There are 100 years in a century. While a century can technically describe any period of 100 years, it's typically defined as starting with a year that ends in one and ending in a year that ends in 00 or 100. For example, the 20th century began in 1901 and ended in 2000. The 21st century began in 2001 and volition finish in 2100. This measurement of time is based on the Gregorian calendar or New Fashion Agenda that most of the world uses today.
Decades
Each century is made up of ten decades, a series of 10 years. Similar centuries, decades can embrace any period of 10 years. Just when referencing the Gregorian agenda, a decade begins in a year that ends with ane and ends with a year that ends in 0. For example, the 1990s officially began in 1991 and ended in 2000. Yet, it'south more common for people to start and terminate a year before. In this case, the 1990s began in 1990 and ended in 1999.
Y ears
Both centuries and decades are made up of years. A yr is a flow of 12 months that begins on January 1 and ends on Dec 31. Each year is also fabricated upwardly of about 365.25 days. However, most people consider a twelvemonth to last only 365 days. So, every four years, those 4 extra quarters come together to create a year that lasts 366 days. This is called a leap year. A twelvemonth is also the catamenia of time that it takes for the Earth to circumduct around the sunday.
Grand onths
Each year is divided into 12 months. Some months — January, March, May, July, August, October and Dec — are made up of 31 days. April, June, September and Nov are made upwards of 30 days. February is typically made up of 28 days, but during a spring twelvemonth, it has an actress 29th 24-hour interval. The timing of the months was based on the moon's orbit.
D ays and Weeks
Days are periods of roughly 24 hours that start at midnight and stop at 11:59 p.thousand. every night. Each twenty-four hours covers the time period it takes for the Globe to rotate on its axis. In that location are seven days in a calendar week: Monday, Tuesday, Wed, Thursday, Fri, Saturday and Sunday. Saturday and Lord's day are the weekend, while Monday through Fri are weekdays. There are 52 weeks in a twelvemonth.
S easons
Another fashion to measure time is past counting the four seasons: jump, summertime, fall and winter. Seasons change based on the mode the World tilts on its centrality as it revolves effectually the lord's day. Each season lasts for about three months. Spring begins in March at the fourth dimension of the spring equinox. Summer begins in June at the fourth dimension of the summer solstice. Fall begins in September at the time of the fall equinox. Wintertime begins in December at the fourth dimension of the winter solstice.
T he Gregorian Calendar
Most of today's measurements of time are based on the Gregorian calendar, which was made official by Pope Gregory Thirteen in 1582. It took the place of the Julian agenda, which was found to be slightly inaccurate. Italy, Poland, Portugal and Kingdom of spain were the outset countries to utilize it. Many Protestant countries hesitated to use it because they felt information technology was a ploy by Catholics to suppress their views. In 1752, England and the colonies that went on to form the The states adopted it. It remains the most widely-used calendar.
