Excel may return a serial number instead of a date; because it is stored thus in the backend. Learn how to convert Serial Number to Date.

In this tutorial, you’ll learn what a timestamp is and then how to use Excel functions MIN () and MAX () to return the first and last call for the day from timestamps.

While Microsoft Excel automatically reformats time values as hours and minutes, you can manually change the cell's time format to display the seconds as well.

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

The date will display in the format you choose, no matter how you enter it. If you type "1/1/19" into a cell with the long date format, Excel will change it to the expanded date.
