About The Gregorian Calendar

As there are so many calendars available in the world and people are following those according to their culture and tradition.

However, it would not be wrong to say that the Gregorian calendar is the most famous and used among all. 

The Gregorian calendar was introduced by Pope Gregory XIII in the year 1582.

In the early era of the Gregorian calendar, people found it more reliable and ideal than the previous calendars.

Now, it has become the international standard for representing dates and times.

Although most countries are using this calendar, still there are things that people may not know about the Gregorian calendar.

History Of The Gregorian Calendar

The Gregorian calendar replaced the Julian calendar because it had flaws and was inaccurate.

In 1582, Pope Gregory introduced the advance calendar known as the Gregorian calendar. It is the solar calendar that has 365 days in it which is divided into 12 months. 

7 of the months have 31 days and 4 have 30 days, while the 1 month has only 28 days during the common year.

However, after every 4 years, an additional day is added in February and then it becomes the month with 29 days. This particular event is known as a leap year with 366 days in total.

Who Designed The Gregorian Calendar?

There were innumerable changes to the calendar we use today.

We know that the Gregorian calendar was introduced by Pope Gregory XIII but it was designed by Luigi Lilio who is also known as Aloysius Lilius.

Luigi Lilio was born in Italy around 1510 and died in 1576. He later served his country as a doctor, astronomer, and philosopher.

Although he designed the calendar, he died six years before the Gregorian calendar was officially introduced.


Now, most of the countries are using the Gregorian calendar because it is far more accurate than the Previous calendar like Julian.

Those more advanced calculation formulas make it more reliable but it is also not perfect either. In every 3236 years, this calendar is off by one day.
