The relatively holiday free August printable calendar is here. Whether you use the letter size or the ISO A4 format pages is entirely your own business. I wash my hands of the whole affair. But if you want to arrange your schedule around the UK Bank Holidays, the A4 version will serve you best.
I wonder, do people from Berwick-upon-Tweed (at war with Russia since 1853 because of a clerical oversight) get both Scottish and English Bank Holidays off? That would be nice for them.
