This is the second of our Medium level Eleven Plus maths quizzes on Time. If you have played our previous quizzes then you will be familiar with solving Time problems by now. But how confident are you when it comes to longer periods, like decades, centuries and millennia? This quiz will put you to the test!

Some things to bear in mind:

- Leap years are years divisible by 4
- Leap years that end with 00 must also be divisible by 400
- Centuries begin in years ending with 01, not with 00

There is quite a lot more I could tell you, but I just don’t have enough space here. But that’s alright – play the quiz and I’m certain that you will learn many more useful tips to help you in your exams.

1.

The Battle of Hastings took place in 1066. Which century was it in?

The 11th century

The 10th century

The 9th century

The 12th century

Add '1' to hundreds place position and you'll get the correct century: the 11th century. Similarly, the 1900s were in the 20th century, and we are now in the 21st century. If you count the centuries from the birth of Christ (AD or CE (Common Era)), you'll see why the century is always 1 more than the number of hundreds

2.

How many leap years are there in a 'century'?

24

25

Either 24 or 25

It is impossible to say

There are 100 years in a century, and a leap-year every 4 years so you would expect there to be 25 leap years in a century. But, years ending with 00 must be divisible by 400 as well as by 4. So, some centuries have 24 leap years, and some have 25

3.

How many months are there in a century?

12,000

1,200

120

12

There are 12 months in a year and 100 years in a century, so we work this one out by multiplying 12 by 100: 12 x 100 = 1,200

4.

If today is August 25th, how many days is it until Christmas?

120

121

122

123

There are 4 months between August 25th ad December 25th (Christmas Day). Two of them (August and October) have 31 days and two (September and November) have 30 days: 31 + 31 + 30 + 30 = 122

5.

BC refers to dates before the birth of Christ. An alternative is BCE. What does BCE stand for?

Before Calculating Events

Before Christian Effect

Before Christmas Event

Before the Common Era

AD (Anno Domini – the Year of Our Lord) refers to dates after the birth of Christ and CE (Common Era) is an alternative. The changes were made because billions of people use the calendar, but less than a third of them are Christians

6.

Queen Victoria’s rule began in 1837 and lasted for 64 years before her death. In which century did she die?

The 17th century

The 18th century

The 19th century

The 20th century

1837 + 64 = 1901. Remember: to find the century add 1 to the hundreds. 19 + 1 = 20.

Also remember, the century begins in years ending 01, not 00 so the 20th century began on January 1st, 1901

Also remember, the century begins in years ending 01, not 00 so the 20th century began on January 1st, 1901

7.

How many decades are there in a millennium?

10

100

1,000

10,000

A decade is ten years and a millennium is 1,000 years so to work this one out we divide 1,000 by 10: 1,000 ÷ 10 = 100

8.

Lucy’s baby is 35 days old. If today is October 22nd, what day was the baby born?

September 16th

September 17th

September 18th

September 19th

22 – 35 = -13. To find the baby’s birthday we must remove 13 days from September. September has 30 days so 30 – 13 = 17. The baby was born on September 17th

9.

Julius Caesar died aged 55 in 44 BCE, but before his birthday that year. What year was he born?

100 BCE

99 BCE

98 BCE

97 BCE

44 + 55 = 99 BCE. However, Julius died before his birthday that year. If he had lived, he would have been 56 after his birthday. 56 + 44 = 100 BCE

10.

Which of the following will not be a 'leap year'?

2092

2096

2100

2104

Leap years usually occur if the year is divisible by 4. However, in the case of centuries (1800, 1900, 2000, 2100 etc) the year must also be divisible by 400
