RE: Now function
Hi Judith
Thank you for your question and welcome to the forum.
The =NOW() function itself provides the current date and time, when the cell it is entered into is formatted correctly.
You may or may not find it useful depending on what you are using Excel to do, but for example it could be used as part of a longer formula to figure out the number of hours and minutes that had passed/lapsed between two different times entered into a spreadsheet.
Kind regards
Amanda
