My first presentation

The diffrence between solar and lunar calendar

What They Measure

• Solar calendars measure the Earth's relative position to the sun and are based on the cycles of the seasons. Like the 12-month calendar used by most of the world, these calendars typically chart the Earth as it makes a full rotation around the sun. Lunar calendars chart the various phases of the moon. They measure months and years by looking at the moon, although most lunar calendars are actually hybrid "lunisolar" calendars that take both celestial bodies into account.

1. How They Work

   • Solar calendars break the year up into various months and usually end the year after the Earth has made a full rotation around the sun. This takes 365 days, plus an occasional extra day to account for left-over time. In contrast, lunar calendars look at the phases of the moon as it waxes and wanes. Its position often does not match that of the solar calendar, although they often still have 12 months. This is because they often begin a month when a new moon appears and conclude it when it has completed a full cycle. A purely lunar calendar does this without taking solar cycles into account. Using a calendar converter will help you determine exact dates.

   Cultures

   • The cultures that use lunar and solar calendars are different. The Hijri is an Islamic calendar, one of the few purely lunar calendars, and is used for religious purposes such as charting times for fasting. The Chinese lunar calendar is another example, but it is typically used only for checking auspicious days for festivals. Most cultures use solar calendars such as the standard Gregorian calendar, also known as the Western calendar, to measure a year.

   Celebrations

   • Lunar and solar calendars often have very different celebrations for marking the beginning or end of the year. For example, the Lunar New Year is a festival time in China for feasting and parades. Similarly, most Jewish holidays are determined by the Hebrew calendar, another lunar calendar, and Rosh Hashanah is the Jewish New Year. It is a time of celebration and introspection. Under solar calendars, New Year's Eve festivals on December 31 mark the end of the old year and the coming of the next.
