update dates in excel spreadsheet each yearSolved/Closed

Question

Hello,
i have 4 spreadsheets linked together which i use to keep track of my accounts.

all 4 spreadsheets are in one folder.

On each spreadsheet i have the date mon to sun with a weekly total underneath for each month running down column A.

My dilema is that each year i have to copy all the floder, wipe all the data leaving the formulas in, and delete all the dates and change to next year as obviously each year the 1st will not land on the same day therefore i have to go through the long process of deleting all and re typing in the days, dates for each week, add a row for total at end of week and carry on like that so each page is a different month and the weekly totals run all the way through the year wk1, wk2, wk3, wk4, wk5, wk6 etc.

Does anyone know of an easier way of excel knowing what day the new year begins and inserts it into a new spreadsheet????? 

Please please help!!!!!

If i can help it i wuld prefer to carry on using excel for my accounts

HELP ME!!!!!

see whether this macro will help you. The macro will bring up an input box. there type the year for e.g. 2010 or 2011. (I assume you wont extend to the end of the century).you can format date column A as you like. 
test the macro and decide.

your second question is not clear to me. 

Sub test()
Dim y As Integer, d As Integer
y = InputBox("type the year, e.g. 2010")
If y Mod 4 = 0 Then
d = 366
Else
d = 365
End If
Range("a1") = "1/1/" & y
Range(Range("A1"), Cells(d, "A")).DataSeries Rowcol:=xlColumns, _
Type:=xlChronological, Date:= _
        xlDay, Step:=1, Trend:=False
Range("B1").Formula = "=weekday(A1)"
Range("B1").AutoFill Range(Range("B1"), Cells(d, "B"))
End Sub

A1 is having an entry 1/1/09. now in B1 enter this formula 
=WEEKDAY(A1)
you will get  5
the weekday starts from Sunday in this formula 
1 Sundnay, 2 Monday, 3 Tuesday, 4 Wednesday , 5 Thursday, 6 Friday and 7 Saturday.

if  you want to check enter in some cell  e.g. A5 today's date (11/8/09)
and in the next cell to the right in B5 type 
=WEEKDAY(A5)
you will get 1 which is Sunday

Will this information be useful to  you.

i too would like to know how to go from year to year without having to clear all my data from say 2009, then start with 2010 with what is essentially a new spreadsheet...

i used to know how, but not being the PC geek anymore...into other things...but there has to be an easier way? anyone?
