(In the early 20th century, scholars found that this “base date” was August 11 or AugBC.) It grouped days into sets, or cycles, as follows: baktun (144,000 days), k’atun (7,200 days), tun (360 days), uinal or winal (20 days) and kin (one day). The Long Count system identified each day by counting forward from a fixed date in the distant past. For this job, a priest working in about 236 BC devised another system: a calendar that he called the Long Count. After each interval the calendar would reset itself like a clock.īecause the Calendar Round measured time in an endless loop, it was a poor way to fix events in an absolute chronology or in relationship to one another over a long period. Every 52 years counted as a single interval, or Calendar Round. Under this system, each day was assigned four pieces of identifying information: a day number and day name in the sacred calendar and a day number and month name in the secular calendar.
The first, known as the Calendar Round, was based on two overlapping annual cycles: a 260-day sacred year and a 365-day secular year. They also used astrological cycles to aid in planting and harvesting and developed two calendars that are as precise as those we use today.

Consequently, Mayan knowledge and understanding of celestial bodies was advanced for their time: For example, they knew how to predict solar eclipses. The Maya strongly believed in the influence of the cosmos on daily life. READ MORE: Why the Maya Abandoned Their Cities Mayan Astronomy and Calendar-Making As a result, there were three or four different ways to write almost every word in the Mayan language.
Each one represented a word or a syllable, and could be combined with the others in an almost infinite number of ways. They also figured out how to grow corn, beans, squash and cassava in sometimes-inhospitable places how to build elaborate cities without modern machinery how to communicate with one another using one of the world’s first written languages and how to measure time using not one but two complicated calendar systems.ĭid you know?

In total, 70 out of the top 100 test-takers overall were MIT students.Ĭongratulations to everyone who participated in this year's exam!Ī full list of the winners can be found on the Putnam website. MIT students also dominated the rest of the scoreboard: 9 of the next 11 (each awarded $1,000), 7 of the next 9 (each awarded $250), and 49 of the 75 honorable mention rankings. She is the sixth MIT student to receive this honor since the award began in 1992. Junior Binwei Yan, who finished in the top 15, received the Elizabeth Lowell Putnam Prize, which includes a $1,000 award. This is the MIT team's seventh first-place win in the past nine competitions. Teams are based on the three top scorers from each institution. The 2022 Putnam team, listed in alphabetical order, are Deng, Robitaille, and Zhu. Daniel has placed as a Fellow every year he has competed in the exam. Putnam Fellows are first years Papon Lapate and Luke Robitaille, sophomore Brian Liu, junior Mingyang Deng, and senior Daniel Zhu.
