    Hi there,
    Which way of telling the round hour is corect "It's five o' clock a.m./p.m." Or only "It's five o' clock" or optionally " It's five a.m./p. m"?

    And are the numbers from 1 to 24 used in telling the time digitally or just numbers from 1 to 12 and abbreviations a. m. / p. m.
    For example:
    14.30. or
    2. 30 p. m.?

    Greetings,

    It's five o'clock a.m./p.m. :cross:
    It's five o'clock :tick:
    It's five a.m./p.m. :tick:

    14.30 is correct, but I think I would use it in writing only, not in speech.

    If I say o'clock, I don't say a.m. or p.m.

    I would say 5 o'clock in the morning, or 5 o'clock in the afternoon.

    I do say 5 a.m. and 5 p.m.

    The other possibilities are "military time" or "army time"
    05:00 which is read as zero five hundred hours or oh five hundred hours
    and
    17:00 which is read as seventeen hundred hours.

    You can leave out the "hundred".

    I would not say 17 o'clock.

    24 hour clock times are never used in spoken or informal language, but they are used in timetables, and on some digital clocks.

    I appreciate all the replies. :)

    Brioche,
    Your information is interesting but to consider it further
    can we use " the military time" to say for example this time:
    17.25? And if yes how would it be read?

    I would say: "It's seventeen twenty-five." But I would immediately convert it to "five twenty-five". I'm not in the military. :)

    (I'm also not sure about the placement of hyphens in such numbers.)

    If there is any question about the time of day, I would add PM or AM. There are obvious advantages to a "24 hour" system, and some of the people I know who live in other countries always use it. :)

    Good morning :)
    I'm also concerned about this topic and would like to know, if it's correct to write zeros with "o' clock", for example,
    5.00 o'clock in the morning

    I think they can be omitted, but is it a mistake to use them here?

    No zeros.

    It is 5 o'clock.
    It is five o'clock.

    Is "o'clock" uncessary in the following sentence?
    I would like to invite you to have dinner at my house at 7 o'clock p.m. on Saturday, May 15.

    Yes, it is unnecessary. But it's not wrong to use "o'clock." Your choice!

    (I would also think p.m. is unnecessary, since dinner would naturally be at 7 in the evening. But that's again a matter of choice and style.)

    I think o'clock does not go with am or pm. One or the other: either 7 o'clock or 7 pm​. As lucas says, pm is not necessary, but if you wanted an indication of the time of day, I would say 7 o'clock in the evening.
