Calendar

A system of organizing days for a social, religious, commercial or administrative purpose.
This organization is done by giving names to periods of time typically days, week, monthes and years. The name given to each day is known as date.

Periods in a calender are usually, though not necessarily, syncrronized with the cycles of some astronomical phenomenon, such as the cycle of the sun, or the moon.

Many civilizations and societies have devised a calendar, usually derived from other calenders, on which they model their systems, suited to their particular needs.

A calendar is also a physical device. This is the most common usage of the word. Other similar types of calendars can include computerized systems, which can be set to remind the user of upcoming events and appointments.

The English word "calendar" is derived from the Latin word "Kalendae", which was the Latin name of the first day of every month.

The primary practical use of a calendar is to identify days - to be informed about and/or to agree on a future event and to record an event that has happened.

Calendars are also used to help people manage their personal schedules, time and activities, particularly when individuals have numerous wrok, school, and family commitments. People frequently use multiple systems, and may keep both a business and family calendar to help prevent them from over committing their time.

Calendars are also used as part of a complete timkeeping system: date and time of day together specify a moment in time. In the modern world, written calendars are no longer an essential part of such systems, as the advent of accurate clocks had made it possible to record time independently of astronomical events.

Keep track of all the events in your life, coordinate schedules with friends and family and find new things to do.
