A quarter till refers to a time that is 15 minutes before the next hour. For example, if the clock shows 3:45, it is said to be a quarter till 4. To break it down, the term ‘quarter’ represents the 15-minute interval, and ’till’ indicates that we are counting down to the next hour.
Essentially, when someone asks for the time and you want to express it as a quarter till, you are telling them the last quarter of that hour has arrived. This expression is commonly used in casual conversation, making it a friendly and easy way to communicate time.
