Explain the DATE Function ' NOW' in Tableau with Example?

In Tableau, the NOW function is used to retrieve the current date and time based on the system's clock. It returns a datetime value representing the current moment when the function is executed.

The NOW function does not require any arguments and can be used directly in calculations or formulas.

Here's an example to illustrate the usage of the NOW function in Tableau:

NOW()

In this example, the NOW function is used without any arguments. It will return the current datetime value at the time when the function is executed.

The resulting output will be a datetime value representing the current date and time.

The NOW function in Tableau is particularly useful when you want to include the current date and time in your analysis, calculations, or visualizations. You can use it to calculate durations, compare dates and times, track real-time data, or create time-based filters and calculations.

It's important to note that the NOW function retrieves the current date and time from the system on which Tableau is running. Therefore, the result may vary depending on the system's clock and time zone settings.
