Dusky Flint the Temporal

Dusky Flint, later given a cognomen "the Temporal" for his contribution to the world, was born in the village of Winternap to the earth ponies Winter Glade and Meteor Dusk. His mother was a farmer; father an astrologist. Smiliar in coloring (dark grey coat and metalic blue mane) to his father, he was named after him.

Flinterian Calendar
First few years studying history, he noticed how difficult it was to keep track of dates throughout the different eras and important events of nations. Each nation, of course, considered different events to be if importance. This led to each country having its own calendar, creating a great deal of confusion. Though there had been many attempts to unify the calendar systems into one, they had always failed. Nonetheless, Dusky Flint delved into the the different calendars and their histories, pinpointing events that were the most important in the history of the world, until eventually he established three of the most important. These events each eventually started a new era.

He also established a specific format of writing dates to prevent more confusion, eventually settling with Y;XXXX, where "Y" is number of an era and "X's" are the years.

Dusky Flint also reworked the entire structure of time division after tracking positions of Sun, Moon, and stars for two years.

Seeking help in the royal court of the two celestial princesses, he desired for his calendar to be established as the official one. Convincing the princesses, his calendar was soon pushed into all the schools of Equestria. Because of Equestria's rising status as a superpower, the calendar soon spread into the surrounding nations and beyond. In less than five decades, the Flinterian Calendar was considered the standart world-wide.
