# Last updated date stamp

="Last update: "& TEXT(A1, "ddd, mmmm d, yyyy")

To add a date stamp in a workbook to indicate a "date last updated", you can use the TEXT function. In the example shown, the formula in C5 is:

="Last update: "& TEXT(B5, "ddd, mmmm d, yyyy")

The TEXT function can apply number formatting to numbers just like Excel's built-in cell formats for dates, currency, fractions, and so on. However, unlike Excel's cell formatting, the TEXT function works inside a formula and returns a result that is text.

You can use TEXT to format numbers that appear inside other text strings. In this case, we concatenate the text "Last update" with the result provided by the TEXT function, which picks up a date from column B and formats it using the supplied number format.

You can embed the date in any format you like, using the codes that represent date formats (dd, mm ,yyyy, etc.)

### With a named range

One convenient way to manage a "last updated" message in a large workbook is to use a named range to hold the date last updated, then refer to that named range in formulas elsewhere to display a last update message.

For example, you can name a cell something like "last_update", and use that cell to enter the date last updated. Once you've defined the named range, you can use the formula below anywhere you like to display the same message:

="Updated: "& TEXT(last_update, "ddd, mmmm d, yyyy")

Whenever you change the date value in the named range, all formulas will update instantly, and all date stamps will stay in sync.

### With current date

To embed the current date in a string, you can use the TODAY function like this:
