copy, which is scanned here. In all the searching I have done for other Vietnam materials, I have found only 1 other copy, which I purchased.
The title comes from the fact that a regular tour in Vietnam for a Army soldier was 365 days. My own tour lasted only 10 months and 22 days due to the fact that I spent time stateside prior to going to Nam.
