Definition

A calendar year is the number of days between dates with the same designation in adjacent years.

As a year is not an integral number of days, it is necessarily an approximation to the actual year.


\(\ds \) \(\) \(\ds 1\) calendar year
\(\ds \) \(=\) \(\ds 12\) months usually, depending on the calendar used
\(\ds \) \(=\) \(\ds 365 \text{ or } 366\) days, usually, but it depends on the calendar used


Calendar

A calendar is a technique to keep track of the passing of time throughout the course of a year.

Its objective is to provide a more-or-less standard way of identifying the time of year by associating a name and number to each day in the year.
