When should you use a に when talking about the time?


Over time, I've realised that certain words you use when referring to time,
such as ’今日’, ’明日’ and ’毎朝’ have no need for you to attach the に particle.
However, when saying '六時’, you must attach a に.

For example, ’今日、学校に行きません。’ and ’毎日午前六時におきます。’




You should use に when the 'time' word means a particular time, for example, 六時
which is 'six o'clock.' You don't need to, however, if the word implys a
period, such as 今日, and the action word can mean a kind of status.
