The NOW function

Returns the current date and time. It updates every time the sheet recalculates, so it is a live clock, not a timestamp.

Syntax

NOW()

Examples

B1=ISNUMBER(NOW())
AB
1TRUE
B1=INT(NOW())-TODAY()
AB
10
B1=IF(NOW()>DATE(2024,1,1),"After Jan 1, 2024","Before")
AB
1After Jan 1, 2024

Questions

How do I enter a timestamp that does not change?

Type it with a shortcut instead of a formula. On Windows, Ctrl+; enters today's date and Ctrl+Shift+; the current time. On a Mac, use Ctrl+; and Cmd+;.

What is the difference between NOW and TODAY?

TODAY returns the date only, as a whole number. NOW adds the time of day as a fraction, so at 6 PM it is 0.75 more than TODAY.
