Number of days in a year; How many days are there in a year?

## How many days in a year

### Year

A year is 365 days long. There are about 33,557,600 seconds in a year. However, not everyone has the same number of seconds in a year. For example, an hour is 60 seconds, a day is 24 hours, and a week is 7 days.

In the Gregorian Calendar, a common year has 365 days. Every four years there is a leap year, where the month of February has one extra day, and thus on a Leap Year, there are 366 days. (Source: www.calendarr.com)

### Gregorian

How many days in a year? Depending on when you ask the question, you could get a confusing answer.

A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars (see below). For the Gregorian calendar, the average length of the calendar year (the mean year) across the complete leap cycle of 400 years is 365.2425 days. In English, the abbreviations "y" and "yr" are commonly used ("a" is also used) for the unit of time, though its exact duration may be inconsistent. (Source: en.wikipedia.org)

### Leap Year

One of the first and most obvious questions that is often asked is "How many days in a year"? This question is often asked because of the two ways to determine the answer. First, the answer that deals with the calculations of the length of the year is the Gregorian calendar. This calendar is named after Pope Gregory XIII, the Pope that introduced a new calendar in 1582.

The lunar year comprises twelve full cycles of the phases of the Moon, as seen from Earth. It has a duration of approximately 354.37 days. Muslims use this for celebrating their Eids and for marking the start of the fasting month of Ramadan. A Muslim calendar year is based on the lunar cycle. The Jewish calendar is also essentially lunar, except that an intercalary lunar month is added once every two or three years, in order to keep the calendar synchronized with the solar cycle as well. Thus, a lunar year on the Jewish (Hebrew) calendar consists of either twelve or thirteen lunar months. (Source: en.wikipedia.org)
