Days, Months, Dates in English

Overview

Knowing the days of the week, months of the year, and how to say and write dates is fundamental at the A1 (Beginner) level. You need this vocabulary for making plans, talking about schedules, discussing birthdays, and understanding calendars.

One important rule in English is that days and months are always capitalized. Unlike many other languages, this is a strict rule in English writing, and forgetting it is a noticeable error.

English has two main date formats -- British and American -- which can cause confusion. Learning both will help you avoid misunderstandings, especially with numerical dates.

How It Works

Days of the week

Day	Abbreviation
Monday	Mon
Tuesday	Tue / Tues
Wednesday	Wed
Thursday	Thu / Thurs
Friday	Fri
Saturday	Sat
Sunday	Sun

The week starts on Monday in most English-speaking countries, but calendars in the United States often start on Sunday.

Months of the year

Month	Abbreviation	Month	Abbreviation
January	Jan	July	Jul
February	Feb	August	Aug
March	Mar	September	Sep
April	Apr	October	Oct
May	May	November	Nov
June	Jun	December	Dec

Date formats

Style	Written	Spoken
British	15th May 2024 / 15 May 2024	the fifteenth of May, twenty twenty-four
American	May 15th, 2024 / May 15, 2024	May fifteenth, twenty twenty-four

Numerical dates can be ambiguous:

• 03/04/2024 = 3rd April (British) or March 4th (American)

This is a frequent source of confusion. When in doubt, write the month as a word.

Prepositions with days, months, and dates

Preposition	Used with	Example

Common Mistakes

Not capitalizing days and months

• Wrong: I'll see you on tuesday in january.
• Right: I'll see you on Tuesday in January.
• Why: Days and months are always capitalized in English. This is a firm rule, not a style choice.

Using wrong prepositions

• Wrong: I'll see you at Monday. She was born at March.
• Right: I'll see you on Monday. She was born in March.
• Why: Days and dates use "on." Months and years use "in." Specific times use "at."

Confusing British and American date formats

• Wrong: Interpreting 01/02/2024 without knowing the format
• Right: Write the month as a word when there could be confusion: "1 February 2024" or "February 1, 2024"
• Why: 01/02 is January 2nd in American format but 1st February in British format. Always clarify.

Misspelling common months and days

• Wrong: Wendsday, Febuary, Wensday
• Right: Wednesday, February
• Why: "Wednesday" has a silent "d" (Wed-nes-day) and "February" has two "r"s (Feb-ru-ary). These are among the most commonly misspelled English words.

Usage Notes

When talking about recurring events, days can be made plural: "I work on Saturdays" (every Saturday). This is the same in British and American English.

The main British/American differences with dates:

• British: day before month (15 May)
• American: month before day (May 15)
• British: "on the weekend" is less common; "at the weekend" is used instead
• American: "on the weekend" is standard

In conversation, people often skip the year when it is obvious from context: "My birthday is on March 3rd" (not specifying the year).

Practice Tips

• Daily practice: Each morning, say today's full date out loud: "Today is Wednesday, the first of April, twenty twenty-six" (British) or "Today is Wednesday, April first, twenty twenty-six" (American).
• Birthday list: Write down the birthdays of family members and friends using full date expressions. Practice saying them with the correct preposition.
• Spelling drill: Write out Wednesday and February several times. These two words are consistently among the hardest to spell for both learners and native speakers.
