End of maintence period - date format used

Sorry if this sounds a daft question, as just related to customer renewal accounts, but what date format do you use for your end of maintenance period in accounts ?

eg “Your maintenance period expires on: 2015-08-06” - does this mean it end’s on the 6th August 2015 or the 8th June 2015 ?

Thanks.

Just curious when I need to renew it by

It’s in English format. So 6th August 2015

Cheers - reason for asking is that American date formats tend to be different from British formats.
