"We drink his beer in September."
Translation:Beviamo la sua birra a settembre.
In this section 4 of Time sometimes we are given 'a' followed by the month and sometimes 'in' followed by the month and it seems completely interchangeable. This time I put 'in settembre' rather than 'a settembre' and was marked as incorrect so I would love a native Italian speaking person to let me know if there is a rule for this as I am unable to fathom it out. Many thanks.
