The particle に is used with specific time expressions to mark the exact time when something happens. Think of に as pointing to a time on a clock or calendar. It answers “when?” in a precise way. Key points: • Use に with specific times: 7時に, 3月に, 日曜日に • Use に with days and dates: 月曜日に, 8月10日に • Do NOT use に with relative time words like 今日, 明日, 毎日 • に comes after the time word For example, “7時に起きます” means “I wake up at 7.” “日曜日に行きます” means “I will go on Sunday.” If the time is not specific (like “every day” or “this week”), you usually skip に: “毎日勉強します.” Using に helps make your timing clear and polite. It is one of the first particles learners use, and it pairs well with basic verbs like 行きます, 来ます, and 起きます. Practice by adding に to exact times: 5時, 火曜日, 6月. Then make simple sentences about your schedule.
