Presenting 1440

The year 1440 was a leap year starting on a Friday, just like 1356, 1384 and 1412 in the century before it and 1468, 1496 and 1524 in the next.

The coloured days highlight birthscake, deathsdagger, politicalcrown, scientificpaperclip, artisticpaperclip and otherasterisk historical milestones, and recurring events such as anniversaries and holidaysanchor. The newnew moon, waxingwaxing moon, fullfull moon and waningwaning moon 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.

Calculating time

The normal calendar page for the current /year?2017 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.
