For example instead of saying two, thirty. (2:30) you say "half past". Which is simply ridiculous!Well its interchangeable, although half past isn't the confusing. If you said "half past two" to someone who'd never heard it before they could easily work out that you mean half an hour past two o'clock. It is easier just to say the numbers though, which is how I normally say the time. Like twenty to three makes sense and most british people would say it that way but two forty is just much easier for everyone.
At least we're not like the Germans, who for 2:30 would say "halb drei" or half three, as in halfway to three o'clock. Now that's weird
