Does "dato" only mean the date as in the day of the month or can it also be date as in rendezvous?
Only 'date' as year-month-day. The other kind would be 'stevnemøte' or often just called 'date/deit'.
Do we refer here to a date/appointment that will take place in August or is this a way to say the month we are now? As it happens with time where we say "klokka er 9".
