The Julian calendar
46 BC · Rome
In short
The old Roman calendar was several weeks out of step with the seasons. Julius Caesar asked the astronomer Sosigenes of Alexandria for help and created a year of 365 days, with an extra day every four years. To put things right, 46 BC lasted no fewer than 445 days and was called ‘the year of confusion’. The new calendar came into force on 1 January of the following year.
Why it matters The calendar we use today is a correction of the Julian one, decided in 1582.
