How to Make a Cell on Microsoft Excel With a Changing Date. Microsoft Excel offers a Function Library with formulas that insert the current date when you open the worksheet or enter calculations.

If you're using Microsoft Excel, you insert the current date in a spreadsheet with the Ctrl-; keyboard shortcut. Select a cell, press the "Ctrl" key and then enter ";" (semi-colon).

Use either keyboard shortcuts or the NOW and TODAY functions to display the current date and time in Excel and Google Sheets spreadsheets together.

Microsoft Word has a date field, but it's not easy to use in an expression. If you need to update dates in a document, use Excel to calculate the dates and then run a mail merge.
