To work out centuries you do the same… • Take the first 2 digits of a date

eg: 1945 (1st 2 digits are 19)• ADD 1 : (So 19 + 1 is 20)•So 19451945 is in the 2020thth Century Century

In a date with only 3 3 digitsdigits

eg: 945 AD •Use the first digit (eg 9)•ADD 1 : (So 9 + 1 is 10)•So 945 AD945 AD is in the 1010thth CenturyCentury

1321 is in the 1321 is in the 14th 14th centurycentury

13211321

1313 + 1+ 1 = 14= 14

So 1321 is in the 14So 1321 is in the 14thth Century Century

800 is in the 800 is in the 9th 9th centurycentury

800800

88 + 1+ 1 = 9= 9

So 800AD is in the 9So 800AD is in the 9thth Century Century
