1. What is the NOW Function & How Does It Work?
The NOW function returns the current date and time serial number of your operating system. Like TODAY(), it requires zero parameters inside its parentheses: =NOW().
While TODAY() only returns a date (e.g. 2026-08-12), NOW() includes fractional time values (e.g. 2026-08-12 14:30:15).
