A century is 100 years, so one quarter of a century is twenty-five years.
Ten years is a decade. Twenty years is a score.
The 20th century. We add 1 to the first two digits to get the century. This is since the first century is classed as the years 0 to 999, the 2nd century the years 1000 to 1999 etc.
A century is a period of 100 years. A decade is 10 years.* Historical periods are often defined as a century. However, because there was no 0th century, the century number is always 1 higher than the first two digits of the year number (e.g. 1950 is in the 20th century) except for years ending in 00, which are in the preceding century (1900 is in the 19th century with 1801-1899).
The years 0-99 are referred to as the 1st century. The 1900's were referred to as the 20th century and therefore the year 2000 was referred to as the twenty first century. Sorry if this explanation doesn't make much sense or doesn't answer your question correctly.
