How Can I Efficiently Check if a Date Falls Within a Range of Dates?

Determining Date Inclusion within a Range

In a scenario where you possess a collection of date intervals defined by start and end dates, you may need to verify whether a specific date falls within any of these ranges. Instead of relying on the seemingly cumbersome Date.before() and Date.after() methods, a more streamlined approach is available.

The following code snippet exemplifies a simplified version of your desired pseudocode:

boolean isWithinRange(Date testDate) {
   return !(testDate.before(startDate) || testDate.after(endDate));
}

This implementation effectively checks if the testDate is neither before the start date nor after the end date, thereby determining its inclusion within the specified range. It's worth noting that this condition also accounts for scenarios where the testDate coincides with the start or end dates, ensuring accurate range verification.
