[edit] Notes on years

Year 1950 of course means 1950 CE, but negative years can be interpreted in two different ways. The mathematically most meaningful interpretation is to let 0 represent year 1 BCE, and year -1000 represent 1001 BCE. A more straightforward interpretation is to let -1000 mean 1000 BCE, but then year 0 means nothing at all. In the table below, either interpretation may be used - the slight difference is irrelevant for our purposes here. Similarly, -1,000,000 may mean 1,000,000 BCE, 1,000,001 BCE, or 1,000,000 BP, i.e. about 998,000 BCE (writing around year 2000).
