A simple way to do it is to start with an Excel Workbook.
On Sheet 1, in Cell A1, insert the word "Date"
In Cell A2, insert the formula =Today()
In Cell A3, insert the formula = A2+1
Then copy that formula down as many rows as required.
Then save this workbook and then in Word, with a new document on the screen, go to the Mailings tab of the ribbon and click on the Start Mail Merge dropdown in the Start Mail Merge section of the ribbon and select "Letters".
Then, click on Select Recipients and then on Use Existing List and then navigate to, and select the Excel Workbook that you created, selecting Sheet 1 as the source of the data.
Then, in the Word document, with the selection where you want the date to appear, using the Insert Merge Field dropdown, select the Date field and insert it into the document. Add any other text that you want to appear on each page, and save this document,
which will be your Mail Merge Main Document. Then, with that document as the active document, in the Finish section of the Mailings tab of the ribbon, click on Finish & Merge and select Edit Individual Documents.
When the process has finished running, you will have a document that contains a page for each day with the date where you inserted the merge field.
If the date is not in the format that you want it, modify the «Date» field in the Mail Merge Main document, following the procedure in the article
"Formatting Word fields with switches" on fellow MVP Graham Mayor's website at:
http://www.gmayor.com/formatting_word_fields.htm
Keep the Excel Workbook and the Mail Merge Main document as you can use them again when you want to create more pages. Just opening the Excel Workbook and recalculating it will cause the =Today() field to update to the current day and likewise all of the
dates in the cells below it will be updated.
Another way to do it is to down load fellow MVP Macropod's Word Date Calculation Tutorial from:
http://www.gmayor.com/downloads.htm#Third_party
and extract the file from the archive and then on Page 11, copy the range of dates that are highlighted in the following screen shot:
and paste them into a new document. Then starting with the second date, select it and the rest of the dates and copy and paste
them as many times as required. Then press CTRL+a to select every this and then press F9 to update the date. Finally, select everything except for the first date and format the paragraphs to have a page break before them.
