How to correctly determine the century by the year: the table of the relationship between centuries by year

From days, a month consists, from the months of the year, from years - centuries. You will learn about how to consider and translate years in the centuries from the article.

History is counted sometimes with minutes, and most often for centuries. The last units of dimensions are especially significant for her, because the events and dates that we call eras are included in them. How not to “get lost in time” and correctly determine the period of the story that is discussed?

How are centuries, centuries in history?

• A year, as well as the century, is the most used concepts used for temporary determination of historical events. Less commonly, temporary frames indicated by millennia are used. And if in the year we count 365 days (or 366 - in a leap), “measuring” it also with seasons: from spring to autumn, from summer to winter, then the years are formed in decades, and then in centuries, which we have called centuries.
• The beginning of the century is the year in which the last two digits are 01. Two zeros at the end determine the final year of the century. So, 1801 is the start of the 19th century, and 1900 is its end. The next, 1901, the year is already starting the 20th century counting.
• In most countries, a countdown was adopted years and centuries "from the Nativity of Christ." It was the first year from this event that is the beginning of our era.

• Today in the yard of the 21st century, therefore, 20 centuries have passed from the Nativity of Christ, and now it lasts the 21st. But everything that preceded this date is customary to determine the term “before our era”.
• Here the account goes as if in the reverse order: for example, the fourth follows the 5th year. And if we want to know how many years ago a particular event happened before our era, you just need to add the number of the year in which the event of interest to us happened by the current year. So, for example, from 2019 to 184 BC 2203 passed (2019+184).
• It is also not difficult to learn the ratio of centuries and years, remembering that in the century - a hundred years. We divide by 2203 by 100 and get 22 full centuries.

What is the ratio between the century and the year?

• If we know in what year this or that event occurred, then determining the corresponding century is quite simple.
• Just enough divide a year into 100, and then the resulting part of the private increase by one. For example, we need to find out what century the 1243rd year belongs. Divide 1243 by 100 and we get 12.43. The whole part is 12. Add to it 1 and we get 13. Thus, we received that the 1243rd year is the 13th century.
• If division by one hundred It occurs without tenth parts, then we leave the whole part unchanged. So, the 2000th year is the 20th century, since 2000 will be divided into 100 turns out 20.

• Another method is lighter the ratio of centuries over the years - Do not share anything, but simply add a unit to the first first numbers. The same rule applies to determine the centuries BC. So, the 672nd year BC It is the 7th century (of course, also BC). Why? Because, having discarded the last two numbers, we will receive 6, and adding a unit to it - 7.
• By the way, in the same way it is possible to determine not only the century, but also a millennium, with one correction: not two, but only one first digit remains from year. Example: flight into space Yuri Gagarin occurred in 1961.
• We leave the first digit 1 and add another one to it. We get 2, i.e. This happened in the second millennium. And also we do not add anything to the first figure if zeros follow it.

The ratio of centuries and years: table

In this table the ratio of centuries over the years The first digit is a century, and the next two years - years starting and completing this century.

A similar table can be compiled for the ratio of years from centuries BC. She will look the same, with the difference that the first and last years will change places.
