Year46 BC was the last year of thepre-Julian Roman calendar. At the time, it was known as theYear of the Consulship of Caesar and Lepidus (or, less frequently,year 708Ab urbe condita). The denomination 46 BC for this year has been used since the early medieval period, when theAnno Dominicalendar era became the prevalent method in Europe for naming years.
This year marks the change from the pre-Julian Roman calendar to theJulian calendar. The Romans had to periodically add a leap month every few years to keep the calendar year in sync with thesolar year but had missed a few with the chaos of thecivil wars of the late republic.Julius Caesar addedMercedonius (23 days) and two otherintercalary months (33 and 34 days respectively) to the 355-daylunar year, to recalibrate the calendar in preparation for his calendar reform, which went into effect in45 BC.[1][2][3] The resultingcalendar year, the longest calendar year in recorded history, lasted 445 days — nearly 80 days longer than thesidereal year (the orbit of Earth around the Sun) — and was nicknamed theannus confusionis ("Year of Confusion").[4]

November – Caesar leaves forHispania to deal with a fresh outbreak of resistance.
Caesar reforms theRoman calendar to create theJulian calendar. The transitional year is extended to 445 days to synchronize the new calendar and the seasonal cycle. TheJulian Calendar would remain the standard in thewestern world for over 1600 years, until superseded by theGregorian Calendar in 1582.
