Fill non-sequential cells with dates

Howdy experts, and seasons greetings to all.....

I have a calendar/time sheet that was passed on to me. It has run out of current dates and I need to refill it.
The cells are non-sequential as you can see by the attached.

Can anyone provide a formula or script to fill them as needed to continue using for the future?

thanks

Hi SS,

It looks like your attachment is simply an image of a spreadsheet pasted over an actual spreadsheet?

What I did is remade a mockup of your sheet, using formulas. All I had to do was set a date for the first date cell, then the rest of that row was just =B2+1, =D2+1, etc. Then I just copied that block into the next week's position, and did =B2+7 and kept the +1 formulas the same. Then I just copied week 2 into week 3, week 4, week 5, without having to update anything. It is very easy to add more time to it, just copy more rows and delete any leftover actual data.

Here's what I made to demonstrate this.

thanks Matt... sorry about the image.
Here is an actual sheet.

that may be workable.
It's not exactly what I was looking for though.
When I got the spreadsheet a few years ago, I found a formula that filled/populated them all the way through the end of the current sheet. (about 2-3 years at that time)
Since them, I have copied/pasted several more years of the same formatting for future use and need to fill the date cells.
I can't find that formula now for some reason....but I seem to remember it being a fill type formula.

One change I would make to the formulas would be to verify that there is a value.

In cell D2:      =if(b2<>"",b2+1,"") and carry it through for the week (f2, h2, j2, l2 and n2)
In cell b11:    =if(b2<>"",b2+7,"") and carry it through column B cells  (b20 and b29)

nice catch...

that may already be in the (newer) version of the attached files.

If you press F5 (goto) then press Special, you can select "constants" to select just the dates. But you're still stuck with populating them.

You could use that to your advantage with a quick macro though, utilizing the formula (for easy updating later)
    Dim RG As Range
    Set RG = Cells.SpecialCells(xlCellTypeConstants, 1)
    Intersect(RG, Columns("E:O")).FormulaR1C1 = "=RC[-2]+1"
    Intersect(RG, Range("C11:C8741")).FormulaR1C1 = "=R[-9]+7"

You could always use something like this macro:

Sub AddDates()
Srow = 2
BeginDate = DateSerial(2013, 12, 30)
EndDate = DateSerial(2014, 12, 31)
NewDate = BeginDate
Do Until NewDate > EndDate
    Cells(Srow, "B").Value = NewDate
    For i = 1 To 6
        Cells(Srow, "B").Offset(0, i).Value = NewDate + i
    Next i
    NewDate = NewDate + 7
    Srow = Srow + 9
Loop
End Sub

Open in new window


You would have to set your BeginDate and EndDate or set it up to ask for those dates.

ran the macro....

it filled in about 3 columns over then down.
also dates jumped by two days, not sequentially.

can you run it against a copy of the attached file and see what mods to make?

I tested my macro on your workbook, and it took less than a second to run. Is there something missing from that? I could have it prompt you for a initial date, and then put that value into cell C2 for you if you wanted.
Or if you wanted the macro to leave you with a date value, instead of a date formula, simply put "RG.Value = RG.Value" as a last line in it.

mvidas,

That would be about correct for time.  It is very quick. There are however 2 issues with it. The first is easy enough to fix. Just change Lines 7 and 9 to be "C" instead of "B".

The second is a little more challenging.  Since it is using merged cells on the Date row I did not account for every other column. I am looking at that now but if you have any suggestions please feel free to provide them.

For the "every other column" thing, change your offset from Offset(0, i) to Offset(0, i * 2)

I hadn't tested your macro until now, so I should have refrained from posting the suggestion. The merged cell property of column C prevents the *2 from working (as the offsets really would need to be 1,3,5,7,etc). For your macro to work an easy fix would be:
Sub AddDates()
Dim Srow As Long, BeginDate As Long, EndDate As Long, NewDate As Long, i As Long
Srow = 2
BeginDate = DateSerial(2013, 12, 30)
EndDate = DateSerial(2014, 12, 31)
NewDate = BeginDate
Do Until NewDate > EndDate
    Cells(Srow, 3).Value = NewDate
    For i = 1 To 6
        Cells(Srow, 3 + i * 2).Value = NewDate + i
    Next i
    NewDate = NewDate + 7
    Srow = Srow + 9
Loop
End Sub

That does it.  I had tested it on a blank worksheet and it worked but when SeaSenor said it didn't I noticed the merged cells.  I usually avoid that feature so was having trouble with it.

Thank you all... it works well.

I had to change the Srow to a different starting point, and the end date to 12/31/2050
took about 20 seconds on a pretty fast computer.

Now I'm good past retirement (hopefully!!!)
