The Calendars that Confuse us
Though the calendar year universally commences on 1st January and ends on 31st December, various nationalities throughout the globe follow different reckonings distinct from this standard frame of 1st January to 31st December.
What is currently followed globally is the Christian calendar beginning from the Birth of Christ.
This era is separated as BC (Before Christ) and AD (Anno Domini).and we are today in the year 2007 AD.
From ancient times, it is the Sun that has been the base on which time and seasons were counted upon. The Sun was God to the primitive races that inhabited planet earth.
The ancient Egyptians adored it while the Romans called the Sun God “Ra”.
In fact there was festivity when the sun rose to its heights, and a festival titled “Saturnalia” in honour of the Sun God was kept.
In fact it was this festival that later came to be celebrated as Christmas by the 3rd century Christian community in Rome.
Though the current 12 months are solar months, what prevailed earlier in most countries was Lunar months and all dating was based on the Lunar calendar system.
But from the beginning, time has been measured astronomically according to the revolutions of the sun and moon and to the recurring celestial phenomena. As distinct from the Christian era, we also have now the Buddhist era, Hindu era etc. The Chinese for example have there own New Year not taking the January – December cycle into reckoning.
Just as the Christians count their era from the birth of Jesus, the Buddhists do from the demise of Lord Buddha in 543 BC.
The Hindus begin from the Saka era which is the date of the coronation of King Kanishka in India in AD 78.
Meanwhile the Muslims count from the flight (Hijra) of the prophet from Mecca to Medina in AD 622, which is called the Mohammedan era.
The ancient world counted the years from the date of creation in 5508 BC and calls it the Constantinople era.
The Romans counted it from the founding of Rome in 753 BC. The first era made use of by the Greeks was that of the Olympias. All these boiled down to the new Christian era in 394 AD.
