Modifying Default Year for Dates

When entering dates into a worksheet, Excel provides quite a bit of latitude for how you enter them. One area where latitude is granted is when it comes to including a year. If you include a year (such as 3/2/08), that is great. If you don't include a year (such as 3/2), then Excel helpfully adds the current year to what you are entering.

Most of the time this isn't a problem. It can be a problem, however, for those entering dates that "wrap around" to last year. For instance, many people enter dates for the previous month or two in their worksheets. In most months this isn't a problem, because the past month or two is in the same year as the current month. It can be a problem during January and February, however, when you may be entering dates from November and December of the previous year.

One solution is to always enter the year when entering a date. It is unarguably faster to leave the year off during data entry and allow Excel to add it to your entry. Thus, it would be nice to come up with a way to enter dates during the first two months of the year and have the previous year's year appended to them.

One way to handle this is to change the system date on your computer. Within Windows, decrement the system date by one year. Then, all dates that you enter will change to last year. This has ramifications in other programs, however, unless you remember to change the system date back. It also can mess up your data entry if, during the latter part of January and early February, you start entering dates from this year, and Excel automatically appends last year's year to them.

Doing anything more complex necessarily involves the use of a macro. Consider the following example, which should be added to the code window for a worksheet:

Private Sub Worksheet_Change(ByVal Target As Range)
    If Target.Cells.Count > 1 Then Exit Sub
    If Target = "" Then Exit Sub
    If Target.Column <> 1 Then Exit Sub

    If DateValue(Target) > Date Then
        Application.EnableEvents = False
            Target = DateAdd("yyyy", -1, Target)
        Application.EnableEvents = True
    End If
End Sub

This macro automatically runs whenever there is a change in the worksheet. If the change being made is to a single cell in column A, and what is being entered is a date that is greater than today's date, then a year is subtracted from what is being entered.

This works great, provided you are routinely entering dates that are within either the last year or the months so far in the current year. If you specifically add a far-future date (such as entering 6/11/17 on 3/2/16), then the year is still incremented by one. The macro could, of course, be modified to check to see if the date being entered is in the last two months of a year, and that the date is actually being entered during the first two months of a year, before doing the decrement of the year.

Donna,

Did you find an answer for your question? I am having the same issue.

"If you include a year (such as 3/2/08), that is great. If you don't include a year (such as 3/2), then Excel helpfully adds the current year to what you are entering." This helpful feature is not working in my application. I am using Excel 2016 and Windows 7 Pro. When I input a date e.g. "jan 26" with the following date format dd/mm/yyyy, Excel returns 01/01/2026. I am stumped as to why it's doing this. It doesn't matter if I use English or Canada. The date is correct in Windows. Any suggestions as I would prefer to not have to enter the year every time. Thx.
