How should I say the date written 'on 27 July' correctly? I was taught that such date can be read only as 'on the 27-th of July'. So my question is whether it's omitted only in written form and we have to say 'the implicit information' (or how to put it...) or it can really be said as it's written adding only -th-: 'on 27-th July'.
EDIT: I often come across this form of date in Wikipedia: 'on + number + year'. And I want to know if this written form is correct for British English. Then, if it is correct, then does it mean that one should add the words the and of when he's reading this date from that text?
