When using Access to insert data into a SQL Server table, it is recommended to use the YYYYMMDD hh:nn:ss format, this minimises problems with international date/time formatting.

Week Numbers

The option for weeknumbers (ww) is buggy for certain weeks/years. To produce a correct ISO 8601 weeknumber use a function, if this is saved in a module it can be used in VBA or in an SQL query:

Function ISOWeekNum(dtmDate) 
' Returns a WeekNumber from a date 
   Dim NearThurs 
   NearThurs = ((dtmDate+5) \ 7) * 7 - 2 
   ISOWeekNum = ((NearThurs - DateSerial(Year(NearThurs), 1, 1)) \ 7) + 1 
End function
 
' Example 
 wscript.echo "ISOWeekNumber: " & ISOWeekNum(cdate("2017-12-25"))
