1. There is a confusion in the categories regarding settlements and a consensus should be reached on when or if the categories should be "settled in" or "established in" or "settlements established in" etc. I am willing to accept any solution but if there are no guidelines, then the categories used will be inconsistent. At present many categories are used at the same time.
2. There is a second issue, which needs corrections. In defining the decades in various programs a decade starts with the year 0 and finished with the year 9. This is basically incorrect.
A century starts with the year 1 and ends with the year 100. Thus the 10th century starts with the year 901 and ends with the year 1000 (an not from year 900 to year 999. Similarly a millennium starts with the year 1 and end with the year 1000. Thus the first millennium starts with the year 1 and ends with the year 1000 and the second millennium starts with the year 1001 and end with the year 2000. Why would decades be otherwise defined. The system used at present presents 1000 as the first year of the 11th century, which moves it to the 2nd millennium.
Therefore templates such as estcat are to say the least controversial. I have developed templates such as estcat1 in which decades start with the year 1 but using both leads to inconsistent results. Afil 01:27, June 27, 2011 (UTC)
