Hi,

With a given base date say of 1/1/2014, I would like to create a record set of 52 records incrementing the date by 1 week in each record so it is the same day-of-week in each date (taking Leap year into account).  Each record also needs to be consecutively numbered beginning with 1 on the base date and 52 on the last.

Macro's are nice but I think this needs to be VBA.  

Help is appreciated.

Hi Charlie

Some code like this should do the trick:
Dim db As DAO.Database
Dim iWeek As Integer
Dim dtWeek As Date
Set db = CurrentDb
dtWeek = DateSerial(2014, 1, 1)
For iWeek = 1 To 52
    db.Execute "INSERT INTO [YourTable] ([NumField], [DateField]) " _
        & "VALUES (" & iWeek & ", " & Format(dtWeek, "\#yyyy-mm-dd\#") & ");"
    dtWeek = dtWeek + 7
Next iWeek

You can also use a tally/number table for this, as I show in this article:
http://www.experts-exchange.com/A_5410.html

I showed the example of sequential dates in the article.  You can multiply the number table values by 7 to get the week intervals you seek.

For such a loop you would, of course, use DAO:
Public Sub PopulateWeeks(ByVal datStart As Date)

    Const clngWeeks As Long = 52
    
    Dim dbs         As DAO.Database
    Dim rst         As DAO.Recordset
    
    Dim lngWeek     As Long
    
    Set dbs = CurrentDb
    Set rst = dbs.OpenRecordset("select * from tblWeek")
    
    For lngWeek = 1 To clngWeeks
        rst.AddNew
            rst!Id.Value = lngWeek
            rst!WeekDate = DateAdd("ww", lngWeek - 1, datStart)
        rst.Update
    Next
    rst.Close
    
    Set rst = Nothing
    Set dbs = Nothing
    
End Sub

Open in new window

You will have to adjust table and field names to those of yours.

Thank you both for responding, however, its' going to be a week or 2 before I can test the solutions.  I will get back to this.

Thank you both for the solution.  One seemed easier but didn't account for leap year.  I think I can come up with a solution that uses both.

Thank you!

You are welcome!

You could use DateAdd with the db.Execute method to account for leap years, but why would you? DAO is much faster here and does it all.

You're saying this will execute faster?

Yes. 52 calls of db.execute is not very fast.

But why don't you try? It shouldn't take you more that a few minutes ...
