The Gregorian calendar is a solar calendar based on the Earth's orbit around the Sun, with months of fixed lengths. The lunar calendar is based on the cycles of the Moon and has months of varying lengths, making it around 11 days shorter than the Gregorian calendar year. This leads to differences in how dates are calculated and the timing of religious or cultural events.


Was the Gregorian calendar based on the moon?

Although the Gregorian calendar has "months", it is not in any way governed by the phases of the moon. It is strictly a solar calendar, so its emphasis is to remain in sync with the solstices and equinoxes, the characteristics of the Earth's orbit of the sun. Only lunar calendars, like the Muslim calendar, and lunisolar calendars, like the Jewish calendar, are based on the phases of the moon, with each month beginning at the time of the new moon.

What event marks the start of Gregorian calendar?

The calendar is intended to mark the number of years since the death of King Herod the Great. The Roman abbot Dionysus Exiguus devised the new Christian calendar in 533. He knew that it was impossible to say when Jesus was born, but he knew, or thought he knew, when Herod died. So, he chose to begin his Christian calendar on the year of Herod's death, and he based this on the reign of the Roman emperor Augustus. Unaware that Augustus only adopted that name four years after his reign began, going by his birth name of Octavius until then, Exiguus commenced his calendar just 4 years too late.
