Definition of calendar year. 1 : a period of a year beginning and ending with the dates that are conventionally accepted as marking the beginning and end of a numbered year. 2 : a period of time equal in length to that of the year in the calendar conventionally in use.
A calendar day is a 24 hour period between two consecutive midnights. During a day, we experience both day time as well as night time. Day time, which is literally referred to as day, is the part of the day when the Sun is up in the sky. In other words, a day starts with the sun rise and ends with the sun set.
