# Basic Math/Century Year Numerical Digit.

Question
Dear Prof Pawan

http://en.wikipedia.org/wiki/Century
http://en.wikipedia.org/wiki/21st_century
http://en.wikipedia.org/wiki/3rd_millennium

1 Century = 100 years.
100 Centuries  = 100 * 100 years = 10 raised to power of 4 = 10000 years.

20th century = 1901 to 2000
21st century = 2001 to 2100 -> Currently we are in this century.
22nd century = 2101 to 2200
23rd century = 2201 to 2300
.
.
.
.
98th century = 9701 to 9800
99th century = 9801 to 9900
100th century = 9901 to 10000
101st century = 10001 to 10100
.
.
.

Year becomes a 5 digit number.

1.

1 century = 100 years. Mathematically 100 centuries = 10000 years,
Is there be any other term for 100 centuries similar to 100 years
termed as a century ?.

2. Does last year of 100th century and 101st century 100 years becomes a 5 digit numeric year figure as shown above ?.

3. Can there be any other term used instead of
"We are in 100th century" ?. in 100th century as we say currently "We are in 21st century" and currently the year is 2013 ?.

Thanks & Regards,
Prashant S Akerkar

Prashant,
Here are my thoughts on your questions:

1. I am not aware of any term for 100 centuries.
century = 100 years
millennium = 1,000 years
http://en.wikipedia.org/wiki/Time#Measurement

http://www.vpcalendar.net/Definitions/Time_Measurements.html

2. You are right

3. As there is no specific unit for 100 centuries, '100th century' will be the right term.

I hope that this helps.
All the best!

Regards,
Pawan
