Time idioms are common English expressions that help speakers describe urgency, schedules, experiences, and the way time affects our lives. Native speakers use these phrases every day because they make conversations sound more natural, expressive, and engaging.
Instead of understanding these expressions word by word, English learners should learn them as complete phrases with their meanings and real-life examples.
