    ? Days of the week, including a specific time of the day of the week

    ? I will see you on Tuesday.

    ? On Wednesday, I met my friend, Bob.

    ? In 1953, the Korean War ended.

    ? The internet was widely used in the 1990s.

    ? In the 20th century, cars became very popular.

    ? Times of day

    ? I have class in the morning.

    ? In the afternoon, I can often watch movies.

    ? I got to class in time for the test.

    ? I hope I can get to Starbucks in time. My friend will leave

    ? I will see you at 6:30.

    ? At noon, Ill eat lunch

    ? I always wake up at 5 am.

    ? My neighborhood is very quiet at night.

    o For space:

    ? At basically means near this location.

    ? Common mistakes with in/on/at

    o Not used with last or next

    ? (Wrong) On last night, I was very busy.

    ? (Right) Last night I was very busy.

    ? (Wrong) I will go to Europe in next summer.

    ? (Right) I will go to Europe next summer.

    o Not used with vacations, use over or during for specific vacations, but

    simply on for vacation alone.

    ? (Wrong) In summer vacation, I had a part time job.

    ? (Right) Over summer vacation, I had a part time job.

    ? (Wrong) I had a good time in vacation.

    ? (Right) I had a good time on vacation.


    The most common problem with these is that many students dont remember that these

    are used relative to a time other than now, for example, a time in the past or future. For

    times relative to now, you must use in for a future time and ago for a past time.

    ? Correct uses of in and ago o I will see you in 5 minutes.

    o Lets go to Europe in 2 years.

    o I saw him 5 minutes ago.

    o I met my girlfriend two years ago.

    ? I will go to the movies tonight at 8 pm. You can meet me 2 hours


    ? I hope to graduate in 2010 and start my own company after 5 years.

    o Of course, later can also be used alone to mean later than now.”

    ? See you later!

    ? My uncle got married last year. He had met his wife 5 years


    ? I hope to start my own company in the year 2015. Ill graduate

    from college 5 years before that.

    ? Common Mistakes with after/later/before

    o Notice the placement

    ? after goes before what its describing

    ? later goes after what its describing

    ? before goes before a clause but after a time.

    o Remember, they arent used with a time relative to now


    ? By

    o By is used for a one time action. The action must happen before the

    time you state.

    ? I must wake up by 6 am.

    ? 6 am is the last possible time that waking up is okay. 5
