Most historians will go with the fall of Rome in 476 as the beginning of the medieval period. There are problems with this, not the least of which was that the Roman Empire did not fall at that time, but it is as good a date to use as any, and they usually know what you mean when you use 476.
The "fall of Rome" of 476 happened at a time when the empire was divided into two halves. The Emperor of the West was deposed, and the Roman Senate sent a delegation to the Emperor of the East, asking that he take charge of the whole thing again, which he did, in theory. The western parts of the empire were overrun by Germanic tribes that set up their own kingdoms, and while most claimed to be in the empire, they never supported the empire in any way. The East Roman Empire, which modern historians have taken to calling the Byzantine Empire, lasted until 1453, a date commonly taken as the end of the Middle Ages. There are links below.

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.
A mass extinction event/ice age marked the end of the Ordivician Period. The climate, location of landmasses, and number and diversity of species had changed dramatically since the beginning of the period. When the changes that were occurring during the mass extinction event leveled out, a new period began.
The Battle Of Hastings
The end of the Silurian period and the beginning of the Devonian period was not defined by an extinction event, but by the distinctive rock formations of the period. As a result the end of the Silurian period is uncertain by +/- 2.8 million years.
The Storming of Bastille
The frequency of the event over that time period.
