I am a retired instrumentation engineer who spent most of my career in the Canadian nuclear power industry. My book, "Practical Perpetual Calendars - Innovative, Convenient and Green” by James R. Saltvold, documents unique concepts that I have developed to make standalone perpetual calendars viable replacements for all conventional calendars that are not written on.
