Fuzzydate

Fuzzy dates are calendar dates which may be incomplete. For instance, one might know that a person is born in 1980, or in April, 1980, but not on which day exactly. In the database, a fuzzy date is represented by two normal dates, together indicating the range of possible values.

This is a demonstration of Yii2 Fuzzydate, a suit of classes to work with fuzzy dates in the Yii 2.0 PHP framework.
