DateTime.IsInNextHour

DateTime.IsInNextHour is a Power Query M function that indicates whether the provided date(time) value occurs during the next hour. The function returns true if the value occurs in the next hour, otherwise false.

Compatible with: Power BI Service Power BI Desktop Excel Microsoft 365

Syntax

DateTime.IsInNextHour( dateTime as any ) as nullable logical

Description

DateTime.IsInNextHour indicates whether the given dateTime argument (which can be of type datetime or datetimezone) occurs during the next hour, as determined by the current date and time on the system. This function will return false for a value within the current hour.

Examples

Let’s explore two examples to understand how the DateTime.IsInNextHour function works.

Checking DateTime Values for the Next Hour

Suppose you have a table with DateTime values and you want to add a column that shows true for DateTime values that fall within the next hour. You can do this by using the DateTime.IsInNextHour function on your [DateTime] column.

DateTime.IsInNextHour( [DateTime] ) // Output depends on [DateTime] column

This expression returns true for any DateTime values in the [DateTime] column that fall within the next hour.

If the current time is 10:26:14 PM on July 7, 2024, this function will return true for all rows with DateTime values between 11:00:00 PM and 11:59:59 PM.

Here’s a screenshot to illustrate how the DateTime.IsInNextHour function works with a DateTime table:

In this example, the DateTime values increment by 15 minutes for each row. The column IsInNextHour shows true for the four DateTime values that fall within the next hour.

Using the Current Date and Time

If you want to check with DateTime.IsInNextHour if the current date and time falls within the next hour, you can do that using the DateTime.FixedLocalNow function and adding one hour using the #duration function:

// Output: true for the next hour
DateTime.IsInNextHour(
  DateTime.FixedLocalNow() + #duration(0, 1, 0, 0)
)
