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 Microsoft Excel's TODAY() function in simple expressions to highlight the current date and past and future dates.

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

To ensure that a date column is used correctly, you can effectively insert a calendar in Excel, using an Excel date picker.
