Hello Omar Cristian Martinez ,
Thank you for reaching out on the Microsoft Q&A .
The old keyboard shortcuts for date and time (Ctrl+; and Ctrl+:) aren't available in Excel 2021 anymore. No worries! You can still insert them easily. Just type "=TODAY()" for the current date or "=NOW()" for the current time. These formulas will automatically update whenever you open the spreadsheet.
I hope this helps! If you have any further questions, feel free to ask.
