Calcute Week Numbers Starting From 1 July Of Current Year

Hi everyone,

I want to calculate the week number of a date in a year starting from the 1 July (of the current year) - as this is the beginning of the Financial Year in Australia.

The starting day of the week is Wednesday.

I've been trying to think how I could use the Access DatePart Function in a query to calculate the week number from sales records.

I have had no trouble calculating the week number from the 1 Jan using the DatePart function. However, the function doesn't allow me to select a different date other than the first week of January.

So as a work around, I've thought of calculating the week number of 1 July in the current year, and just using the DateAdd function to add the week number to the week calculated by the DatePart Function.

Not quite working yet. Here's what I've come up with so far.


WeekNumberCount: DatePart("ww",[DateCalled],4)

I use the following to calculate the "my" starting week of the year:

StartingWeekInYear: DatePart("ww",DateAdd("ww",0,"1-July-" & Year(Date())),4)


Then I add the two together together:

MyWeekNumberCount: DatePart("ww",[DateCalled],4)+DatePart("ww",DateAdd("ww",0,"1-July-" & Year(Date())),4)


I know it needs some work to be useful for all years. Any suggestions?
