"Date" (Comparison Method)

Compare two dates based on a time tolerance.

Details

The "Date" comparison method considers two date objects to be equivalent if they do not differ by a given amount of time.
This allowed time difference should be given as a time Quantity using the Tolerance option in AssessmentFunction. The default tolerance is zero seconds.
By default, the date comparison between the answer key and the answer is computed using the DateDifference function. The DistanceFunction option can be used to specify a custom temporal distance metric.
Using the default distance function DateDifference, when the granularities are not consistent, assessment is based on the smallest granularity and the starting points of dates with larger granularities.
When multiple values in the answer key are within the tolerance range of an answer, the closest value is selected.
For convenience, vectors with multiple components are also accepted as input and treated as arguments to DateObject.

Create an AssessmentFunction for a date question with a tolerance:

Use it to assess an answer:

Create an assessment with multiple possible answers at different time scales with custom scores:

Assess an answer and retrieve the score:

Assess and retrieve the score when the exact date is given:

The dates do not need to be defined at the same time granularity:

Any valid input for DateObject is supported when the "Date" method is explicitly specified:

See the answer key containing standardized dates:

Create a QuestionObject using "Date" interpretation on the inputs:

Create a QuestionObject treating years as numbers:

Using "Date" comparison with interpretation allows all common date forms:

Answers with smaller granularities than the answer key are compared to the starting point of the key and may have nonzero distances:

Create a custom distance function conforming the answer to match the granularity of the answer key:

Any value within the answer key date is marked correct:

The date comparison method will be automatically inferred only if the answer key is a DateObject:

Other date specifications will not automatically be treated as dates:

Specify the method explicitly:
