The coloured days highlight
other historical milestones, and recurring events such as anniversaries and
icons indicate the phases of the moon and appear only for dates in the Gregorian calendar, i.e. after 14 October 1582. The Chinese calendar is available only from 1645 to 2644, the first millenium since the last reform. The coloured columns mark the Sundays, the last day of the week per standard ISO-8601.
The normal calendar page for the current /year?2018 contains an introduction to the intriguing history of the year as we know it. The Calendar Converter has more detail. The so called Perpetual Calendar uses a trick from before the age of computers to find the weekday for any Gregorian date. Also see an overview of all historical events in the last six thousand years.
