What century was the year 1978?
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.
What will be the year 1 century from today?
A century has 100 years, so just add 100 to the current year.
How do you find the sum of digits of each number?
Add the digits together. The sum of the digits of 23 is 5.
What century was the year 1451 in?
The year 1451 was in the 15th century.Remember it this way. The year 1451 is CCYY where CC = Century and YY = year.To get the century always add 1 to CC. Why? Well, that's because the counting started at zero. Therefore, the first day of the first year of the first century was the 1st century (and not the zero century). The first day of the first year of the second cenrury was the 2nd century and so on.
