    Nội dung bài viết
    A. Compare When ...? (+ past simple) and How long ...? (+ present perfect):
    A: When did it start raining?
    B: It started raining an hour ago/at 1 o'clock.
    A: How long has it been raining?
    B: It's been raining for an hour/since 1 o'clock.
    A: When did Joe and Carol first meet?
    B: They first met a long time ago/when they were at school.
    A: How long have Joe and Carol known each other?
    B: They've known each other for a long time./since they were at school.
    B. We use both for and since to say how long something has been happening.
    We use for when we say a period of time (two hours, six weeks etc.):
    * I've been waiting for two hours.
    for two hours
    two hours ago -> now
    two hours/a week/20 minutes/50 years/five days/a long time/six months/ages
    * Sally's been working here for six months. (not 'since six months')
    * I haven't seen Tom for three days. (not 'since three days')

    We use since when we say the start of a period (8 o'clock, Monday, 1985 etc.):
    * I've been waiting since 8 o'clock.
    since 8 o'clock
    8 o'clock -> now
    since
    8 o'clock/1977/Monday/Christmas/12 May/lunchtime/April/they were at school
    * Sally's been working here since April. (= from April until now)
    Source: hoctienganh1.com
    * I haven't seen Tom since Monday. (= from Monday until now)
    It is possible to leave out for (but not usually in negative sentences):
    * They've been married (for) ten years. (with or without for)
    * They haven't had a holiday for ten years. (you must use for)
    We do not use for + all ... (all day/all my life etc.):
    * I've lived here all my life. (not 'for all my life')
    C. We say 'It's (a long time/two years etc.) since something happened':
    * It's two years since I last saw Joe. (= I haven't seen Joe for two years/the last time I saw Joe was two years ago)
    * It's ages since we went to the cinema. (= We haven't been to the cinema for ages)
    The question is How long is it since ...?
    * How long is it since you last saw Joe? (= When did you last see Joe?)
    * How long is it since Mrs Hill died? (= When did Mrs Hill die?)
