Examples

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

Checking DateTime Values for the Current 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 current hour. You can do this by using the DateTime.IsInCurrentHour function on your [DateTime] column.

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

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

If the current time is 9:55:37 PM on July 7, 2024, this function will return true for all rows with DateTime values between 9:00:00 PM and 9:59:59 PM.

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

In this example, the DateTime values increment by fifteen minutes for each row. The column IsInCurrentHour shows true for the four DateTime values that fall within the current hour.

Using the Current Date and Time

If you want to check with DateTime.IsInCurrentHour if the current date and time falls within the current hour, you can do that using the DateTime.FixedLocalNow function:

// Output: true
DateTime.IsInCurrentHour(
  DateTime.FixedLocalNow()
)
