Calendar year[]A calendar year begins on the New Year's Day of the given calendar system and ends on New Year's Eve, and thus consists of a whole number of days. The astronomer's mean tropical year, which is averaged over equinoxes and solstices, is currently 365.24219 days. As this is not an integer, solar calendars have strategies to adjust for the 0.24219 remainder.

For example, it is the time from vernal equinox to the next vernal equinox, or from summer solstice to the next summer solstice. It is the type of year used by tropical solar calendars.
WeekA week (in the Western and international context) is a unit of time equal to seven days. It is the standard calendrical period between a day and a month in most parts of the world. There are just over 52 weeks in a year, or on average 4+1⁄3 weeks in a month. The days of the week are often used to set work days, rest days, and holy days. The term "week" is also used to refer to a sub-section of the week, such as the workweek and weekend.Intercalation (timekeeping)Look up or in Wiktionary, the free dictionary.
DayA day is the timeperiod of a full rotation of the Earth with respect to the Sun. On average, this is 24 hours (86,400 seconds). As a day passes at a given location it experiences morning, afternoon, evening, and night. This daily cycle drives circadian rhythms in many organisms, which are vital to many life processes. A collection of sequential days is organized into calendars as dates, almost always into weeks, months, and years.
