What are the differences between Eastern Orthodox Church and Catholic Church ?

Catholics 1.2 Billion. One leader. 17 million new converts last year.

Orthodox. 578 million. No leader. Co-opted by the Communists.

Different Calender.
Easter Orhodox maintain to use the old calender, like it's Christmas is like 10 days after the Western Christmas.

There are some tiny variance in the Holy Bible and it's name for each "chapter".
Different clot hings for nuns and Fathers, Mothers, Brothers and Sisters.

Genneral the same beliefs

You mean, the differences between the Eastern Orthodox church and the Roman Catholic church; one is based in Constantinople (Eastern) and one is based in Rome (Roman).

Outside of that: the EOC has no pope. The RCC has a pope. There are other minute theological differences too: the EOC believes that the Holy Spirit proceeds from God the Father only, and the RCC believes the Holy Spirit proceeds from the Father and the Son.

A lot of ceremony, heavy facial hair, and the non-acceptance of the Pope as the head of the Christian church. The schism occurred when Rome and Constantinople disagreed about who was to head the church, the Pope in Rome or the Emperor in Constantinople.

The Eastern Orthodox Church uses the original Nicene Creed.
The Roman Catholic Church uses a tampered Creed with the addition of the Filioque.

The Holy Orthodox Catholic and Apostolic Church and the Roman Catholic Church were one Church - the Catholic Church - for over 1,000 years. Common to both are most of the points of the Nicene Creed (http://www.goarch.org/chapel/liturgical_texts/creed).
* belief in the Holy Trinity - Father, Son and Holy Spirit
* the crucifixion and resurrection of Christ
* the future return of Christ and his everlasting kingdom

Similar also are
* liturgical worship
* the seven major sacraments (Orthodoxy recognizes more)
* the change of communion bread and wine into the body and blood of our Lord Jesus Christ
* baptism in the name of the Father, Son, and Holy Spirit
* male clergy consisting of bishops, priests, and deacons

The chief differences which caused the split between Orthodox Christianity and Roman Catholicism:

Orthodoxy believes
* the Holy Spirit proceeds from the Father (Nicene Creed and John 15:26)
* Christian unity derives from Christ and all the apostles, with no ruling bishop over all.

Roman Catholicism believes
* the Holy Spirit proceeds from the Father "and the Son" (a Roman addition to the Creed)
* Christian unity derives from the Pope of Rome
Later dogmas that are required for Roman Catholics to believe, but are not Orthodox dogmas:
* purgatory
* infallibility of the Pope
* the immaculate conception of Mary
