there has to be a reason why someone chose those odd dates. Climate scientists tend to use nice round numbers like 1800 or 1900.”

That seams to be rather odd advice. Most datasets don't start no nice round numbers. Typically when scientists choose a dataset, they don't pick an arbitrary round number. They pick the start of the data set. So if you see 1979, it's probably because that's when the satellite record started. If you see 1958 for CO2 it's probably because that's when the CO2 record at Mauna Loa started.

Central England during odd ranges of dates, like 1663-1762.

sounds like the start of the CET temperature record for a 100 year period. It started in 1659, but maybe the first few years were bad data, or they wanted a 5 year running average.
