    Does the quotation in red mean that 21.00 can read either "twenty-one hours" or "twenty-one hundred hours"?

    Twenty-one hundred or twenty-one hundred hours

    Google "military time".

    It certainly appears to be what they're suggesting but I disagree with them. If it's exactly 9pm, then it's only worded "twenty-one hundred hours", and only when using "military time". From 9.01pm onwards, the hundred would be omitted. 2105 = twenty-one oh five.
    Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.

    I agree, BrE usage would be "twenty-one hundred" or more likely to read it aloud as "nine PM".

    "Military time" is an American expression which would cause most British people to be puzzled. Twenty-four hour times are universal in transportation schedules in Europe and most of us will happily switch between systems in mid conversation.

    I think quite a lot of BrE speakers would understand it but it's certainly more common to the use the term "the 24-hour clock".

    Bob: How would you express 9pm using the twenty-four hour clock?
    Jane: Twenty-one hundred [hours].

    I don't think anyone is saying "fourteen minutes to eleven" for 10:46. Five till, ten till, quarter till all are natural. Not numbers not divisible by 5.

    Re: 21.00 twenty-one (hundred) hours

    I agree with Dave. I obviously can't speak for everyone, but I tend to round to the nearest unit of 5 for that very reason, unless there's a need to be precise. If so, then I'll just use the straight number format, and not mess with the to/past format.

    For example, at 10:46, I'll just say "(about) a quarter to 11". If I need to be exact, then "10:46" For something like 10:08, then it's either "10 past ten" or "10:08".

    I'm writing this post at a quarter past 5 local time. (But it's really 5:17 by the clock on my wall.)

    It does, but I would say it should be twenty-one hundred (hours).

    I haven't read every word of this thread closely, but I don't think anybody says 'twenty-one hours'.
