Knowing how to tell the time is one of the most practical skills you can develop when learning English. Every conversation, meeting, or daily plan involves time, so mastering the right expressions will boost your confidence and make your communication much more natural.

How does the clock work in English?

Before learning the expressions, it is essential to understand how the clock is divided. The minute hand (the big hand) determines which expression you use. The clock is split into two halves, and each half follows a different rule [0:22].

• When the minute hand points to 12, you say o'clock.
• From minute 1 to minute 30, you use the preposition past.
• From minute 31 to minute 59, you use the preposition to and refer to the next hour.

This distinction is the foundation of telling time correctly. In English, the structure is always: minutes + expression + hour. For example, it's quarter past four [0:46].

What do quarter past and half past mean?

Three key expressions appear constantly when talking about time:

• Quarter past: 15 minutes after the hour. You can also say 15 past, but quarter past is more common [0:33].
• Half past: 30 minutes after the hour. Saying 30 past is correct, yet half past is the preferred form [0:57].
• Quarter to: 15 minutes before the next hour. Here you already switch to the preposition to and mention the upcoming hour [1:04].

For instance, when it is 4:45, you say it's quarter to five, because there are 15 minutes left to reach five [1:15].

How do you practice with real examples?

Using four o'clock as a base, the full sequence sounds like this [1:38]:

• It's four o'clock.
• It's five past four.
• It's ten past four.
• It's quarter past four.
• It's twenty past four.
• It's twenty-five past four.
• It's half past four.

Once you cross the half-hour mark, the pattern changes [2:30]:

• It's twenty-five to five.
• It's twenty to five.
• It's quarter to five.
• It's ten to five.
• It's five to five.

You can also use mixed numbers like it's twenty-three past four or it's twelve past five. The sharp numbers above are simply a reference to help you memorize the structure [2:17].

Is saying "it's 4:45" acceptable in English?

In very informal English, saying the digits directly — it's 4:45 or it's 4:50 — is technically accepted [2:50]. However, in formal settings, presentations, or exams, you should follow the to and past rule. Understanding both registers lets you adapt to any context.

How can you match clocks to written time?

A useful exercise is connecting clock images with their written descriptions [3:20]. Here are three quick examples:

• A clock showing 3:20 matches it's twenty past three [3:34].
• A clock showing 1:00 matches it is one o'clock [3:40].
• A clock showing 11:55 matches it is five to twelve [3:45].

Remember, you can use the full form it is or the contraction it's — both are correct [3:50].
