In ancient times, every Christian church had its own calendar and its own method for calculating Easter. And therefore, the time of celebration of the brightest holiday for all Christians, the Great Christ’s Resurrection, varied in time depending on the accuracy of the calculation of the calendar.
How to calculate the date of Easter
And only at the First Ecumenical Council in 325 they decided that Easter should be celebrated by all Christians in one day and instructed the Alexandrian church to calculate Easter.
The calculation rules were established to celebrate Easter:
Easter should be on the first Sunday after the first full moon, which will come after the spring equinox;
The holiday should be after the Old Testament Easter.
The method of calculating Easter was very complicated, several cycles were taken as a basis, which were considered from the day the world was created (“Summer from Adam”). To find out what kind of “summer is from Adam” now, by the year of our era, you need to add number 5508. In 2014, we have 7522 years from creating the world. The next cycle that was needed to coordinate Easter is an indicator. Indicts are only 15. To calculate which indict is now, you need to divide the year from the creation of the world into 15 without fractional numbers. The remainder that turned out is the indict. That is, 7522 = 501*15+7. So 2014 is a year 7 indication.
The necessary cycles of the calculation of Easter were the “Circle of the Sun” and “Circle of the Moon”.
Sunny (28 years) and lunar (19 years) cycles are based on.
Everything is calculated by the previous method: 7522 = 268*28+18 (18 circle to the sun)
Next, we calculate the lunar cycle: 7522 = 395*19+17 (17 Circle of the Moon)
Therefore, if the laws of the Middle Ages reigned now, then the date of birth 05.03.2014 would look like this: “During the reign (the name of the ruler of the country in which a man was born) on a bright week on Wednesday, the servant of God (the name of man) of Indict 7 was born, and the moon is 17, and the sun is circle 18”
It is interesting that the coincidence of the “circle of the Sun” and the “circle of the Moon” took place 1 time in 532 and was called the “Great Indict”, and the coincidence of the indication and two “circles” never occurred. It was a very accurate calendar of periods. The last great indict from the Summer of Adam was in 1941.
Further, on the basis of ancient church tables, the date of Easter was calculated
How to calculate the date of Easter
Easter was celebrated by Catholics and Orthodox on one day until 1583. Then the Roman Catholic Church switched to the Gregorian Easter, it was considered more precisely astronomically and the second point was removed from the rules. Then the Easter calendar has completely changed, and the Catholic Easter can now coincide with the Easter of the Jew. Due to the fact that the difference between the Julian and Gregorian solar calendar is 13 days and when calculating, different methods of calculating full moon are used, now Catholic and Orthodox Easter differ in the date of celebration sometimes for almost a month.
How to calculate the date of Easter
Catholic Easter coincides with the astronomical date, since the Gregorian calendar is more precisely of the ancient Julian, according to which the Orthodox Church now lives. But in defense of their faith, the Orthodox leads to the fact that it is in the date of Orthodox Easter that the Lord is one of the greatest miracles – the convergence of a blessed fire in Jerusalem.
How to calculate the date of Easter
The convergence of the fertile fire occurs on the eve of the great Saturday on the prayer of only the Orthodox Patriarch in the temple of the Holy Sepulcher. The fire has wonderful properties, at the beginning of his fire he does not burn at all. People have 33 candles in their hands (by the number of years of Christ) and lighting candles with fertile fire, they can draw a burning pile through their hair and beards, without ignition. Only after a while does the fire acquires its usual properties. The removal of the wonderful light symbolizes the great miracle of the resurrection of Jesus Christ.
