## How to convert years from numbers written in numerals to American and British English words, written with letters?

### Below we talk only about years between 1 and 9999.

• There is no year zero, neither AD (CE) nor BC (BCE). Read bellow about these acronyms.

### Below there is a set of steps to follow in order to convert number years to words...

• 1. For years of four digits (ie: 1000, 1435, 2000, 2018, ...9999)
• 2. For years of three digits (ie: 100, 137, 209, 357, ...999)
• 3. For years of one or two digits (ie: 1, 5, 10, 45, 137, 209, 357, ...999)
• 4. AD, BC, CE, BCE acronyms

### 1. For years of four digits (ie: 1000, 1435, 2000, 2018, ...9999)

#### 1.1. For years ending with three zeros there is only one way of writing them out:

• 1000 = the year one thousand, in both American and British English words;

• 2100 = the year twenty-one hundred, in both American and British English words;

#### 1.3. If only the second and the third digit (hundreds and tens digits) are zeros, there are three ways of writing out the year:

• 1005 = the year ten oh five, in both American and British English words;
• 1005 = the year one thousand five, in American English;
• 1005 = the year one thousand and five, in British English;

• 2010 = the year two thousand ten, in American English;
• 2010 = the year two thousand and ten, in British English;
• 2018 = the year twenty eighteen, in both American and British English words;
• 2018 = the year two thousand eighteen, in American English;
• 2018 = the year two thousand and eighteen, in British English;

#### 1.5. If the third digit (tens digit) is zero, then there are two ways of writing out the year:

### 3. For years of one or two digits (ie: 1, 5, 10, 45, ...99)

#### 3.1. Simply write the number out. There is only one way of writing out the year:

• 1 = the year one, in both American and British English words;

• 10 = the year ten, in both American and British English words;
• 13 = the year thirteen, in both American and British English words;
• 45 = the year forty-five, in both American and British English words;

### 4. AD, BC, CE, BCE acronyms

#### You can place AD (or CE) before or after the year // OR // BC (BCE) after the year.

• AD = Anno Domini (Latin phrase for "in the year of the Lord").
• 1 AD (or AD 1 in a stricter notation) is considered the year in which Jesus Christ was born.
• Example: the current year, 2024, is: 2024 AD.
• BC = Before Christ; years before 1 AD.
• There is no year zero, neither AD nor BC.
• Nowadays CE and BCE acronyms are also used.
• CE = Common Era, instead of AD.
• The year 1 CE = The year AD 1 (or 1 AD).
• BCE = Before the Common Era, instead of BC.

#### Examples:

• The year 1966 after the year 1 AD: AD 1966 = the year nineteen sixty-six AD (Anno Domini);
• The year 1250 before the year 1 AD: 1250 BC = the year twelve fifty BC (Before Christ);
• The year 1966 after the year 1 CE: 1966 CE = the year nineteen sixty-six CE (Common Era) = the year nineteen sixty-six AD;
• The year 1250 before the year 1 CE: 1250 BCE = the year twelve fifty BCE (Before the Common Era) = the year twelve fifty BC;
