In compliance with the national standard in the United States, GoDaddy Bookkeeping defines Sunday as the first day of the week and Saturday as the seventh and last day.
Therefore, your weekly reports in GoDaddy Bookkeeping include and display transaction data beginning on Sundays and ending on Saturdays.
This is particularly important information for GoDaddy Bookkeeping's international customers, as international standards oftentimes differ from this convention. Unfortunately, GoDaddy Bookkeeping does not currently offer a feature where the user can define their own local weekly standard.
Personally, I'd like to be able to define my own local weekend standard. Friday through Monday sounds good!
