How to Write Dates in Standard American English

The correct way to write dates in Standard American English follows a specific set of rules. Following these rules ensures clarity, consistency, and adherence to the conventions of American English. This article will provide a comprehensive guide to writing dates accurately and stylistically.

Basic Date Format

The basic American English date format consists of three parts:

  • Month: Written as a full word or abbreviated to three letters (e.g., March or Mar)
  • Day: Written as a numeral (e.g., 15)
  • Year: Written as a four-digit number (e.g., 2023)

The three parts are separated by commas or spaces. For example:

  • March 15, 2023
  • Mar 15, 2023

Commas vs. Spaces

The use of commas or spaces to separate date elements depends on the context.

  • Commas: Use commas when the date appears in a sentence as a complete phrase.
The meeting will be held on Wednesday, March 15, 2023.
  • Spaces: Use spaces when the date appears in a table, list, or other non-sentence context.
| Date       | Event   |
| ----------- | -------- |
| Mar 15, 2023 | Meeting  |

Ordinal Numbers

Ordinal numbers (e.g., first, second, third) are used to indicate specific days of the month. They are written as superscripts and follow the day numeral.

The first day of spring is March 20th.

Months with 31 Days

Months with 31 days (January, March, May, July, August, October, December) can be abbreviated to two letters.

Months with 30 Days

Months with 30 days (April, June, September, November) are not typically abbreviated in Standard American English.

February

February is always written in full or as "Feb". The use of "Feb." is preferred when space is limited.

Centuries

Centuries are written as four-digit numbers. Do not use the abbreviation "c." or "C.E." with centuries.

The 21st century began in 2001.

Historical Dates

When writing historical dates that occurred before 1000 AD, use the format "BCE" (Before the Common Era) or "BC" (Before Christ).

The Roman Empire fell in 476 BCE.

Writing Dates with Time

When including time with a date, use a colon to separate the two.

The flight departs at 11:30 AM on March 15, 2023.

Capitalization

The month and day are not capitalized in Standard American English. However, the year can be capitalized when it appears as the first word of a sentence.
