Just out of curiosity, I was going to ask why your week started on Monday:

>    type Day_Name is
>      (Monday, Tuesday, Wednesday, Thursday, Friday, Saturday,
> Sunday);

>    function Week_In_Year (Date : Ada.Calendar.Time) return
> Week_In_Year_Number;
>    --  Returns the week number in the year with Monday as first
> day of week

and then I noticed the comments in GNAT.Calendar.Time_IO:

>  It follows the GNU Date
> specification. Here are the recognized directives :
>    --          Date fields:

>    --          %A   locale's    full   weekday   name,
> variable   length
>    --                  (Sunday..Saturday)
>    --          %U   week number  of year with  Sunday as first
> day  of week
>    --                  (00..53)
>    --          %w   day of week (0..6) with 0 corresponding to
> Sunday
>    --          %W   week number  of year with  Monday as first
> day  of week

which implies that, although it's acceptable in GNU to start counting weeks
on either Sunday or Monday, the first (zero'th) day of the week is always
Sunday? Is this right?
