Introduction
Calendars are a way of dividing and measuring time into manageable pieces. Calendars start with small units building into larger units, days, months, years. Calendars are used to track the sun and moon's cycles.
Types of calendars
Over history there have been many different calendars used by different cultures as a way to track time and provide routine. Various calendars have been based on seasonal variations, tracking the sun and moon and other stars. Here is a list of the more well known calendars.
Gregorian - currently used.
Julian - used before the Gregorian calendar.
Jewish - linked to the sun and moon.
Muslim - follows the moon.

French Republican - used 1793-1805. Had 365 days divided into 12 months of 3 weeks, 10 days each with 5 holidays at the end.
Perpetual - a calendar that is valid for many years. You can use it to calculate any given day of the month for a year.
History
To get an overview of how calendars developed over time, check out the following websites.
Britannica School is one of the EPIC databases. EPIC is a collection of reliable databases covering lots of different topics. It’s put together especially for New Zealand school students and helps to answer questions like this.

Type the keyword 'calendar' into the search box.
Select the calendar article.
You can select the reading level at the top of the article.
Tips: Search words, or keywords, are the most important words in our question. Usually it’s better to leave out small words like ‘the’, ‘a’ and ‘of’ and just choose the main ones, e.g [calendar]. We can always change our keywords or add more if we need to.
Tips: To get to the EPIC resources you may need a password from your school librarian first. Or you can chat with one of our AnyQuestions librarians between 1 and 6pm Monday to Friday and they will help you online. Some EPIC databases may also be available through your public library.
