Why the the calendar are two types?

Question

Gregorian & Arabic calindar

Answer 1

because one is lunar and other is solary

Answer 2

There were several calendars through out history. Only a few survive today. The Gregorian calendar happened when Pope Gregory tore off 10 days to adjust it to what is considered a solar year. This calendar came based from the Julian calendar of the Roman Empire. Julius Caesar's invention. Great Britain and her colonies still kept the Julian calendar until the 1750s. That is why sometimes you see 2 different dates of birth or death for people born in this country before the adoption of the Gregorian calendar. Even with the Julian and Gregorian calendars, the Jews still kept their calendar. It is based on their religion. The Muslim calendar is based on the ideas of Muhammad. It traces it back to when Islam was founded and like the Jewish and Chinese calendars is a lunar calendar. So, I guess the big difference between the calendars is the Gregorian calendar is solar which is more accurate and the others are lunar which is not as accurate; hence the different times of year their holy days are in different seasons from time to time.

Answer 3

There are several more: Druidic, Mayan, Jewish, Orthodox. Back before we could communicate instantaneously, and when local communities organized their festivals around the phases of the moon and stars, practically every culture had its own calendar. Now that the entire world does business with each other and needs to be able to agree on when and where to exchange goods, services and information, we don't use all the ancient calendars any longer. The reason almost everyone uses a modified Gregorian calendar (sometimes the Orthodox, sometimes the Arabic) is that Western Europe dominated trade and diplomacy for most of the 17th - 20th centuries, so they got to impose their version of reality on everyone else in the world.

Answer 4

The Arabic calendar is based on the teachings of Mohammad, and follows a pattern decided by the followers of Islam.

The Gregorian calendar was an attempt to organize the year into a predictable pattern, and was based on earlier calendars of the Roman Empire.

There are all kinds of calendars because people have needed to know when to plant things, or when to be careful for different kinds of bad weather, or when to celebrate someone's important anniversary - birthday, becoming the king, wedding, winning a war.

Answer 5

The Gregorian calendar was invented by Pope Gregory. The Arabic calendar has been in existence for for longer. It depends in you culture what calendar you use.

Answer 6

The Chinese have their own calendar. There is also the Jewish calendar. The other calendars were begun when the culture began. So if the culture is older, so is the year on the calendar.
